Which pages to convert All pages Only the pages I list

Pages

A single page is 7, a run of pages is 8-10, and you separate them with commas. Pages come out in the order you type them; a page listed twice is converted once; a range that runs past the last page is refused.

Output format

Resolution

JPG quality 0.92

0.6 is the smallest file and 1.0 the least compression. This slider is ignored for PNG output, because PNG is always lossless.

A4 pages become 595 × 842 px at 72 DPI, 1240 × 1754 px at 150 DPI and 2480 × 3508 px at 300 DPI. Text is re-drawn as pixels, so the result cannot be selected or searched — 300 DPI files are roughly four times the pixels of 150 DPI on each side, and PNG is usually several times larger than JPG.

What is a PDF to JPG converter?

A PDF to JPG converter turns each page of a PDF into its own image file. A PDF page is not a picture: it is a set of instructions — text with fonts, vector shapes, embedded images — that a reader draws on the screen. A JPG is a fixed grid of pixels. Converting means drawing a page at a chosen resolution and saving that drawing as a picture, and that is exactly what this page does.

The conversion is done by pdf.js, the open-source PDF renderer maintained by Mozilla and used in Firefox, together with the browser's own canvas encoder. The page is drawn onto a canvas at the size you ask for and then encoded to a JPG or a PNG in your browser. Nothing is uploaded, there is no queue and no account: the file is read from your disk, the images are written back to your disk, and the bytes never leave your device.

Two things change when a page becomes an image, and both are worth knowing before you convert. First, text stops being text — it can no longer be selected, copied, searched or read by a screen reader, because it is now a pattern of pixels. Second, JPG is a lossy format: it throws away detail that the eye rarely notices, which is why it produces small files. If you need the page to stay sharp and text-heavy, choose PNG instead; if you need small files for photos and scans, choose JPG.

How to use this PDF to JPG converter

Press Choose a PDF file and pick the document. The tool shows the file name, the page count and the file size; nothing is uploaded.
Leave All pages selected, or choose Only the pages I list and type a range expression such as 1-3, 7.
Pick the output format: JPG for photos and scans, PNG when text has to stay crisp and lossless.
Pick the resolution. 72 DPI matches what a PDF reader shows on screen, 150 DPI is a good general purpose size, and 300 DPI is print quality.
For JPG, set the quality slider. Leave it near 0.9 unless you need the smallest possible files.
Press Convert to images. Each page is rendered in turn; the list fills with the page number, the pixel dimensions and the file size of that image.
Press Download on a single page, or Download all to save every image in sequence.

Worked example

The test file is quarterly-report.pdf — a real 3-page A4 document (595.28 × 841.89 points, Helvetica text, one page with two vector shapes) that is 2,369 bytes (2.31 KB). It was converted on this page with the default settings: all pages, JPG, 150 DPI, quality 0.92. The numbers below are what the tool reported, and the same run is repeatable by loading the same file.

quarterly-report-page-1.jpg — page 1, 1240 × 1754 px, 67,443 bytes (65.86 KB)
quarterly-report-page-2.jpg — page 2, 1240 × 1754 px, 69,667 bytes (68.03 KB)
quarterly-report-page-3.jpg — page 3, 1240 × 1754 px, 58,845 bytes (57.47 KB)

Three pages in, three images out, one file per page, 191.36 KB in total. Every image is 1240 × 1754 px because every page is the same A4 size and the same 150 DPI was used: 595.28 ÷ 72 × 150 = 1240 px wide and 841.89 ÷ 72 × 150 = 1754 px high, rounded to whole pixels. A landscape A4 page would come out 1754 × 1240 px instead — the tool reports the real numbers, so a swapped pair is the page orientation, not an error.

Page 3 is the smallest of the three because it holds nothing but text, and flat text compresses well in JPEG; page 2 is the largest because of the filled shapes. A photographed or scanned page would be much larger at the same settings, because a scan is full of detail the encoder cannot throw away for free.

Two more runs on the same file, both with all three pages, show how the settings move the numbers. At 150 DPI with PNG the dimensions are identical (1240 × 1754 px each) but the total is 282.70 KB — 1.5 times the JPG total for this text-heavy document; a photo page would show a much bigger gap, because PNG does not discard detail. At 72 DPI with JPG the pages become 595 × 842 px and the whole set is 63.90 KB, about a third of the 150 DPI result. Raising the JPG quality from 0.92 to 1.0 at 150 DPI grew the same three images from 191.36 KB to 317.10 KB and changed nothing visible; lowering it to 0.6 cut them to 120.25 KB, with the text edges starting to look soft. That is the whole trade-off in one line: pixels cost file size, and quality above about 0.9 buys very little.

Who is this PDF to JPG converter for?

Anyone filling in an upload form that accepts images but not PDFs — a passport or ID portal, an expense app, a job board or a school form. Convert the page, upload the picture.
Teachers and students who need a slide, a diagram or a page of notes as an image they can drop into a presentation, a chat thread or a worksheet without losing the layout.
Office and admin staff who have to paste a signed page into an email, a ticket or a chat where a PDF attachment would be ignored.
Designers and developers who want a quick page thumbnail or a mock-up image, and would rather not open a desktop design tool for one page.
People with confidential documents — contracts, payslips, medical letters, bank statements. Because the rendering happens in the browser, those pages can be converted on a work laptop without handing the file to a third-party server.
Anyone who wants a preview image of the first page of a document for a catalogue, a listing or a file browser.

Choosing the resolution and format

The resolution decides how many pixels each page is drawn with, and it is the single biggest factor in both sharpness and file size. Double the DPI and each page has four times the pixels, which means four times the drawing work and usually a substantially larger file. The table below gives the exact pixel dimensions this tool produces for the two commonest page sizes.

Resolution	A4 page (210 × 297 mm)	Letter page (8.5 × 11 in)	Megapixels	Good for
72 DPI	595 × 842 px	612 × 792 px	0.5	Screen preview, thumbnails, what a PDF reader already shows
150 DPI	1240 × 1754 px	1275 × 1650 px	2.2	Slides, chat, email, forms, reading on a tablet
300 DPI	2480 × 3508 px	2550 × 3300 px	8.7	Print, OCR, archiving, anything that will be zoomed into

JPG or PNG? JPG is the right default for scans and photographs: it is smaller, it is accepted everywhere, and at quality 0.9 and above the difference from the original is hard to see. It is also lossy — every save throws away a little detail, which shows up first around small text and thin lines, and it cannot store transparent pixels. PNG is lossless and keeps text and line art crisp, at the cost of a larger file: in the worked example above, the same three text pages were 282.70 KB as PNG against 191.36 KB as JPG, about one and a half times the size. On photographic pages the gap is usually much wider, because PNG keeps detail that JPEG is happy to drop. Choose PNG when the image will be read closely, printed, or fed to OCR; choose JPG when size matters more than the last few percent of fidelity.

What this tool cannot do. It renders whole pages. It does not pull the original images out of the PDF at their native resolution — an embedded 4000 px photo will come back re-sampled to whatever page DPI you chose. It does not remove a password, and it does not make a scan sharper: rendering is a one-way copy, so a 150 DPI scan converted at 300 DPI is a bigger file with the same detail. It also does not write a text layer, so an image produced here cannot be searched with Ctrl+F.

Common use cases

Turning the first page of a report into a preview thumbnail for a listing or a file browser.
Converting an ID, a certificate or a signed page into a JPG because a portal only accepts images.
Dropping pages of a PDF into slides, a chat thread, a Notion page or a ticket as pictures.
Making a page image you can annotate in a photo app or on a phone, where editing a PDF is awkward.
Feeding page images into an OCR tool or an image-to-text service that does not accept PDFs.
Making a lightweight preview set of a large document without sharing the document itself.

Pro tips

Start at 150 DPI. It is the best balance for most jobs. Move down to 72 DPI when the image is only going to be looked at on screen, and up to 300 DPI only when it will be printed or read by OCR.
Convert the pages you need, not the whole file. A 300-page catalogue at 300 DPI is a lot of rendering and a lot of disk. Type 1, or 1-3, and save everything.
Use PNG for text, JPG for pictures. Mixed documents are usually best served by converting the text pages as PNG and the photographic pages as JPG, in two runs.
Quality 0.9 is usually enough. On the test file, moving from 0.92 to 1.0 grew the three images from 191.36 KB to 317.10 KB with no visible gain, while 0.6 cut them to 120.25 KB with softening around the text. Leave the slider alone unless you have a size limit to hit.
Allow multiple downloads. Your browser may ask permission the first time Download all saves several files at once — allow it for toolcubby.com and later runs are silent.
Keep this tab in front while it renders. Pages are drawn with the browser's animation frame loop, which browsers pause in hidden or background tabs, so a long run started in a background tab can look stalled until you return to it.
Keep the original PDF. The images are new files; the PDF on your disk is never modified, so a wrong setting costs nothing but a reload.

FAQ

Are my PDFs uploaded to a server?

No. The PDF is read from your disk by your own browser, the pages are drawn on a canvas on your device, and the JPG or PNG files are created there too. Nothing is uploaded, no copy of the document is stored, and there is no server that could keep one.

Which pages can I convert?

Either every page, or a range expression such as 1-3, 7, 10-12. Pages come out in the order you type them, a page listed twice is converted once, and a range that runs past the last page of the file is refused instead of quietly producing a partial set.

What is the difference between JPG and PNG output?

JPG is lossy: the files are much smaller and it is the better choice for photos and scans, but it cannot store transparency and it gives up a little detail every time it is saved. PNG is lossless: text and line art stay crisp, and the file is usually several times larger. Both are made from the same rendered page, so the pixel dimensions are identical either way.

What DPI should I choose?

72 DPI is screen size — the same size a PDF reader shows, and enough for a preview. 150 DPI is a sensible default for slides, chat, email and upload forms. 300 DPI is print quality: an A4 page becomes 2480 × 3508 px, roughly four times the pixels of 150 DPI on each side, so rendering takes longer and the files are much bigger.

What does the quality slider do?

It sets the JPEG compression level between 0.6 and 1.0, where 1.0 keeps the most detail. It applies to JPG only — PNG output ignores it, because PNG is always lossless. Above about 0.9 the difference from 1.0 is hard to see; below about 0.8, artefacts start to show around small text and thin lines.

Does converting a PDF to JPG lose quality?

The page is re-drawn as pixels, so it is never identical to the vector original: text can no longer be selected or searched, and a JPG adds a small amount of compression loss on top of that. Rendering at a higher DPI keeps more detail. The loss comes from the format, not from any hidden re-compression step.

Does this extract the images embedded in my PDF?

No. It renders whole pages, so an embedded photo is re-sampled at the DPI you pick rather than copied out at its original size. If you need the original image bytes, a dedicated PDF image extractor is the right tool — this page cannot do that.

How long does it take, and how many pages can I convert in one run?

Up to 100 pages per run. Pages are rendered one after another, so a three-page document is nearly instant, while a hundred pages at 300 DPI can take a minute or more on a phone. The status line names the page currently being rendered, so you can see the run making progress.

How does the Download all button work?

It clicks each page's own Download link in sequence, one file at a time, with a short pause between them. Your browser may ask for permission to save several files the first time — allow it for toolcubby.com and later runs are silent. No archive is created and no zip library is loaded; each image is saved on its own.

Can I convert a password-protected PDF?

No. A PDF that needs an open password cannot be read by the tool, and the page says so instead of producing blank images. Remove the password in a PDF reader, or print the file to a new PDF, then convert the unlocked copy.

Why did my file fail to load?

The usual reasons are that the file is not really a PDF (a .pdf extension sitting on an image or a text file), that it is damaged or only partly downloaded, or that it is password-protected. Open it in a PDF reader first — if it opens there, reload this page and try again.

Is this PDF to JPG converter free, and does it work on mobile?

It is free, with no signup, no watermark and no daily counter. It runs in the browser on desktop, iOS and Android, and the download links behave the same way on every platform. Phones render large pages more slowly, so keep the screen awake for long jobs.
