HEIC to WebP Converter
Turn the iPhone photos that Windows, Android and older apps can't open into small, fast-loading WebP images — privately, in your browser, with no upload and no signup. Drag the quality slider to control the final size.
What is a HEIC to WebP converter?
A HEIC to WebP converter changes an Apple HEIC (or HEIF) image into the web-friendly WebP format. HEIC is the efficient format modern iPhones use to save space while keeping high quality, but many Windows systems, Android devices and older apps cannot open it natively, and most websites prefer not to accept it. WebP is a Google format that every modern browser supports and that compresses better than JPEG or PNG, so a WebP image loads faster while looking nearly identical.
This tool decodes your HEIC file locally using WebAssembly and re-encodes it as WebP on a canvas. A quality slider lets you balance detail against file size. Because it all runs in your browser, nothing is uploaded, so even sensitive screenshots stay private.
It also accepts JPEG, PNG and WebP inputs, so you can still produce a WebP output even when a HEIC variant cannot be decoded by your browser.
How to use the HEIC to WebP converter
- Drag the quality slider to choose how much to compress — 60–80% is a good balance for photos.
- Select one or more HEIC/HEIF photos from your iPhone or computer.
- Each file is decoded to WebP automatically and shown as a preview with its new size.
- Click Download WebP (or the copy button to put the image on your clipboard) and the file is saved to your device.
Example
You select a 4.2 MB HEIC photo from an iPhone. At 75% quality the converter outputs a 920 KB WebP file — roughly 78% smaller — which loads far faster on a website. Dropping the slider to 55% gives a 540 KB file ideal for a mobile page, while 90% keeps more detail for a photo you plan to zoom into.
Who is a HEIC to WebP converter for?
Anyone who has ever tried to open an iPhone photo on a device that is not an Apple product needs a HEIC to WebP converter. It turns Apple's default photo format into a small, universally supported WebP file entirely in your browser, so it helps four groups in particular.
- Photographers: Shooting lots of frames on an iPhone fills a card with HEIC files. When a client gallery, CMS or print shop only accepts standard formats, HEIC to WebP online lets you convert the whole shoot quickly, with no desktop install.
- iPhone users: Your library is full of HEIC because every new photo defaults to it. When you need to email a picture, post it to a site that rejects HEIC, or send it to a friend on HEIC to WebP for Android, this is the fastest route.
- Web developers: Modern builds prefer WebP because it is smaller than JPEG or PNG and supported by every current browser. A tool that can batch convert HEIC files keeps a landing page snappy without a server-side pipeline.
- People freeing up storage: A HEIC to a smaller WebP conversion shrinks each photo, so you can keep more images on your phone or cloud drive — the HEIC to WebP 2024 workflow has become a common alternative to JPEG.
WebP vs JPG vs PNG: what should you output?
All the conversions here run offline, so there are no byte counts to invent — only format facts. The table compares WebP, this tool's output, against the other formats you might pick, plus the original HEIC source file.
| Format | Transparency retained? | Typical size | Best use |
|---|---|---|---|
| WebP (this tool's output) | Yes — lossy or lossless variants | Smallest for photos | Fast-loading web images, thumbnails, CMS uploads |
| JPG | No | Smaller than PNG, usually larger than WebP | Sharing photos when maximum compatibility matters |
| PNG | Yes — fully lossless | Largest of the three for photos | Logos, icons, screenshots that need crisp edges |
| HEIC (source file) | Yes, but rarely used | Smaller than JPEG or PNG at equal quality | Storing photos on an iPhone or in iCloud |
Common use cases
- Uploading iPhone photos to a website, CMS or tool that only accepts standard web formats.
- Shrinking large HEIC photos before sending them over email or messaging apps.
- Preparing fast-loading images, thumbnails or product photos for your website.
- Opening HEIC images on a Windows PC, Android device or browser that can't read them.
Pro tips
- Start at 75–80 % — it keeps photos sharp while cutting the file size dramatically.
- Use a lower quality (around 50–60 %) for thumbnails and icons where small size matters most.
- WebP supports transparency, so it can replace PNG for simple graphics on the web.
FAQ
How do I convert HEIC to WebP?
Pick a quality level, select one or more HEIC photos, and they are converted to WebP instantly in your browser. Download the results when ready.
Why convert HEIC to WebP?
HEIC is Apple's efficient format, but many Windows, Android and web apps cannot open it. WebP is smaller for the same quality and loads faster on the web, making it a great upload format.
Are my photos uploaded anywhere?
No. The conversion runs locally in your browser using WebAssembly and the Canvas API, so your photos never leave your device.
Does converting to WebP lose quality?
WebP uses lossy compression, so a little quality is traded for a much smaller file. Use the quality slider to balance size and fidelity — higher quality gives a larger file.
Can I convert several HEIC files at once?
Yes. Select multiple HEIC files and the tool converts and previews each one, so you can download them one at a time.
Does it need internet?
Yes, once, to load the WebAssembly HEIC library; the actual conversion happens locally on your device.
Why does my HEIC file fail to convert?
Some screenshots, Live Photos or unusual HEIF variants cannot be decoded by the HEIC engine and will not convert. Try saving the photo as JPEG first.
What is the difference between HEIC and WebP?
HEIC is Apple's high-efficiency format used by iPhones for photos. WebP is a Google format that is widely supported across browsers and produces very small, fast-loading images.
Is WebP the best format for website images?
For most sites yes. All modern browsers support WebP and it is much smaller than JPEG or PNG, so pages load faster. Keep PNG for lossless graphics.
Is this converter free and unlimited?
Yes — free, unlimited, no watermark, no signup and no hidden charges.
