Convert HEIC to WebP
Convert a HEIC photo to WebP — a modern format that's almost as well-supported as JPG with much smaller files. Great for websites, faster uploads, and storage. Runs entirely in your browser, no upload.
-
Stays on your device
Your photo is decoded and re-encoded entirely in your browser tab. No upload, no server, no log. The file never touches our infrastructure.
-
Works on Windows and Android
HEIC is the Apple-only format that won't open on most non-Apple devices. After conversion, your photo is WebP — readable on any operating system, every photo viewer, every web upload.
-
HEIC → WebP specifics
WebP is widely supported (every major browser since 2020) and produces files even smaller than HEIC in some cases. Great when you want a non-Apple format that's still compact and modern.
How it works
- 1
Drop your HEIC photo
Drag the file onto the box above, or click to browse. If it's on your phone, tap the box and pick the photo from your camera roll.
- 2
Wait for the decoder (first time only)
The HEIC decoder is about 3MB and downloads once. Subsequent conversions on this device skip this step entirely.
- 3
Click and save
The WebP file lands in your downloads folder with the right extension. Open it anywhere — Windows, Android, web upload, email attachment.
Frequently asked questions
Does my photo ever leave my device?
No. Decoding and re-encoding both happen in your browser. There's no upload, no server, no log. Open DevTools while it runs and watch the Network tab — you'll see the decoder library load once, then zero traffic carrying your photo.
Why does my iPhone save photos as HEIC?
Since iOS 11, iPhones default to HEIC because it stores photos at roughly half the file size of JPG with the same visual quality. The downside: only Apple devices and a few newer Windows/Android setups can open HEIC natively. Converting to JPG, PNG, or WebP gives you something every device can handle.
Can I change iOS to save JPG directly?
Yes — Settings → Camera → Formats → Most Compatible. That makes new photos save as JPG instead of HEIC, at the cost of larger files. For existing photos already in HEIC, you'll still need a converter like this one.
What about Live Photos?
Apple Live Photos are stored as a HEIC still plus a short MOV video. This converter extracts the still image and converts it to your chosen format; the video portion isn't included in the output.
Why is the decoder so large?
HEIC uses sophisticated compression (HEVC video codec applied to images), and the decoder is the same code Apple ships compiled to WebAssembly. It's about 3MB, downloaded once and cached. After the first conversion on this device, the rest are nearly instant.
Does this work on mobile?
Yes. Tap the drop zone to open the photo picker, pick a HEIC, tap save when done. On iPhone you can also share a HEIC directly into the browser to convert it.
How does WebP compare to JPG for HEIC conversion?
WebP typically produces files 20-35% smaller than JPG at the same visual quality. Both are widely supported — JPG by literally everything, WebP by every major browser and most modern software. Pick WebP for web use and modern workflows; pick JPG if you need maximum compatibility (legacy software, some older platforms).
Does WebP work in image-editing software?
Modern versions of Photoshop, Affinity Photo, GIMP, and most other major editors support WebP. A handful of older or specialized tools don't yet — if you hit one, convert to PNG for a universal lossless format or JPG for a universal lossy one.
Is WebP a good choice for photos I'll keep long-term?
For archival, PNG (lossless) is the gold standard if storage isn't a concern. WebP is a great practical balance — small files at high quality, with browser support that's only going to improve. JPG is the safest long-term bet for absolute compatibility with future tools.
