What this tool does
Converts a HEIC or HEIF photo — the format iPhones save by default — to WebP by decoding it with a WebAssembly build of libheif and re-encoding the result as WebP, entirely inside your browser.
How to use it
Drop or select one HEIC/HEIF file. The tool checks the file's actual bytes to confirm it's really HEIC/HEIF, then decodes and converts it; a ready-to-download WebP appears within a second or two for a typical phone photo.
Worked example
Upload IMG_6034.heic (3.5 MB) and you get IMG_6034.webp ready to download — same pixel content, re-encoded at 92% WebP quality.
Why convert to WebP
WebP typically produces smaller files than JPG at similar visual quality, which is useful when you're uploading the photo to a website, app or CMS that benefits from smaller image sizes and already supports WebP.
What changes technically
The HEIC bitstream is decoded to raw pixels and re-encoded as WebP at a fixed 92% quality; only the first image in the file is used, so multi-image HEIC containers such as Live Photos or burst shots only convert their primary frame. If the uploaded file's contents don't actually look like HEIC/HEIF, conversion is stopped with a clear message instead of guessing.
Limitations
Only one file can be converted at a time — there's no batch mode. Some older desktop software and a few social platforms still expect JPG rather than WebP, so check the destination if you're unsure.
Scope, sources and privacy
Decoding uses a WebAssembly build of the open-source libheif library, matching the HEIF/HEVC image format. Conversion runs entirely in your browser; your photo is never uploaded to a server.
Frequently Asked Questions
- Why convert HEIC to WebP instead of JPG?
- WebP typically produces smaller files than JPG at similar visual quality, which helps if you're uploading the photo to a website or app that benefits from smaller image sizes.
- Is my photo uploaded to a server?
- No — the HEIC file is decoded and converted entirely in your browser using WebAssembly. It never leaves your device.
- Will every app accept the WebP file?
- All modern browsers display WebP, but some older desktop software and a few social platforms still expect JPG — check the destination before relying on WebP everywhere.
