HEIC to WebP Converter
Convert High Efficiency Image Container (HEIC) files to WebP right in your browser. Free, unlimited batch, and your photos never leave your device.
Your files never leave your device — conversion runs locally in your browser.
To convert HEIC to WebP, drop your iPhone photos above — decoding and encoding both run in your browser, with no upload. WebP keeps the alpha channel and lands noticeably smaller than JPG at the same quality setting. HDR gain maps are not carried over, and EXIF isn't written into WebP output.
Honest limits
- Converts from HEIC only — this site can't create HEIC files.
- HDR gain maps are ignored; output is standard SDR.
- EXIF metadata isn't carried into WebP files.
Need more than a browser can do? Desktop browsers go further than phones — and Media Moana converts at scale on hosted infrastructure.
How it works
Drop your files
Drag HEIC files into the drop zone, click to browse, or paste from the clipboard. Whole folders work too.
Convert locally
Each file is decoded and re-encoded to WebP right in your browser — no upload, no queue. Adjust quality or size first if you like.
Download
Save converted files one by one, or download the whole batch as a ZIP. Originals stay untouched on your device.
About the formats
HEIC — High Efficiency Image Container
HEIC (High Efficiency Image Container) is the format iPhones and iPads have used by default since iOS 11. It compresses photos with the HEVC video codec, producing files roughly half the size of an equivalent JPEG at the same quality. The catch: many websites, Windows apps, upload forms and older software still refuse HEIC files, which is why converting to JPG or PNG remains so common.
WebP — WebP
WebP is Google's web image format, supporting both lossy and lossless compression plus transparency and animation. It typically produces files 25–35% smaller than JPEG at the same quality, which is why so many websites serve it — and why images saved from the web often arrive as .webp files that desktop software and upload forms reject.
Frequently asked questions
Is this safe? Do my photos get uploaded?
No upload happens — ever. Converting HEIC to WebP runs entirely inside your browser using WebAssembly. Your files never leave your device, nothing is stored on any server, and the tool even keeps working if you go offline after the page loads. That's also why there are no file size limits, no queues and no sign-up.
Does converting HEIC to WebP lose quality?
WebP uses lossy compression, so technically yes — but at the default quality setting the difference is invisible for normal viewing and printing. You control the quality slider: higher values mean larger, more faithful files. Your original HEIC files are never modified.
Can I convert multiple HEIC files at once?
Yes — drop in as many files as you like. Because conversion happens on your own computer instead of a server, there is no per-file fee, no daily cap and no waiting in line. Files are processed one after another, and you can download each WebP file as it finishes or grab the whole batch as a single ZIP.
Will HDR iPhone photos look different in WebP?
Slightly, on HDR screens. iPhones store HDR as a gain map riding alongside a regular image; the WebP output keeps the regular (SDR) rendering and drops the gain map, so the photo looks like the standard version of itself rather than the extra-bright HDR preview. Resolution and detail are untouched.
Is there a file size or quantity limit?
There is no hard limit. Server-based converters cap uploads because your files consume their bandwidth and CPU; here converting HEIC to WebP happens on your machine, so the only practical limit is your device's memory. Desktop browsers comfortably handle very large files and big batches.
