HEIC to WebP Converter
Convert HEIC photos from your iPhone to WebP in the browser. Usually 25-35% smaller than JPG with transparency support - no upload, no signup.

HEIC is what an iPhone writes by default. It holds noticeably more detail than JPEG at the same file size, because it uses a newer compression method and a higher bit depth - but almost nothing outside Apple's ecosystem opens it, which is why the format causes so much friction when a photo leaves the phone.
Converting to WebP keeps most of that quality in a format every current browser can display, and usually saves another 25-35% compared with JPG at the same visible quality. Unlike JPG it can also store transparency. The catch is compatibility: some older desktop software still will not open WebP, so if the image is going to a printer or an upload form that only accepts JPG, convert to JPG instead. Both are lossy formats, so convert from the original HEIC rather than from a copy that has already been converted once.
How to convert HEIC to WebP
Drop your HEIC or HEIF files onto the page, or click to browse. Several files can be converted at once.
The output is already set to WebP. Adjust the quality if you need a smaller file; 80-90% is visually identical for most photos.
Convert and download the results individually or as a single ZIP.
FAQ
Why is WebP smaller than JPG here?
WebP uses a more efficient compression method, so at the same visible quality it typically produces files 25-35% smaller than JPEG. It also supports transparency and both lossy and lossless modes, which JPEG cannot.
Does converting lose quality?
Some, because WebP in lossy mode discards detail the same way JPEG does. At 80-90% quality most photographs look identical on screen. Convert from the original HEIC rather than from an already-converted copy, since every lossy save compounds the loss.
What about Live Photos and HEVC video?
Neither is supported. A Live Photo is a still image plus a short video, and this tool converts the still only - the motion part is lost. HEVC video files are a different format entirely and are not image conversions.
Are all my HEIC files supported?
Standard single-image HEIC and HEIF files are. The decoder reads the primary image; depth maps, HDR gain maps and multi-image containers are ignored rather than converted. On Apple devices the browser decodes natively and no extra download is needed; elsewhere a small decoder is fetched once and then cached.
Can WebP store transparency?
Yes, both lossy and lossless WebP support an alpha channel, so a HEIC image with transparency keeps it. That is one advantage over converting to JPG, which has to fill transparent areas with white.
Do my photos leave my device?
No. The decoding and encoding both happen inside your browser, so the images are never uploaded and there is no server-side size limit.

Choosing between JPG, PNG, WebP and AVIF
These formats solve different problems, and picking the wrong one costs you either quality or file size. JPG is the safest choice for photographs and for anything you need to send to someone else, because every device and program opens it - but it is lossy and has no transparency. PNG is lossless and supports transparency, which makes it right for logos, screenshots, diagrams and anything with sharp edges or text, at the cost of a much larger file. WebP typically beats JPG by 25-35% at the same visible quality and supports transparency, but a few older programs still cannot open it. AVIF compresses even further, especially at low quality settings, but encoding is slower and support is the newest of the four. A practical rule: JPG to send, PNG to edit, WebP for your own website, AVIF when every kilobyte counts and you have checked that your audience can open it.
How much quality you actually lose
Lossy compression throws away detail your eye is least likely to notice - first fine texture, then edges. In practice most photographs look identical to the original down to roughly 75-80% quality, and differences only become obvious around faces, hair, foliage, fabric patterns and text. That is why a portrait and a screenshot need different settings: a face at 60% shows blotchy skin where a landscape at 60% still looks fine. Resizing matters more than quality for perceived sharpness: halving the pixel dimensions usually saves far more than dropping quality from 90 to 60, and the result looks better. If you need a specific file size, reduce dimensions first, then quality, and stop as soon as you hit the target rather than going lower than necessary.
