What is it

HEIC to WebP conversion is useful when preparing phone photos, web-optimized images, or app upload assets. HEIC/HEIF uses a dynamically loaded browser codec, while AVIF/WebP/JPG/PNG use Canvas encoding. WebP output can change size and sharpness depending on the quality setting.

WebP blob = canvas.toBlob(HEIC bitmap)

FAQ

Is the HEIC file uploaded to a server?

No. File selection, decoding, conversion, and output file creation happen in the browser.

Does the WebP output keep original metadata?

No. The output is redrawn through Canvas, so metadata such as EXIF is not preserved.

Can browser conversion fail?

Yes. An error is shown when the browser cannot encode the target format or when the image is too large.
