What is it

HEIC to PNG 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. PNG output is lossless, but original metadata is not preserved.

PNG blob = canvas.toBlob(HEIC bitmap)

How to use

1Choose a HEIC image file.
2Convert to lossless PNG output.
3Press Convert to PNG.
4Check the preview and file size, then download the result.

FAQ

Is the HEIC file uploaded to a server?

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

Does the PNG 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.
