About HEIF and PNG

HEIF containers are decoded with libheif, the same engine used by most desktop HEIF tooling.

PNG output is lossless and keeps the alpha channel intact.

HEIF files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.

Limitations

  • HEIC is decoded with libheif; multi-frame HEIF sequences use the first image.

Frequently asked questions

How do I convert a HEIF file to PNG?

Add your HEIF file to the box above. convertexa detects the format from the file content, applies the HEIF to PNG conversion and gives you the result to download. The whole operation runs inside your browser.

Are my HEIF files uploaded anywhere?

No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.

Is the HEIF to PNG conversion lossless?

Yes. This conversion preserves all of the source data, so the PNG file is equivalent to the original HEIF file.

Is there a size limit?

For reliable results keep the input under 40 MB. Very large files run out of memory in the browser rather than failing quietly.

Which browsers are supported?

Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
