Convert HEIC to PNG online with real compression, not just a bigger file

A plain HEIC to PNG conversion routinely comes back several times larger than the file you uploaded, because PNG is built to reproduce every pixel exactly rather than compress a photograph the way HEIC does. This tool shrinks the result automatically while keeping transparency and color accuracy intact.

Smaller than a plain PNG conversion

A color-palette pass runs automatically, cutting the output by roughly 60–75% depending on the compression level you choose, with an average error under 2% — not visible on a photograph.

Need a lossless file instead?

Turn palette compression off in the settings for a byte-for-byte lossless PNG, at the cost of a larger file.

Transparency is kept, not flattened

Unlike JPG, PNG has a real alpha channel, so transparency from the source HEIC survives untouched instead of being flattened onto a background color.

Colors stay accurate

The same EXIF-orientation correction and Display P3 color handling used for JPG output apply here too, so portraits come out upright and colors don't shift.

What you get

  • Convert one photo or a batch of up to 200 at once
  • A single PNG, or a ZIP that keeps your original filenames
  • Free, with nothing stored for longer than an hour

What's next?

Don't need transparency? HEIC to JPG usually produces a smaller file. Want to squeeze the PNG down further? Compress PNG can help, and Remove Photo Metadata strips the location and device data iPhones embed by default.

Frequently Asked Questions

PNG reproduces every pixel exactly, while HEIC uses heavy, lossy compression — so a PNG is naturally larger even after this tool's automatic palette compression narrows the gap.

Not by default — a palette pass shrinks the file by roughly 60–75% with under 2% average error, invisible on a normal photo. Turn palette compression off for a byte-for-byte lossless PNG instead.
