HEIC to PNG converter
Convert HEIC to lossless PNG in your browser. No re-compression, no upload.
Why convert HEIC to PNG
PNG is lossless. Once the HEIC is decoded, every pixel is written out exactly as it was, with no second round of compression. That matters if the image is going into an editor, a design file, or an archive where you will save it again later.
The cost is size. A PNG of a normal photograph is usually three to six times larger than the HEIC it came from, because PNG compression is built for flat colour and sharp edges, not for the noisy detail in a camera sensor. There is no quality setting to trade away — lossless means lossless.
PNG also carries an alpha channel, so it is the right target if you plan to cut out a background afterwards. Note that the converter writes the pixels only, so the shot date and GPS position are not carried over. If you need those kept, convert to JPG instead.
Questions
Does this keep the original photo date?
No. The converter writes the pixels only, so the shot date, GPS position and camera settings are not carried over into the PNG. Convert to JPG instead if you need that information kept.
What if a HEIC file holds more than one image?
Some HEIC files contain several images. Turn on "Extract every frame" and each one is saved as a separate file, numbered in order. With the option off, only the main image is converted. The moving part of a Live Photo is a separate video file, not part of the HEIC, so it is not converted.
Are my photos uploaded anywhere?
No. Decoding runs inside your browser using WebAssembly. The files are read from disk into memory and never sent over the network, which also means conversion speed depends on your own device.
Can I make the converted photos smaller?
Yes. Set "Max size" to limit the longest side, for example to 1920 or 1600 pixels for a website or an email. Photos smaller than the limit are left at their original size.
How many files can I convert at once?
There is no hard limit. Past about 25 files the browser slows down noticeably on phones and older laptops, so you will see a warning, but you can continue.
