About HEIC to PNG
PNG is a good target when you want to edit a HEIC photo further, add it to a design, or keep a copy that won't lose detail each time it's saved. Unlike JPG, PNG compression is lossless, so the converted file keeps every pixel the HEIC decoder produces. The catch is size: a PNG of a phone photo is often several times larger than the HEIC it came from. This tool converts one file or a batch, lets you cap the dimensions to keep files manageable, and bundles the results into a single ZIP when you're done.
How to Use It
- 01
Add HEIC files
Drag your .heic or .heif images into the box, or tap it to choose them.
- 02
Optionally resize
Enter a maximum width or height to keep PNG files smaller. Leave blank to keep the full size.
- 03
Convert and save
Press Convert, then download each PNG or grab them all in one ZIP.
HEIC to PNG: when lossless matters
PNG is lossless: it stores every pixel exactly, so no detail is lost when you save, open and save again. That makes it the right choice when you'll edit an iPhone photo in Photoshop, GIMP, Canva or Figma, when the image is going into a design or print layout, or when you want an archival copy that won't degrade.
For simply sharing or uploading photos, JPG is smaller and just as widely supported, so use HEIC to JPG for that.
Why the PNG files are large
iPhone photos are typically 12 megapixels (4032 × 3024) or more, and a lossless PNG of a 12-megapixel photo is often 15–25 MB, compared with 2–3 MB for the HEIC and 3–5 MB for a 90% JPG. That's expected: lossless compression can't throw away detail to save space the way HEIC and JPG do.
If you don't need full resolution, set a maximum width or height when converting. A maximum width of 2000 pixels makes each PNG about a quarter of the size and is still plenty for most edits and screen use.
PNG vs TIFF for editing
Photographers sometimes ask for TIFF instead of PNG. Both are lossless and work for editing, but PNG is supported more widely, opens in every browser and web app, and its files are usually a little smaller. Unless your print shop or editing workflow specifically asks for TIFF, PNG is the simpler lossless choice for iPhone photos.
What carries over from the HEIC
The photo is decoded and rotated to the orientation it was taken in, so portrait photos stay upright. Colours are converted to standard sRGB so they look right in any app. Extras that HEIC can hold, such as depth maps, Live Photo motion and camera metadata including GPS location, aren't copied into the PNG; keep the original if you need them.
Converting a batch of iPhone photos
Add as many HEIC or HEIF files as you need, from your computer or straight from your phone, and download the PNGs one by one or as a single ZIP. On iPhone, tap the box and choose photos from your library or the Files app.
To make your iPhone save JPG instead of HEIC from now on, go to Settings, Camera, Formats and choose Most Compatible. For documents photographed with your iPhone, HEIC to PDF combines several photos into one PDF.
Questions
Why is the PNG so much bigger than my HEIC file?
HEIC uses lossy compression designed for photos, while PNG stores the image losslessly. For photographs that usually means a larger file. If size matters more than perfect detail, the HEIC to JPG converter will give you much smaller files.
Does PNG make my photo look better?
No. Converting can't add detail that isn't in the original. PNG simply avoids adding any new compression loss, which matters if you'll edit and re-save the image several times.
Is there a quality slider for PNG?
No, because PNG is lossless and has no quality level to choose. You can still reduce the file size by setting a maximum width or height.
Do my files leave my device?
No. Decoding and encoding both happen in your browser. The page has no upload step, and its security policy blocks it from sending data to other websites.
