Why convert HEIC to PNG?

iPhones save photos as HEIC by default. On Apple devices you never notice. Elsewhere you do: on Windows, a .heic file only opens after you install two Microsoft Store add-ons — HEIF Image Extensions and HEVC Video Extensions. Many upload forms, older editors and online tools reject HEIC outright.

PNG opens everywhere — every browser, every operating system and every image editor, with nothing to install.

PNG is lossless, so it keeps all the detail the HEIC holds. The trade-off is size: PNG files are much bigger than HEIC. If you just need a photo that opens anywhere and a smaller file matters, HEIC to JPG is the better pick.

Common reasons to convert HEIC to PNG:

  • ›A website or portal rejects your iPhone photo
  • ›Editing a photo in an app that can't open HEIC
  • ›Sending photos to someone on Windows or Android
  • ›Keeping full detail for editing, where JPG would add compression

Quality & file size: HEIC to PNG

The PNG keeps the photo's full resolution. In our test, a 4032 × 3024 (12-megapixel) iPhone-size HEIC came out as a 4032 × 3024 PNG in about 3 seconds.

PNG is lossless, so no new compression is added. It can't add back detail that HEIC compression already removed.

Expect a much bigger file. In the same test, a 326 KB HEIC became a 7.9 MB PNG. Photos with more texture and fine detail get even bigger. If size matters, convert HEIC to JPG instead.

On the free tier, PNG output has a repeating formatdrop.com watermark. Pro output doesn't.

Frequently asked questions

How do I convert HEIC to PNG on Windows 11?
Open this page in Edge or Chrome and drop the HEIC file — the PNG downloads straight away, with no Microsoft Store extensions needed. Windows itself can only open HEIC after you add HEIF Image Extensions and HEVC Video Extensions.
How do I convert HEIC to PNG on a Mac?
Drop the file on this page, or use Preview: open the HEIC, choose File > Export, and pick PNG from the Format menu.
Can I convert a lot of HEIC photos to PNG at once?
You can drop several at once. The free tier converts 2 files per day; Pro converts any number, up to 500 MB each. For thousands of photos, a desktop tool is faster.
Should I convert HEIC to PNG or JPG?
Choose PNG if you want no extra compression, for editing or archiving — the file will be large. Choose JPG for sharing and uploads — it's far smaller and looks the same for normal viewing.
Why does my iPhone save photos as HEIC?
HEIC is the default High Efficiency format. Apple says it compresses better than JPEG, so photos take less storage. To shoot JPEG instead, go to Settings > Camera > Formats and choose Most Compatible.
Will the PNG be the same resolution as my photo?
Yes. A 12-megapixel iPhone photo becomes a 12-megapixel PNG — nothing is resized or cropped.
Does the PNG keep the photo's date and location?
No. The photo is redrawn pixel by pixel, so metadata such as the date taken, camera model and GPS location is left out. That's useful if you're sharing a photo and don't want to reveal where it was taken. Keep the original HEIC if you need that information.
What happens to a Live Photo?
You get the still photo. A Live Photo's motion and sound are stored in a separate video file, not inside the HEIC, so converting the HEIC gives you a normal PNG.
Is my photo uploaded to your server?
No. The conversion runs inside your browser. Your photos never leave your device.

Your HEIC file never leaves this tab — FormatDrop has no endpoint that receives file data. How it works
