Convert HEIC to PNG

How to convert a HEIC photo

  1. Drop or pick a HEIC or HEIF photo from your iPhone or camera.
  2. PNG is already selected: the output is a lossless copy of your photo.
  3. Convert and save. The photo now opens on any device or app.

Why convert HEIC?

HEIC is the space-saving format iPhones shoot by default — efficient, but most websites, Windows PCs and older apps can't open it. PNG is a lossless format with an alpha channel, pixel-perfect for logos, screenshots and line art.

Converting to PNG gives you a lossless copy of the photo — every pixel preserved exactly. Files come out larger than JPG, so pick PNG when fidelity matters more than size.

OptImg decodes the HEIC right on your device and re-encodes it locally, so your photo is never uploaded — unlike most online HEIC converters, which send every image to their servers. That's also why there's no queue and no size limit beyond your device's memory.

Frequently asked questions

Are my iPhone photos uploaded to a server?
No. The HEIC-to-PNG conversion runs entirely in your browser: your photo never leaves your device, there's no queue, and no size limit beyond your device's memory.
Why won't my HEIC photos open in the first place?
HEIC is Apple's default camera format, and most browsers, Windows PCs and older apps can't open it, largely for licensing reasons. Converting to PNG fixes that for good — this tool brings its own HEIC support, so it works in any modern browser.
Will converting HEIC to PNG lose quality?
No. PNG is lossless, so every pixel the decoder reads is preserved exactly. The file will be considerably larger than the HEIC — that's the price of a lossless copy.
Is the HEIC to PNG converter free?
Yes: completely free, with no signup, no watermark and no cap on how many photos you convert. There's nothing to install; it runs in your browser.
