Convert HEIC to PNG
Convert iPhone HEIC photos to PNG online, free and 100% in your browser. No upload, no signup — get photos that open anywhere in seconds.
How to convert a HEIC photo
- Drop or pick a HEIC or HEIF photo from your iPhone or camera.
- PNG is already selected: the output is a lossless copy of your photo.
- 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.
