Convert HEIC to PNG

Converts an iPhone photo to lossless PNG, avoiding a second lossy encode.

What to expect

PNG is a poor fit for photographs, so expect a file several times larger than the original HEIC.

Why convert HEIC without uploading

Most online converters take your file, send it to their servers, convert it there and hand back a download link. That means your document sits on someone else's disk, subject to their retention policy and their breaches. It also means you cannot use them offline, and cannot use them at all for anything confidential.

frogConvert does the conversion in the page itself, with ImageMagick compiled to WebAssembly. There is no upload step because there is no server. You can disconnect from the network and it still works.

About the formats

HEIC

Apple's default photo format since iOS 11, storing still images with HEVC video compression at roughly half the size of a comparable JPEG. Patent licensing is why support outside Apple's ecosystem stayed thin. More about HEIC files.

PNG

Lossless compression with full alpha transparency, ideal for screenshots, logos and line art. Photographs stored as PNG are typically several times larger than the equivalent JPEG. More about PNG files.

Common questions

Is my file uploaded when converting HEIC to PNG?

No. The conversion runs entirely in your browser. The file never leaves your device, there is no server to upload to, and the page works offline once loaded.

Is HEIC to PNG conversion free?

Yes, with no account, no watermark and no file limit per day. frogConvert is open source and there is no server cost to recover, because your device does the work.

How large a file can I convert?

Up to 2 GB for a single file, 500 MB total per batch, and 300 files at once. The practical limit is your device's memory, since everything is processed locally.

What is lost converting HEIC to PNG?
