HEIC to PNG Converter

Convert iPhone HEIC photos to lossless PNG format. Perfect for editing in Photoshop or archiving with zero quality loss. Works in any modern browser. Free and private.

When to convert HEIC to PNG instead of JPG

Choose PNG when you need a lossless copy of your iPhone photo for professional editing. Unlike JPEG, PNG stores every pixel exactly without compression artifacts - making it ideal as an editing master in Photoshop, Lightroom, or Affinity Photo. PNG also supports transparency, so if you plan to remove the background later, PNG is the right output format.

Browser support for HEIC conversion

HEIC files use the HEVC codec, which is built into macOS and iOS but absent from browsers on Windows and Android. On those platforms this tool loads a small open-source decoder (about 1.3 MB) on demand and decodes the photo on your device, so the conversion works everywhere. Safari decodes HEIC natively and skips the extra download.

HEIC to PNG file size

Expect a significant file size increase: a 3 MB HEIC photo will typically become a 15–30 MB PNG. This is normal - PNG's lossless compression is far less efficient than HEIC's HEVC codec. If file size matters, convert to JPG (92 quality) instead, which produces much smaller output while still providing excellent quality.

Frequently asked questions

PNG provides a lossless copy - no additional quality is lost during conversion. This matters if you plan to edit, re-save, or re-export the image multiple times. JPEG introduces additional compression artifacts each time it's re-encoded. For iPhone photos you want to use as editing masters, HEIC to PNG is the professional choice.
Yes. Windows and Android browsers cannot decode HEIC on their own, so this tool loads a small open-source decoder (about 1.3 MB) the first time you pick a HEIC file and then converts the photo locally. Your file is never uploaded - only the decoder is downloaded, and it is cached for subsequent conversions. Safari on macOS and iOS decodes HEIC natively and skips that download.
Typically 5–10 times larger. HEIC achieves exceptional compression using HEVC technology. A 3 MB HEIC portrait photo might become a 20–30 MB PNG. If file size is a concern, use HEIC to JPG instead (quality 92 produces roughly 2–4 MB output from the same 3 MB HEIC).
No - HEIC already applied lossy compression when the iPhone captured the photo. Converting to PNG creates a lossless copy of the HEIC's current quality, but it cannot recover detail that the original HEIC compression discarded. The PNG will look identical to the HEIC at normal viewing conditions.
