Private image conversion
Convert HEIC to PNG
Create PNG files from HEIC images entirely in your browser. Use this target when editability, crisp edges, or transparency-friendly workflows matter more than small file size.

PNG is a lossless raster format, so it is useful when the next step is editing, compositing, screenshots, UI assets, or image review where repeated lossy saves would be a problem. It is also the safer interchange format for transparency-aware workflows, even though many iPhone HEIC camera photos are ordinary opaque photographs.
The tradeoff is size. A PNG made from a photo can be much larger than a JPG from the same HEIC source because PNG does not use photo-oriented lossy compression. If you only need to upload or share a camera photo, JPG is usually the smaller and more compatible target. Choose PNG when preserving exact decoded pixels is worth the extra bytes.
Conversion still happens locally: the HEIC is decoded in a worker, drawn to an OffscreenCanvas, encoded as PNG, and exposed as a browser blob download. Large images are checked against the same decoded-memory budget before the page commits to processing them.
Does this upload my files?
No. Everything on this page runs locally in your browser, so your files are never uploaded to a server. Close the tab and nothing is left behind. It even keeps working if you go offline after the page loads.

FAQ
When is PNG better than JPG for a HEIC file?
PNG is better when you plan to edit the result, need lossless pixels, or want a transparency-friendly format for design and compositing tools.
Will HEIC to PNG make smaller files?
Usually no. PNG output from photos is often much larger than JPG output because PNG keeps lossless pixel data instead of using lossy photo compression.
Does PNG output add transparency to iPhone photos?
No. The converter preserves the decoded pixels from the source image. PNG supports transparency, but it cannot invent transparent areas that are not present in the source.
Is HEIC to PNG conversion private?
Yes. The image is decoded and encoded in the browser worker, then downloaded from a local blob URL without sending the file to a server.
