Need pixel-perfect iPhone photos for design mockups, documentation, or archival work? PNG stores every decoded pixel losslessly — no second round of compression damage.

100% private. Nothing is uploaded.
HEIC optimizes for storage; PNG optimizes for pixel fidelity
Drag .heic or .heif files straight from your Mac Photos export or AirDrop folder. The converter accepts single shots or full albums.
HEVC is decompressed in-browser to raw pixels. Those pixels are written to PNG using zlib DEFLATE — lossless, no further quality reduction.
Download each PNG individually or grab the whole batch as a zip. Filenames match source; EXIF is embedded as a PNG text chunk.

HEIC is lossy. PNG is lossless. The conversion is one-way: PNG cannot recover detail HEIC discarded during capture, but it guarantees no further loss.
libheif compiled to WebAssembly runs your decode locally
streams one file at a time to avoid tab crashes on large albums
Decoding behavior, transparency, metadata, and edge cases.
PNG encoding itself is lossless — every pixel the HEIC decoder produces lands in the PNG unchanged. But HEIC was already lossy when your iPhone saved it. Think of PNG here as a guarantee against further degradation, not as quality recovery.
iPhone camera HEIC files are solid — no alpha channel. Edited HEIC from apps like Procreate or Affinity Photo can include transparency, and our converter preserves the alpha channel when writing PNG.
A 12 MP iPhone photo is ~2 MB as HEIC but ~15–20 MB as PNG. HEIC uses HEVC block-based prediction; PNG uses generic DEFLATE on raw pixels. Expect 5–10× size increase — normal and unavoidable for lossless output.
The primary frame converts to PNG. The companion .mov video of a Live Photo is ignored. Portrait depth maps and semantic segmentation masks stored in the HEIC's auxiliary images are dropped — PNG has no standard slot for them.
Some newer iPhones capture 10-bit HDR HEIC. Our converter outputs 8-bit PNG by default for maximum compatibility. For 16-bit PNG output, use our dedicated HDR pipeline.
Depends on use. PNG wins for editing, screenshots, documents, design work — anything where you'll re-save, zoom, or composite. JPG wins for sharing, web upload, email — anything where file size matters more than pixel purity.
Yes. Any standards-compliant HEIC produced by Samsung, Pixel, Canon mirrorless cameras, or desktop software (Affinity, ImageMagick) decodes correctly. The HEVC bitstream is identical regardless of source.
ProRAW is actually DNG, not HEIC. For regular 12/48 MP HEIC from the Photos app, the converter handles files up to 50 MB. Very large HEIC containers (burst sequences, long exposures) may need splitting in Photos before upload.
