Convert HEIC to PNG

HEIC (High Efficiency Image Container) is the default photo format on iPhone since iOS 11 — it stores photos at roughly half the size of JPEG, which is why Apple chose it. The catch is compatibility: Windows Photo Viewer, older Android devices, many web forms, and most design tools either can't open HEIC or need codec packs. Converting HEIC to PNG produces a lossless, universally-supported file that opens everywhere and survives future editing without quality loss. This converter decodes HEIC directly in your browser using the heic2any library (loaded on demand, ~1.5 MB, cached after first use), then re-encodes to PNG via Canvas — your photos never leave the device. That local processing matters for HEIC more than most formats: iPhone libraries are exactly the personal, irreplaceable content you don't want bulk-uploaded to a random converter site. If you need smaller files instead of lossless quality, convert to JPG; if you need web-optimized modern files, convert to WebP.

• 1PNG opens everywhere — Windows 10/11 without codecs, older Androids, web upload forms, and every design tool. HEIC does not.
• 2Lossless output preserves your iPhone photo exactly as captured — no second generation of compression artifacts.
• 3Everything is processed on-device via WebAssembly-powered HEIC decoding. Personal photos never touch a server.
• 4No app install, no iTunes sync, no cloud round-trip. The converter works on any device with a browser — including the iPhone itself.
• 5Free and unlimited — batch-convert a weekend's worth of photos without hitting a paywall or watermark.
• 6HEIC's 10-bit color is decoded and mapped cleanly to PNG's 24-bit RGB, avoiding the banding cheap converters introduce.
