HEIC to PNG Converter — Lossless, Bulk, No Upload

Why convert HEIC to PNG instead of JPG

JPG is a lossy format — every re-encode slightly degrades the image. If you're archiving family photos, delivering work to a client, or sending files to a print service, PNG is the safer choice: it's lossless, meaning every pixel in the output is identical to what the decoder read from the HEIC. There's no quality slider, no compression trade-off, and no generation loss if you ever need to re-export later. PNG also preserves full-alpha transparency — useful if you have a photo with a clipped background you want to keep clean.

Why iPhone photos won't open on Windows or Android

Since iOS 11, iPhones default to HEIC (High Efficiency Image Container) instead of JPG. HEIC files are roughly half the size of equivalent-quality JPEGs, but Windows, most Android phones, Slack, Reddit, eBay, Craigslist, and many email clients don't open them natively. Converting to PNG gives you a format every device on earth understands — with zero quality loss. SimpleTool's converter uses a WebAssembly build of libheif (the same C library Apple, Adobe, and Mozilla use) and runs entirely in your browser. Your photos never touch a server.

EXIF & GPS scrub — what gets stripped

Conversion re-encodes pixels through a fresh canvas, which removes the entire EXIF block from every output PNG:

• GPS coordinates — where the photo was taken
• Date / Time / Time Zone — exact capture timestamp
• Camera make, model, serial number — device fingerprint
• Lens model, focal length, aperture, ISO, shutter speed
• Software fingerprint — iOS version and edit history
• Apple-specific tags — Live Photo identifiers, depth-map references

Image orientation is always read from the HEIC and baked into the output pixels, so photos come out upright regardless of how the original was tagged.
