Why Choose Lossless PNG for Your HEIC Images?
Portable Network Graphics (PNG) is the premier format when visual quality cannot be compromised. While lossy formats discard high-frequency image data to save disk space, PNG retains 100% of the pixel information decoded from your iPhone camera sensor. This makes PNG the best choice for photos you plan to crop, retouch, color-grade, or archive.

Frequently Asked Questions About HEIC to PNG
Why convert HEIC to PNG instead of JPG?
PNG uses lossless compression (DEFLATE algorithm), which means every single pixel from your original HEIC capture is preserved without compression artifacts or pixel degradation. It is the preferred format for digital art, photo editing in Photoshop or Figma, and graphics where precision is paramount.
Is this HEIC to PNG conversion completely private?
Yes. Unlike other web converters that require uploading your photos to third-party cloud servers, our converter runs 100% client-side in your browser via compiled WebAssembly. Your pictures never leave your computer or phone.
Will converting HEIC to PNG result in larger file sizes?
Yes. Because PNG is a lossless format that does not discard fine details, PNG files are typically 3x to 5x larger than compressed JPEGs. This guarantees maximum visual fidelity for editing and archival purposes.
Can I convert multiple HEIC files to PNG at once?
Absolutely. Select or drop dozens of HEIC files into the converter. Multi-threaded Web Workers decode and convert your images in parallel, allowing you to download all converted PNGs in a single ZIP file.
Are EXIF camera details and date stamps preserved in PNG?
Yes. When 'Keep photo details' is checked, our engine extracts original EXIF metadata (camera make, model, shutter speed, date, and GPS coordinates) and injects it into the standard eXIf chunk of each PNG file.
