Convert HEIF to PNG Online — Free & Private
Get lossless PNG files from your HEIF images. All processing happens in your browser — nothing gets uploaded.
How to Convert HEIF to PNG
Converting HEIF to PNG preserves full image quality with zero compression artifacts. Three simple steps, no software needed.
- 1
Add your HEIF files
Drag and drop your HEIF or HEIC files into the converter above, or click to browse. Both .heif and .heic extensions are accepted — they're the same format.
- 2
Automatic lossless conversion
Each file is decoded using a WebAssembly engine and re-encoded as PNG directly in your browser. PNG is lossless, so every pixel of detail is preserved.
- 3
Download your PNG files
Click download next to each file, or use 'Download All as ZIP' for batch results. Your PNG files are ready for editing, printing, or archival.
What's the Difference Between HEIF and HEIC?
HEIF (High Efficiency Image Format) and HEIC (High Efficiency Image Container) are essentially the same thing. HEIC is Apple's specific implementation of the HEIF standard, used by iPhones and iPads. Files with either .heif or .heic extension can be converted with this tool.
Converting to PNG gives you lossless quality with universal compatibility. PNG files open on any device, in any image editor, and in any browser — without the compatibility issues that HEIF/HEIC files can cause on Windows and older software.
PNG is the ideal choice when you plan to edit the image further, need transparency support, or want to preserve maximum quality for archival purposes. For smaller files where some quality loss is acceptable, consider converting to JPG instead.
100% Private HEIF to PNG Conversion
Every conversion happens locally in your browser using WebAssembly. Your images are never uploaded to any server. No account required, no data stored, no tracking of your files.
Close the tab and all processed data is gone.
How HEIF to PNG Conversion Works
This converter uses libheif compiled to WebAssembly to decode HEIF/HEIC files. The decoded pixel data is rendered to an HTML5 Canvas and exported as PNG using the browser's native Canvas API.
PNG output uses maximum compression to minimize file size without any quality loss. Color depth from the original HEIF file is preserved at 8-bit per channel (24-bit RGB or 32-bit RGBA with transparency).
The entire process runs client-side. No files are uploaded to any server. The WASM engine handles both HEIF and HEIC container formats identically.
