Methodology & calculation rule
Decode HEVC/HEIF container → Export raw RGBA raster bitmap via Deflate lossless compression
PNG stores uncompressed or Deflate-compressed raster pixel grids. Output files can be considerably larger than the source HEIC.
All image processing executes client-side within your browser sandbox via HTML5 Canvas and WebAssembly. No photographs, bitmaps, or metadata are ever uploaded to remote servers.
Output files are generated in-memory as local object URLs. Files must be smaller than 20 MB and under 24 megapixels.
Real-World Context & Technical Standards
Preserving Decoded Bitmap Fidelity
Exporting decoded HEIC stills to PNG stores raw decompressed raster pixels with lossless Deflate compression, avoiding double-compression lossy artifacts when preparing photos for graphic design or asset libraries.
Desktop Publishing & Print Workflows
Professional page layout software and documentation generators frequently mandate PNG or TIFF assets to guarantee deterministic rasterization without chroma subsampling softening.
File Size Expansion Characteristics
Because photographic imagery possesses high spatial entropy, lossless PNG encoding of a 12 MP camera snapshot can produce a file 3 to 6 times larger in byte size than the original compressed HEIC container.

Frequently Asked Questions
Does PNG improve the quality of a HEIC photo?
No. PNG losslessly captures the already-decoded pixels; it cannot magically reconstruct detail discarded by the iPhone camera sensor.
Can I upload this PNG to design tools?
Yes. PNG is universally recognized across all desktop publishing, raster graphics, and CAD software.
