When to convert HEIC to PNG
Graphic design and photo editing workflows
When you need to bring iPhone photos into Photoshop, Figma, or Sketch, PNG ensures no quality loss during the editing process. Every pixel stays intact.
Documentation and technical screenshots
iPhone screenshots in HEIC need to be converted to PNG for technical documentation, bug reports, and UI reviews where sharp text rendering is critical.
Archiving photos at maximum quality
For long-term archival, PNG's lossless compression ensures your photos remain at full quality. No generation loss from repeated edits or conversions.
Extracting subjects with transparency
When using portrait mode photos or extracting subjects in editing software, PNG supports transparency so you can place subjects on any background.

How do I convert HEIC to PNG on Mac?
Open Picmal, drag your HEIC files into the window, select PNG as the output format, and click Convert. The conversion is lossless, every detail from the original HEIC is preserved in the PNG.
Does converting HEIC to PNG lose any quality?
No. PNG uses lossless compression, so your converted files retain 100% of the original quality. This makes HEIC to PNG ideal when you need pixel-perfect images for editing or archival.
Why choose PNG over JPG when converting from HEIC?
Choose PNG when you need lossless quality (no compression artifacts), transparency support, or sharp edges for text and graphics. Choose JPG when you want smaller files for sharing and web uploads where slight quality loss is acceptable.
Will PNG files be larger than the original HEIC?
Yes, 3-4 times larger for photos. HEIC uses advanced compression while PNG is lossless, so a 2.4MB photo from a 12MP iPhone becomes about 9.8MB as PNG. In return you get every pixel, in a format any editor opens.
Can I batch convert HEIC to PNG?
Yes. Drag entire folders into Picmal and convert all HEIC files to PNG at once. 200 iPhone photos take about 3 minutes on Apple Silicon.
When should I use HEIC to PNG vs HEIC to JPG?
Use HEIC to PNG for graphic design work, documentation screenshots, images with text overlays, or when you'll edit the image further. Use HEIC to JPG for general photo sharing, email, and web uploads where file size matters more than perfect quality.
