The PNG Guide
When quality matters more than file size, professionals choose PNG. Unlike JPG which compresses images, PNG is a 'lossless' format that preserves every single pixel of your original iPhone photo. This makes it the ideal choice for graphic designers, photographers, and editors who need to edit their assets in Photoshop or Canva without introducing compression artifacts.
Why is the file size larger?
HEIC is compressed; PNG is uncompressed. A 2MB HEIC file might become a 10MB PNG. You are trading storage space for absolute image perfection.
Transparency Support
If your HEIC file has a transparent background (like a sticker or cutout), converting to PNG preserves that transparency. JPG would turn it white.
16-Bit Color Depth
iPhones capture wide-gamut color. Our PNG engine respects these profiles, ensuring your vibrant sunsets and neon shots don't look washed out.
Technical Spec
Where does PNG work?
Adobe Photoshop
Editing JPGs can cause 'generation loss'. PNG is stable and robust, allowing you to save and resave edits without degrading quality.
Web Design
For logos, screenshots, and UI elements, PNG provides crisp lines that JPG compression often blurs. Essential for web developers.
4K Monitors
On high-density Retina displays, JPG artifacts can be visible. PNG conversion ensures your photography looks perfectly smooth.
Marketing Tools
Some email tools and CMS platforms don't support HEIC. PNG is the highest quality alternative for uploading assets.
Native WASM Processing
FastHEIC uses WebAssembly to run the conversion engine directly on your hardware. This ensures your private photos never leave your device RAM.
