When PNG is the right choice
image editors, design tools, slide software, and systems that specifically require a PNG file.
Start with a sensible output
PNG is lossless but can be very large for photographs. Use HEIC to JPG instead when a smaller sharing copy is the priority.
HEIC compared with PNG
The conversion creates a broadly readable file but cannot add detail beyond the HEIC source. FLUX does not preserve EXIF, IPTC, location, or camera metadata.
What FLUX actually changes
FLUX first asks the browser to decode HEIC. If that fails, its HEIC module may create an intermediate JPEG before Canvas writes the PNG, so alpha transparency is not guaranteed.
Your file stays with your browser
FLUX does not send selected files to its own conversion server. Processing is handled locally on your device, while versioned conversion modules may be loaded securely when needed.
- No conversion-server upload
- No watermark added
- No account required
Before you start
Images are decoded and exported through Canvas on your device. EXIF and IPTC metadata are not copied to the result. Extremely large pixel dimensions can exceed a browser's available memory.
