Every format,
documented.
Pixelmint decodes every entry below. Encoding (output) is currently available for the five marked formats — these are the ones browsers ship native encoders for, plus AVIF and JXL via WebAssembly.
PNG
PNG is a lossless raster format with full alpha transparency. Best for screenshots, logos, and graphics where you can't afford any quality loss.
JPG
JPG (JPEG) is a lossy raster format with excellent compression for photographs. It does not support transparency, so transparent pixels become white.
WebP
WebP is a modern Google-developed format that beats JPG and PNG on file size at the same quality. Supports both lossy and lossless modes plus transparency.
AVIF
AVIF is the newest open image format. It delivers smaller files than WebP at the same quality — often 30-50% smaller than JPG. Supported by all modern browsers.
JPEG XL
JPEG XL (JXL) is a modern royalty-free format with both lossy and lossless modes. It often beats AVIF and WebP on quality at the same file size, with much faster encoding.
GIF
GIF is an 8-bit palette format famous for animation. Pixelmint converts to single-frame GIF using neural color quantization for the best possible 256-color result.
BMP
BMP is an uncompressed 24-bit Windows bitmap format. Files are large but pixel-perfect and trivial for any image library to read.
TIFF
TIFF is a flexible, lossless raster format common in print and archival workflows. Pixelmint emits uncompressed RGBA TIFF.
ICO
ICO is the Windows favicon format. Pixelmint wraps a PNG inside a single-frame ICO container — ideal for browser tabs and desktop shortcuts.
QOI
QOI (Quite OK Image) is a lossless format that decodes 20-50× faster than PNG. Great for engines and tools that need to stream lots of images at runtime.
PDF wraps your image inside a single-page document at its native pixel size. Great for sending raster artwork to print shops, lawyers, and document workflows.
SVG
SVG is a vector format. When converting a raster image to SVG, Pixelmint emits a self-contained SVG with the raster embedded — useful for design tools that only accept SVG.
HEIC
HEIC is Apple's iPhone photo format. Browser decode support is limited; for best results, convert HEIC on a Mac before uploading.
