What to expect

Real conversion.
Clear limits.

Readable inputs

Chrome and Edge can normally decode JPG, PNG, WebP, AVIF, GIF, BMP, and SVG. Support can vary by browser version and operating system. HEIC, RAW camera formats, Photoshop files, and other specialist formats are not accepted in this release.

Available outputs

JPG
Smaller photographic files with adjustable quality. Transparency is replaced with your selected background colour.
PNG
Lossless pixels and transparency support. Files can be significantly larger for photographs.
WebP
Efficient modern output with adjustable quality and transparency support.
BMP
Uncompressed 24-bit bitmap output for older and specialist software.
TIFF
Uncompressed RGBA output with transparency for editing and archival workflows.
ICO
A PNG-based Windows icon up to 256 × 256 pixels.
Static GIF
One 256-colour frame with simple transparency. Animation is not preserved.
PPM
A simple uncompressed RGB pixmap for technical and development workflows.

Animation and vectors

Animated GIF input is converted as one still frame rather than a full animation. SVG input is rasterised at its intrinsic dimensions, so the downloaded JPG, PNG, or WebP is no longer a vector file.

Conversion cannot create missing detail.

Increasing dimensions changes the pixel grid but does not restore resolution that was absent from the source.
