A Netpbm format with a flexible header describing image depth and tuple type. PAM can represent grayscale, color, and alpha-bearing image data.
Conversion uses the supported raster channels; arbitrary scientific tuple semantics are not interpreted.
PAM file format guideOpen a conversion below or choose the output above. Add up to 100 files and download results separately or in a ZIP.
Choose dimensions and image quality before converting. Still-image exports keep one frame. Unedited GIF, WebP, AVIF, JPEG XL and MNG conversions can retain animation. Animated edits use a GIF intermediate with a limited color palette. Canvas editing uses browser display precision and does not preserve original EXIF, HDR, or scientific image data.
Processing uses your device when possible and our servers when required. Browser files are limited to 256 MB each; server conversions to 64 MB; browser spreadsheets to 32 MB. Previews show supported content and do not guarantee identical rendering in every application.
