Here is the short version — XPM is a raster image format with its own balance of compression, colour depth, and software support. Hence the need for AVIF. Need a AVIF for a CMS, a chat message or an email client that politely refuses XPM? This tool re-encodes your image in the background and returns a drop-in AVIF replacement. No registration, no watermark, no visual change beyond what the AVIF encoder itself introduces. Keep in mind XPM is a raster image format with its own balance of compression, colour depth, and software support. And remember that AVIF is the AV1-based next-gen image codec, extremely efficient with full HDR and alpha support.
X PixMap
Source formatXPM (X PixMap) is a color image format for the X Window System that stores pixel data as ASCII text with a color palette. Unlike XBM, it supports full color and transparency through a simple text-based representation.
AVIF Image
Target formatAVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining excellent visual quality, including HDR and wide color gamut support.
Why convert XPM to AVIF
Converting keeps the picture recognisable end-to-end while changing the container that ships it. AVIF typically wins on one of three fronts: broader software support, smaller files for the same visual quality, or features like transparency that XPM cannot express. The conversion itself is fast because both sides are raster formats.
HOW TO CONVERT
XPM → AVIF
Upload your XPM
Start by dropping the XPM onto the uploader. Files up to 100 MB go through on the free tier without registration.
Conversion happens server-side
Our imagemagick-based pipeline reads the XPM pixel grid, preserves resolution and colour profile, and encodes a clean AVIF.

Common Use Cases
Cross-platform previews
Windows, macOS and Linux file browsers all render AVIF thumbnails; XPM support varies by OS version.
Mobile galleries
iOS Photos, Google Photos and Samsung Gallery index AVIF instantly — XPM sometimes falls back to a generic file icon.
Stock photography uploads
Shutterstock, Adobe Stock and similar marketplaces require AVIF in their contributor guidelines.
Archive migration
Converting legacy XPM archives to AVIF future-proofs the collection against declining codec support.
Quality & Compatibility
Converting keeps resolution, aspect ratio and colour profile identical to the source. Metadata (EXIF, XMP) transfers where AVIF supports it; otherwise it is dropped. If the XPM contained an alpha channel and AVIF does not support transparency, the background is flattened to white by default.
Tips for Best Results
- When uploading to Retina / high-DPI contexts, render the AVIF at 2× the CSS pixel size; the crispness gap over 1× is noticeable on modern screens.
- Strip EXIF metadata from the AVIF before publishing if the XPM came from a phone camera — it often contains GPS coordinates and device IDs.
- If the XPM is a screenshot of text or UI, prefer a lossless AVIF target to avoid the JPEG-style ringing around glyph edges.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both XPM and AVIF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If AVIF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded XPM exactly, but cannot recover detail that XPM had already compressed away.
Often yes, especially when AVIF is lossless. XPM tuned for efficient web delivery will usually produce smaller files than AVIF's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
