AVIF vs XBM — Differences, File Size & When to Use Each

Q: What is an AVIF file?

AVIF (AV1 Image File Format) is a cutting-edge image format derived from the AV1 video codec, backed by the Alliance for Open Media. It delivers up to 50% smaller files than JPEG with equal or better visual quality, plus HDR and transparency support.

Q: How do I open an AVIF file?

AVIF files open in Chrome, Firefox, Safari (from macOS Ventura), Edge, and GIMP 2.10+. Support is growing rapidly, but some older image editors may not yet handle AVIF natively.

Q: AVIF vs WebP: which should I use?

AVIF provides better compression and quality than WebP, especially for photographs. However, WebP has broader software support today. Use AVIF for maximum performance on modern browsers and WebP as a reliable fallback.

Q: What is an XBM file?

XBM (X BitMap) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster &amp; vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose XBM when its particular strengths match the publishing target.

Q: How do I open an XBM file?

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open XBM natively. On mobile, iOS Photos and Google Photos display XBM in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our XBM to JPG or XBM to PNG converter.

Q: How do I convert an XBM file to another format?

Upload the XBM to KaijuConverter and pick a target format (JPG, PNG, WebP, HEIC, TIFF, BMP, SVG, PDF). The conversion runs in the browser via ImageMagick and returns a download in seconds. No account or installation required; both input and output delete automatically within two hours.

AVIF

AVIF Image

Raster & Vector Images

AVIF 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.

About AVIF files

XBM

X BitMap

Raster & Vector Images

XBM (X BitMap) is a monochrome image format used in the X Window System for cursor and icon bitmaps. The format stores pixel data as C source code arrays, making it directly includable in X11 programs.

About XBM files

Strengths Comparison

AVIF Strengths

Best-in-class compression efficiency — 30-50% smaller than JPEG for the same quality.
Royalty-free and patent-unencumbered (unlike HEIC).
Supports alpha transparency, HDR, wide gamut (BT.2020), and up to 12-bit color.
Progressive decoding: a blurry preview appears while the file is still downloading.
Supported in all major browsers since late 2022 — no polyfills needed.

XBM Strengths

Valid C source — embeddable.
Text-editable.
Tiny files.
X11-native since 1989.

Limitations

AVIF Limitations

Encoding is CPU-expensive — an AVIF export can take 10-30× longer than JPEG.
Older software (pre-2022) cannot open AVIF without plugins.
Email clients still largely ignore it — stick to JPEG for attachments.
Metadata support (EXIF, XMP) exists but tooling is less mature than for JPEG.

XBM Limitations

1-bit monochrome only.
Legacy — modern UIs use PNG/SVG.
No compression.
