WEBP

WebP Image

Raster & Vector Images

WebP is a modern image format developed by Google that provides superior lossless and lossy compression. Files are typically 25-35% smaller than equivalent JPEG or PNG images at the same visual quality.

About WEBP 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

WEBP Strengths

  • Smaller file sizes than JPEG, PNG, and GIF at equivalent visual quality.
  • Single format for lossy photos, lossless graphics, transparency, and animation.
  • Full alpha channel support with smaller files than PNG.
  • Now universally supported in all modern browsers.
  • Open-source reference implementation (libwebp) by Google.

XBM Strengths

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

Limitations

WEBP Limitations

  • Some older software and image editors still don't read WebP natively.
  • Max dimensions are 16,383 × 16,383 — lower than JPEG or PNG.
  • Print workflows rarely support WebP (no CMYK, limited color management).
  • Editing tools are less mature than JPEG/PNG; round-tripping can lose quality.

XBM Limitations

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