Image Compression (Compress Tab)

The Compress tab with format selector (AVIF, WebP, JPEG) and preset pills (High Quality, Balanced, Min Size, Original). The Compress tab with format selector (AVIF, WebP, JPEG) and preset pills (High Quality, Balanced, Min Size, Original).
The Compress tab re-encodes images with WASM codecs running entirely in your browser.
  • Output formats: AVIF, WebP, and JPEG encoders are bundled. AVIF typically produces the smallest files; JPEG offers the widest compatibility.
  • Presets:
    • High Quality: minimal visible loss, larger files.
    • Balanced: the default for web and sharing.
    • Min Size: aggressive compression for thumbnails and previews.
    • Original: passes the source through without re-encoding.
  • Keep Originals: on by default. Compressed outputs are written alongside the source file (e.g. IMG_0421.avif next to IMG_0421.jpg). Turn off to replace the original in place.
  • Metadata preservation: compression runs after your metadata edits, so IPTC/XMP tags written in other tabs are preserved in the output.

EXIF orientation

Re-encoded images are written in their decoded pixel orientation. If your source uses an EXIF orientation flag (common on phone JPEGs), the compressed output bakes the rotation into the pixels, usually what you want, but different from the original.
