Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

This one fixes a bunch of smaller issues, improves responsiveness when making a bunch of small settings changes, and adds input support for SVGs. ADDED - SVG import support (SVGs are rasterized on import with safe size limits). - Retry button when compression is canceled before the first preview completes. IMPROVED - More reliable canceling of in-progress processing, including JPEG/WebP encodes and PNG optimization. - AVIF encoding reliability for very tall images. - Transparency handling: background fill (white/black/custom + custom color) is now remembered. FIXED - Checkerboard transparency background rendering on macOS 26; clamped square size to avoid edge cases. - Re-importing/replacing the same image no longer removes the active file unexpectedly. - Restored: the "Remove Alpha" toggle is available again when the output format supports alpha.
