Description
Oversized web images slow page loads, and compressing bluntly risks wrecking quality. RIOT's approach lets you compress while watching — original on the left, compressed on the right in real time, dragging the quality slider while the size and result update, until you are satisfied.
Free, on Windows, macOS and Linux, going since 2008.
Live comparison preview: original and compressed sit side by side, size and quality updating as you drag the quality slider, for precise balance between quality and size.
Multi-format optimization: it optimizes JPEG, PNG and GIF separately, stripping redundant data and compressing palettes to drop size noticeably.
Batch processing: multi-core batch compression of a whole set saves time slimming an entire site's images.
Metadata cleanup: optionally strip EXIF and other metadata to shrink size further and remove privacy information.
Light and proven: small and focused on one job, in development for over a decade, a reliable old tool for slimming web images.
