Automatically optimize image size and quality
Images never leave your browser — fully client-side
Upload and compress multiple images at once
Image Compressor processes JPG, PNG, WebP, AVIF, and similar files locally in the browser. It supports quality, maximum dimension, output format, batch processing, and ZIP download without uploading images to a server.
Smaller files usually require more quality loss, while lossless PNG and already optimized images may not shrink further. GIF input is converted to WebP with only the first frame, so animation is not preserved.
No. Reading, resizing, and encoding all happen in the current browser.
The source may already be optimized, or the selected format and quality may not produce a smaller result. The original is kept when same-format output is larger.
GIF files can be read, but the current result is a WebP containing only the first frame, so animation is not preserved.
