Image Compressor
Shrink your photos and images — quality-based compression, right in your browser.
This changes image quality, not dimensions — for resizing, use the Resize Image tool. Compressing strips all metadata (EXIF, GPS, camera info), which most people want anyway. PNGs with real transparency stay PNG with limited savings; fully opaque PNGs are converted to JPEG for a much smaller file.
Your files never leave this device — everything happens in your browser.
