Questions About Image Compressor
How does the online image compressor work?
The compressor decodes your image directly into your browser's memory using HTML5 Canvas, re-encodes it at your target quality setting, and compares the resulting byte footprint. Zero data travels across the network.
Will compressing my image reduce visible quality?
At recommended quality settings (75% - 85%), human eyes generally cannot detect any visual differences, yet file size is often reduced by 60% to 80%.
Are my uploaded photos safe and private?
Yes. Processing is 100% client-side inside your browser sandbox. Your images are never saved to our servers or sent to any external third-party APIs.
Which image formats can I compress?
Toolora supports JPG/JPEG, PNG, WebP, GIF, and AVIF formats.
