Details
Image compression reduces the file size of photos and illustrations, which can reduce transfer, attachment and storage size. Measure the effect on the complete page and the network conditions your users experience.
Processing runs in your browser and the selected image is not uploaded to a Tools Hub server. On shared devices, also review local downloads and browser security.
The quality slider ranges from 0.1 to 1.0. Start around 0.7, then compare text, edges and gradients at the intended display size. Max width resizes and compresses in one step.
FAQ
Can I compress images without losing quality?
It depends on the image and display size. Use 0.7-0.8 as a starting range, then compare fine text, edges and gradients with the original.
How many images can I compress at once?
There is no hard limit. However, since processing uses your browser memory, we recommend processing in batches of a few files at a time.
Are my files uploaded to a server?
No. Everything happens in your browser. Your files never leave your device.
Will my original image be deleted?
No. The compressed image is created as a new file that you download using the download button.
