Frequently asked questions
Practical answers about formats, privacy, and what happens in your browser.
How much can an image be compressed?
Savings depend on the source image, output format, dimensions, and quality. The live estimate shows the actual encoded result from your browser.
Which output format is smallest?
WebP is often a good balance of size, quality, and compatibility. Results vary, so compare it with JPG for your image.
Does compression reduce dimensions?
Only if you select a maximum dimension. Choose “Keep original size” to preserve the pixel dimensions.
Are images sent to a server?
No. Your browser performs the compression locally and your file never leaves the device.
