Frequently asked questions
Is JPG Compressor free to use?
Yes. JPG Compressor is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does JPG Compressor upload your image to a server?
No. JPG Compressor processes your image inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in JPG Compressor.
Do I need to install anything to use JPG Compressor?
No installation is needed. JPG Compressor runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use JPG Compressor on a phone or tablet?
Yes. The JPG Compressor interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your image when I close the tab?
It is discarded. JPG Compressor keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
