Frequently asked questions
How much smaller will my image get?
It depends on the quality setting — 80% quality typically cuts JPEG file size by 50–70% with barely any visible difference.
Are my images uploaded anywhere?
No. Compression happens on your own device using the browser's canvas API; your photos never leave your browser.
Which formats are supported?
JPG, PNG and WebP inputs. Output is JPEG for maximum size reduction — note that transparency is flattened to white.
Will this work on my phone?
Yes. The compressor works in any modern mobile or desktop browser.
