The Image Compressor shrinks the file size of a photo — from megabytes down to a few hundred kilobytes — while keeping it looking almost the same. It is built for the everyday problem of a photo being 'too big' for WhatsApp, email, a job application or a website upload limit.
How much quality will I lose?
At 75% quality most people cannot see any difference on a phone screen, while the file often shrinks by 60–80%. Only drop below 50% if a strict size limit forces you to.
My form says the photo must be under 200 KB. What should I do?
Drag the quality slider down slowly and watch the 'After' figure until it falls under 200 KB, then download. If it still will not fit, resize the photo smaller first and compress again.
Are my files uploaded to a server?
No. The Image Compressor runs entirely in your browser — your file is processed on your own device and is never sent to ToolNest or anywhere else. Close the tab and everything is cleared.
