Compress and resize images, free

How it works: in your browser, not on a server

Most online image compressors upload your picture to a server, process it there and send the result back. This tool does not work that way: your browser decodes the image, resizes it and re-encodes it at a new quality. The file never leaves your machine.

That has two practical consequences. One is that you can safely drop in images you would not hand to an unknown service — a photographed contract, a medical scan, an unreleased product. The other is that there is no daily limit and no queue: the only thing setting the pace is your own device.

The EXIF data disappears — on purpose

A photo taken on a phone usually carries GPS coordinates, an exact timestamp and the device identifier along with it. Re-encoding preserves none of that, so the downloaded image no longer says where it was taken, or on what.

One EXIF field is read and applied to the picture before compression: the orientation. Without it, photos taken with the phone turned sideways would arrive lying on their side — that is the one piece of metadata that belongs in the pixels rather than in the file header.

What people use it for

Email attachments. Most mailboxes cut the message off at 20–25 MB. Type a number into the "target file size" box and the image comes out at exactly that.

Websites and shops. 200 KB loads where a 4 MB product photo used to — the same picture in a fraction of the time, and Core Web Vitals notices.

Upload limits. Government portals, grant applications and job boards routinely impose a fixed size cap. Resize and compress in one step, with nothing to install.
