Privacy. This tool works entirely inside your browser. Your file is never sent to us, never saved, and never seen by anyone else. Read how we handle files

Add up to twenty images and they are compressed one after another, entirely inside your browser. Nothing is uploaded, and each result can be downloaded on its own or the whole set taken as a single ZIP.

The same quality setting is applied to every image, so this works best on a batch of similar things — a set of photographs, or a set of scans — rather than a mixture of photos and screenshots, which want very different settings.

Because the work happens on your own device, a large batch of big images will make the page think for a while and will warm up a phone. If you have a lot to get through, a computer will do it faster.

How to use it

  1. Choose your files, or drag them onto the box above.
  2. Set the size you need, then press the compress button.
  3. Download the result. Nothing is kept once you leave the page.

Files it accepts

  • JPG
  • PNG
  • WebP
  • Up to 25 MB per file
  • Up to 20 files at once

Questions

How many files can I add?

Twenty at a time by default. For more, run it in batches — the tool is free and there is no limit on how often you use it.

Can I give each image its own setting?

Not in bulk. One quality setting is applied to all of them. For individual control, use the single-image compressor.

Where does the ZIP come from?

It is assembled in your browser from the results, then handed to you as a download. It is never created on, or sent to, our server.

Is this tool free?

Yes. Every tool here is free, and you do not need an account, an email address or a phone number.

Is my file uploaded to your server?

No. This tool runs inside your own browser, so the file never leaves your phone or computer. Once the page has loaded you can even switch off your internet connection and the tool will still work.

Which files can I use?

This tool accepts JPG, PNG and WebP. The largest file it will take is 25 MB.
