Compress Image

Compress JPG, PNG and WebP images to make them smaller for websites, email and forms that have an upload limit. Move the quality slider and see the new file size live before you download. Compress many photos at once, privately, on your own device.

Your files never leave your device. Everything runs in your browser: no uploads, no sign-up, no watermarks, works offline.

How to use Compress Image

1. Drop one or more images into the box.
2. Move the quality slider and watch the live size preview.
3. Optionally convert to WebP or JPG for bigger savings.
4. Press “Compress” and download your images (or a zip).

How it works

What quality should I pick?

Around 70–80% usually looks the same as the original at a fraction of the size. Watch the live preview to find the right balance.

Why does my PNG barely shrink?

PNG is a lossless format, so a quality setting has little effect. Choose WebP or JPG as the output format for big savings.

Are my files uploaded anywhere?

No. neverupload has no server that receives files. Everything happens inside your browser on your own device, and the files never leave it. You can even disconnect from the internet and the tool keeps working.

Does it work offline?

Yes. After your first visit the app is cached by your browser, so you can use it without a connection. You can also install it as an app from your browser menu.
