Reduce image size (KB)

Bring a photo down to the number of kilobytes you need, or set the quality yourself – no software to install.

How it works

  1. Add an image: drag it in, choose it from your device or paste it with Ctrl+V.
  2. Adjust the options – the preview changes as you move the sliders.
  3. Download the result, or click "Apply and continue" and move on to the next tool.

When a form asks for "a photo under 100 KB", type that number and the tool finds the best quality that still fits. If looks matter more than size, switch to quality mode and watch the result live. WebP gives a smaller file than JPG at the same visual quality.

Questions and answers

Where do my images end up?

Nowhere. The image is opened and processed in your browser, on your phone or computer, and is not sent to our server.

How much does it cost?

Nothing. The tools are free, with no sign-up, no daily limit and no watermark on the result.

Can I use several tools on the same image?

Yes. Click "Apply and continue", then pick the next tool from the bar – the image stays loaded. Undo brings back the previous state.

Which images can I open?

JPG, PNG, WebP, GIF and BMP, plus AVIF in recent browsers. Save iPhone HEIC photos as JPG first.
