Compress images online

Make JPG, PNG and WebP files smaller without a visible drop in quality. Drag the slider to compare the original and the result side by side.

Open the board Free. No sign-up. Your files stay on your device.

How to do it

  1. Drop one or many images onto the board.
  2. Select an image and open the Compress tab.
  3. Choose a quality, or switch to Target size and enter a limit such as 200 KB.
  4. Compare with the slider on the image, then download.

Quality or target size?

Use quality when you want to control how the picture looks. Use target size when a form or website says "under 200 KB": the tool searches for the best quality that fits under your limit. PNG can be made smaller with fewer colours or with lossless OxiPNG, and you can also convert to JPG or WebP for much smaller files.

When to use it

Use it when a website, form or email rejects a photo as too large, or when you want a page of pictures to load faster. A phone photo is often several megabytes, while a form usually wants a few hundred kilobytes.

Tips for better results

  • Use target size when a rule says "under 200 KB". Use quality when you want to judge how the picture looks.
  • Check the before and after slider on faces and small text. That is where compression shows first.
  • If the target cannot be reached, reduce the width and height first, then compress again.
  • Keep the original photo. A compressed copy cannot get its lost detail back.

Questions

How do I compress a photo to 200 KB?

Open the Compress tab, choose Target size, type 200, and download the result.

Does compressing hurt quality?

A little, by design, but at moderate settings the difference is hard to see. The before and after slider lets you check.

Are my photos uploaded?
