How to compress an image to 500 KB

  1. Choose your images. Photos, scans, signatures — one or many, JPG, PNG or WebP.
  2. Pick the size. 500 KB is already chosen; pick another size any time.
  3. Press “Compress”. Download each image, or all of them as a ZIP.

Good to know

  • Private — images are compressed by your own browser. Nothing is uploaded, so it works for photos of ID cards and certificates too.
  • The sharpest image that fits — quality is lowered only as far as needed, and the image is made smaller in size only if quality alone isn't enough.
  • Already small enough? An image already under the target is kept exactly as it is.
  • Exact pixel size needed? Set “longest side at most”, e.g. 600 px, and the image is resized before compressing.

Frequently asked questions

How do I compress an image to under 500 KB?

Choose your images; 500 KB is already selected. Press "Compress" and download. Each image comes out as the sharpest version that fits under 500 KB, made smaller in size only if quality alone isn't enough.

Are my images uploaded?

No. Compression happens entirely in your browser, on your own device. Your images are never sent to our server.

Which formats can I compress?

JPG, PNG and WebP images, and anything else your browser can open. The result is a JPG, which every upload form accepts, or WebP if you prefer a smaller file.

Will the image lose quality?

As little as possible: the tool keeps the highest quality that fits under 500 KB, and only reduces the width and height when it has to. Photos taken on a phone are turned the right way up.

Can I compress several images at once?

Yes. Add as many as you like; each is compressed to the same target, and you can download them one by one or all together as a ZIP.
