Compress Image to 500 KB for free, privately

Upload forms often reject images above a fixed size, and 500 KB is a common limit for websites, listings and portals with a 500 KB limit. This page is set up for it: the tool searches for the highest quality that still fits under 500 KB, and only makes the picture smaller in pixels if quality alone is not enough.

Half a megabyte is generous for a photo: most pictures reach it at high quality without any change in pixel size. Everything runs in your browser with the mozjpeg and libwebp encoders, so your images are never uploaded.

How it works

  1. Add images: drop JPG, PNG or WebP files, click to choose them, or paste a screenshot.
  2. Pick Quality or Target size, and a format if you want to convert.
  3. Press Compress images. Each file shows its new size and how much it saved.
  4. Download images one by one, or all of them as a ZIP.

Frequently asked questions

How do I compress a photo to 500 KB?

Add the photo and press Compress images. The target size is already 500 KB; change the number if your form asks for another limit. Each image shows its new size, and "Resized to fit" if the pixel size had to be reduced too.

Will the image look worse at 500 KB?

The tool keeps the highest quality that fits. Small photos and screenshots usually look unchanged; a large, detailed photo squeezed into 500 KB is also scaled down, which looks fine on screen but is not meant for printing.

How do I resize an image to 500 KB?

Resizing to 500 KB means making the file 500 KB or smaller, which is what this page does: add the image and press Compress images. If the form also gives a size in pixels or centimetres, set that first with the Image Resizer or Resize Image in cm, then bring the file under 500 KB here.

Can I compress several images at once?

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

Are my images uploaded?

No. Compression runs in this page on your own device. Nothing is sent to a server.
