How to compress an image to 500 KB

Quick answer: To compress an image to 500 KB, add your images, check the target, press Compress and download.

  1. Add your images. Drag photos onto the box above or click it to choose them. JPG, PNG, WebP and AVIF all work, and you can add many at once.
  2. Check the target. It's already set to 500 KB. You can type a different number or pick another common size.
  3. Press Compress. Each image is saved at the highest quality that still fits under the limit. The new size is shown next to it.
  4. Download. Save each image, or download them all as one zip.

When do you need a 500 KB image?

Many sites refuse files over a set size. 500 KB limits are common for website uploads, marketplaces, real-estate listings and email attachments. 500 KB keeps a photo sharp enough to fill a laptop screen. It's a good default for websites.

How it works

The tool tries different JPG quality levels and keeps the best one under your limit. If even low quality is too big, it makes the photo a bit smaller and tries again, so you always get the sharpest photo that fits.

Is it safe for ID photos and documents?

Yes. Nothing is uploaded: the image is processed on your own phone or computer, and hidden data such as GPS location is removed from the result.

Can I compress a PNG to 500 KB?

Yes. Choose JPG as the format (the default) for the smallest file. If the form needs PNG, choose PNG: it can only get smaller by reducing the pixel size.
