About this task

Half a megabyte suits email attachments, marketplace listings and forms that allow a photo or scan of reasonable quality. It is where compression becomes almost invisible for typical photos.

A photo from a recent phone is usually a few megabytes, so reaching 500 KB means an effective reduction by several times. The tool lowers JPG quality in small steps and keeps the highest setting that fits, which for most pictures looks very close to the original at normal viewing size.

If you are sending several photos in one message, add them all at once: each is compressed to the same target and they download together as a ZIP. If the recipient needs one document instead, turn them into a PDF afterwards with JPG to PDF.

Compression is lossy: zoom in and you may see soft detail in hair and textures. If a print shop or designer needs the full-quality file, send the original instead.

How to do it

  1. Add your photo or photos. JPG, PNG, WebP and other common formats open, and you can add several at once.
  2. The target is already set to 500 KB and the output is JPG. Change either if your site needs something else.
  3. Press Compress. Quality is lowered first, and the picture is made smaller only if quality alone is not enough.
  4. Check the size shown for each image, then download. Several images come as one ZIP.

Compress image is a DocPro Pro tool on the web. You can open it, choose your file and set every option without an account; the final step asks you to sign in to DocPro Pro (A$5.99/month after a 7-day free trial, cancel anytime). Free tools never ask.

Frequently asked questions

Is 500 KB enough for a good photo?

For viewing on screens, yes. For large prints, no: send the original.

Why not just lower the pixel size myself?

You can, with Edit image. The compressor does both for you and stops as soon as the file fits.

Will it change the picture format?

It outputs JPG by default. PNG can only be resized, not compressed to a size target.
