About this task

100 KB is a very common limit for photos and scanned documents on many government and university upload forms, and it is a good balance: small enough for a form, large enough to keep a face or a page of text recognisable.

For a typical phone photo the tool usually has to reduce the pixel size as well as the quality, because a multi-megabyte image holds far more detail than 100 KB can carry. The output is still plenty for screen use. If the photo is already small, say a screenshot or an image saved from the web, it may fit with only a light quality change.

Photos of documents behave differently from portraits: sharp edges of text show compression blocks sooner than skin tones do. If your page is mostly text, a scan at lower resolution looks better than a heavily compressed high-resolution one, and the tool takes that route automatically when quality alone is not enough.

The result is always a new, smaller file, never bigger than your original; if the original is already under 100 KB and in the chosen format it is kept as is. Fine detail is lost when quality drops, so keep the original.

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 100 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 the quality good enough for a visa or exam photo?

The tool only reduces quality as much as it must, but each application has its own rules for the photo itself. Check the official requirements for size, background and framing.

Why is my 100 KB result smaller than 100 KB?

The tool stays at or below the target and picks the best quality that fits, so the result can land a few KB under.

Can I use WebP?

The tool can output WebP, but most forms accept only JPG, so JPG is the default here.
