Compress an image to 100 KB

Application forms and portals often say a photo must be under 100 KB. Set that as the target and get the sharpest picture that still fits. It runs on your device, so the photo is not uploaded.

Open the board Free. No sign-up. Your files stay on your device.

How to do it

  1. Drop your photo onto the board and select it.
  2. Open the Compress tab and switch to Target size (KB).
  3. Type 100 as the target.
  4. Compare with the slider, check the size in the result, then download.

What if it cannot reach 100 KB?

The tool tries lower and lower quality until the picture fits under your limit. A large photo with lots of detail may not get there by quality alone, and the tool will tell you. In that case make the picture smaller in pixels first with the resize tab, then compress again. Photos shrink best as JPG.

When to use it

Use it when an application form, a job portal, an exam registration or a government site says the photo must be under 100 KB. The tool searches for the best quality that still fits under your limit, so you do not have to guess.

Tips for better results

  • Check whether the rule asks for the file to be at most 100 KB, or exactly a range. Stay safely below the maximum.
  • Many forms also fix the width and height. Resize the picture to the required size first, then compress.
  • If the tool says it could not reach the target, make the picture smaller in pixels and try again.
  • Use JPG for photos. It is the most widely accepted format for forms.

Questions

How do I make a photo under 100 KB?

Open the Compress tab, choose Target size, type 100 and download the result. If it cannot reach the target, resize the picture smaller first.

Will the photo still look good?

At 100 KB a normal photo keeps enough detail for a form or profile picture. Use the before and after slider to check faces and text.

Is my photo uploaded?

No. It is processed on your device and never sent to a server.
