Compress Image to 100KB

Get any photo under 100 KB while keeping it sharp - enough room for a clear, detailed image.

Small Enough for Forms, Big Enough to Look Right

100 KB is the point where compression stops being a compromise for most images. A 600 × 600 photo at 100 KB is essentially indistinguishable from the original on screen, and even a 1080 × 1080 social post holds up well. That makes it the sweet spot for document scans that need to stay readable, and for web images where page weight matters but quality still does. Because the compressor searches for the highest quality that fits rather than applying a fixed setting, you get the most detail 100 KB can buy for your particular image.

How to Compress an Image

1

Upload your image

Pick a JPG, PNG, WebP, or GIF file from your device. It stays on your computer - nothing is sent to a server.

2

Set a target size or quality

Type the exact KB size a form or upload limit requires, tap one of the presets, or switch to the quality slider for manual control.

3

Download the compressed file

Check the before and after sizes, then save the smaller image in JPG, PNG, or WebP.

Good Reasons to Target 100 KB

  • Scanned documents and certificates that must stay readable
  • Application forms that allow up to 100 KB per attachment
  • Blog and article images where page speed matters
  • Product photos for marketplace listings with size caps
  • Email attachments you do not want to clog an inbox
  • Images for a CMS that rejects anything larger

Compressing to 100 KB

Will I see any quality loss at 100 KB?

For most images at normal web dimensions, no. The preview shows you the actual result before you download, so you can judge it on your own photo rather than trusting a number.

Is 100 KB good for a scanned document?

Yes, it is usually the right target - text stays crisp and the file is small enough to attach anywhere. Below about 50 KB, small print starts to break up.

Can I keep PNG and still hit 100 KB?

Sometimes, but PNG is lossless so quality settings do not apply to it. If a PNG will not fit, switching the output to JPG or WebP almost always will.

How much smaller is 100 KB than a phone photo?

Typically 30 to 50 times smaller. A modern phone photo runs 3-5 MB, so the saving shown on screen is usually well above 95%.
