Compress Image to 100KB

Shrink a photo to 100KB or less in a few seconds. Many online forms reject images above a set size, and 100KB is a limit you meet often: job portals, university admissions and visa forms often cap photos at 100kb. The compressor runs entirely in your browser, tries different quality levels and, if needed, smaller dimensions, and stops at the best-looking result that fits under 100KB.

Features

Private by design

Your photo never leaves your device. Compression happens in the browser, so it is safe for ID photos and documents.

Smart quality search

The tool searches for the highest JPEG quality that fits under 100KB instead of using one fixed setting, so faces and text stay sharp.

Works on phones

Pick a photo straight from your gallery or camera on Android or iPhone and download the result.

When to use it

Job applications

Many recruitment portals limit profile photos and scanned certificates to 100KB.

University forms

Admission forms ask for a photo and signature under 100KB; compress both before you start.

Email and chat

A 100KB image sends instantly even on slow mobile data, while still looking clear on screen.

Frequently asked questions

How do I compress an image to exactly 100KB?

Upload the image and the tool reduces it to 100KB or just under. Exactly 100KB is rarely possible, but anything below the limit is accepted by upload forms.

Will the image lose quality?

Some detail is lost when a large photo is squeezed to 100KB, but the tool keeps the highest quality that fits. Starting from a well-lit, in-focus photo gives the best result.

Are my photos uploaded anywhere?

No. The image is processed in your browser with JavaScript and is never sent to a server, so it stays private.

Which formats are supported?

JPG, JPEG, PNG and WebP. The result is saved as JPG, the format most forms accept.

How long does it take?

Usually one or two seconds on a phone or computer, because nothing is uploaded and the work happens on your own device.

Can I compress several images?

Yes, one after another. Each image is compressed separately in your browser, so you can do a photo, a signature and a scanned certificate in a row without waiting for uploads.

Does compressing remove location data?

Yes. Re-encoding the image drops most hidden metadata such as GPS location and camera details, which is a small bonus for privacy when you upload a photo to a public form.
