Compress Image to 100 KB — Free Online
Free online image compressor pre-set to 100 KB. Shrink photos to fit upload limits in seconds — nothing to install, nothing to sign up for.
What this page does
100 KB is the workhorse size for online forms in Pakistan: passport-style photos, application uploads, and document scans. Many portals cap uploads at exactly 100 KB, which is why this preset exists — pick your photo, compress, download, upload, done.
The mini compressor below is pre-set to a 100 KB target. Drop in your photo and it re-encodes it until it fits under the limit, then lets you download the result. No account, no watermark, no queue.
Common Pakistani portal photo requirements
| Use case | Common size limit |
|---|---|
| FPSC online application photo | ~25 KB |
| CSS online application photo | ~30 KB |
| Passport-style photo uploads | ~100 KB |
| General job-portal & university uploads | 50–200 KB |
Common requirements — always check your form's rules; limits change and some portals also fix dimensions and dimensions only.
Getting the best result
- Start with the biggest original you have. Compressing from a large, sharp source always beats compressing an already-small file.
- Crop first. Trimming away background you do not need shrinks the file before compression even starts — the full tool lets you crop visually.
- Match the portal, not the maximum. A 25 KB target for an FPSC photo is a requirement, not a suggestion; uploading a bigger file just gets rejected.

My portal says 'photo must be under 100 KB'. Will this pass?
The tool targets a file that fits under 100 KB, and shows you the exact final size before you download. Just make sure the photo also meets the portal's dimension rules (e.g. 600×600 px) — file size and dimensions are separate requirements.
Does the file leave my device?
No. The compressor is a static web page — there is no server to upload to. Your photo is read and re-encoded by your own browser, and the download is generated locally on your device.
What if my photo is already under the target size?
Then you are done — upload it as is. Compressing an already-small photo again would only lose quality for no benefit. The tool shows the final size so you can confirm before downloading.
