What the tool does to get your file under 100KB.
Exact size, every time
Pick 100KB and get a file at or under that limit. There is no quality slider to set.
Handles large phone photos
Photos straight off a phone camera (usually 2-5MB) are compressed on our server, so your device does the least work.
Resolution kept where possible
Quality is lowered first. Pixel dimensions are reduced slightly only when the size target cannot be met otherwise.
Deleted within 1 hour
Files are auto-deleted from our servers within 1 hour of processing.
Nothing to install
It runs in your browser.
Phone, tablet or computer
Use it from any modern browser.

What to know about the 100KB headroom
Why this cap is used when clarity matters more than minimal size.
Why 100KB is used when detail needs to stay legible
100KB gives significantly more room than 20KB or 50KB, which matters for scanned documents with fine text or certificates where small print needs to stay readable after compression — not just a face photo where a lower cap is usually enough.
How exact-target compression preserves more at a higher cap
The same highest-quality-that-fits approach applies here, but with a 100KB budget the tool can retain noticeably more visual detail than it could at 20KB or 50KB before it needs to compress further.
Best suited for scans and documents, not just photos
Certificate scans, ID document images, and marksheets often need enough resolution for small text to stay sharp — a 20KB or 50KB target can blur fine print, while 100KB usually keeps it legible.
Quality vs. dimension trade-off at this size
At 100KB, most standard photos and document scans reach the target through quality adjustment alone, without needing to shrink pixel dimensions — dimension reduction typically only kicks in for unusually large or high-resolution source files.
Where a 100KB limit typically shows up
Passport and visa application photo uploads, government ID document scans, and certificate/marksheet uploads for verification commonly specify 100KB or a similar range — check your specific form, since document scans often get a higher allowance than plain photos.
When even 100KB isn't the right fit
If a form has no strict KB cap and you just want a smaller file without hitting an exact number, our general compress-image tool with a percentage-based reduction may give you a better quality-to-size balance than forcing an exact byte target.
Frequently asked questions
Why do forms ask for a 100KB photo?
A 100KB cap keeps application servers fast and storage costs down when thousands of applicants upload photos at once — which is why it's such a common limit on Indian government recruitment portals. SSC CGL, UPSC, IBPS bank exams, and several state PSC and railway recruitment forms all specify a photo size limit in this range, and uploads over the limit are simply rejected at submission.
The problem is that a photo straight off a phone camera is usually 2-5MB — 20-50x too large. Resizing dimensions alone doesn't reliably hit an exact KB target, which is what this tool does directly: pick 100KB, upload your photo, and download a file sized right for the form.
How it works
Your photo is re-encoded to land at or under 100KB while keeping text and faces readable in a form-style image, usually with no visible quality loss. If you need a different size, the same tool supports custom targets like 20KB or 50KB too.
