What the tool does to get your file under 50KB.
Exact size, every time
Pick 50KB 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 50KB middle ground
Why this is the default limit most portals pick.
Why 50KB is the most common general-purpose limit
50KB gives enough headroom for both a clear ID-style photo and a signature scan to look sharp, while still being small enough to keep upload servers fast. That balance is why it's the default many recruitment and application portals settle on.
How exact-target compression differs from a quality slider
A generic compressor set to a fixed quality percentage gives you an unpredictable file size depending on the photo. This tool works backwards from the size — 50KB — and finds the highest quality that still lands at or under that number.
Both photos and signatures usually fit comfortably
Unlike a tight 20KB cap, 50KB is generous enough that most passport-style photos and signature scans reach the target without visible quality loss — you're less likely to see compression artifacts at this size.
Quality reduction vs. dimension reduction
The tool reduces encoding quality first, since that has the least visible impact. Only if a photo still can't fit 50KB at reasonable quality does it also shrink the pixel dimensions slightly — this rarely happens at 50KB unless the source photo is unusually large or detailed.
Where a 50KB limit typically shows up
Recruitment application photo uploads, resume/profile picture fields, and several university admission portals commonly specify 50KB as their photo size cap — check your specific form, since some use it for signatures instead of photos.
What makes a photo harder to compress at the same KB target
A busy, colorful background pushes file size up faster than a plain one at the same quality level — a grayscale scan or a photo with a simple background will generally look sharper at 50KB than a colorful photo with lots of fine detail.
Frequently asked questions
Why do forms ask for a 50KB photo?
A 50KB 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 or signature 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 — 40-100x too large. Resizing dimensions alone doesn't reliably hit an exact KB target, which is what this tool does directly: pick 50KB, 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 50KB while keeping it readable for a small ID-style image, usually with no visible quality loss. If you need a different size, the same tool supports custom targets like 20KB or 100KB too.
