Photo resizer in KB for exam forms
This photo resizer in KB turns any photo, signature or scan into a JPG of the exact size your form asks for. Pick a target, add a minimum if there is one, and download.
We'll make your photo 50 KB.
JPG, PNG, WebP or HEIC, up to 25 MB
Processed on your device. Never uploaded.
More optionsNow: 50 KB. Tap to pick another size.
Leave empty unless your form gives a minimum, like 20 KB for IBPS photos.
The picture may get smaller in pixels (at most 2000 px on the long side) so it stays sharp at low KB.
Your file will be 45–50 KB.
About this tool and size
Photo in KB size vs pixels
Pixels are the width and height of the picture, such as 200×230. Kilobytes are how much space the file takes. The same 200×230 photo can be 15 KB or 80 KB depending on the JPEG quality. This tool searches for the highest quality that keeps the file under your target, so you lose as little detail as possible.
We count 1 KB as 1024 bytes, the way most portals do, and keep the file under the 1000-byte reading of your limit too.
An image converter in KB and JPG at once
Phones save photos as 2–5 MB HEIC or JPG files. This KB converter opens HEIC, PNG and WebP on your device and saves a JPG, the format every exam portal accepts, so changing the format and reducing photo KB happen in one step. For a whole set of files, Batch compress handles up to 20 images at once.
Common limits on exam forms
Banking forms (IBPS, SBI, RBI) want photos of 20–50 KB and signatures of 10–20 KB. NTA forms such as NEET UG, JEE Main and CUET UG take photos from 10 to 200 KB, and RRB signatures must be 30–49 KB. Your exam page lists every document with its pixel size too.
Small files: signatures and thumbs (5–30 KB)
Photos and declarations (35–100 KB)
Large photos and documents (150–500 KB)
How to use it
- Add your image. Take a photo or choose one from your gallery. JPG, PNG, WebP and HEIC work, and the file stays on your device.
- Choose the size. Tap a preset from 10 to 500 KB or type your own. Add a minimum KB if your form has one.
- Pick keep or shrink. Keep dimensions changes only the quality. Allowing downscale lets the picture get smaller so it stays sharp at low KB.
- Download. When the pass check shows all ticks, download the JPG.
Questions
How exact is the size?
The file always lands between 90% and 100% of your target, never over it. For a 50 KB target that means 45–50 KB.
What does "Keep dimensions" do?
It keeps the width and height in pixels exactly as they are and only lowers the JPEG quality. Turn it off to let the picture shrink when a low KB target would otherwise make it blocky.
Why would I set a minimum KB?
Some forms reject files that are too small, for example IBPS photos must be at least 20 KB. With a minimum set, the file never goes below it.
Can this KB resizer make a file bigger?
Yes. If your photo is under the minimum, the tool raises the JPEG quality, and adds invisible padding if needed, so it reaches the range. The picture is never stretched.
Is this safe for my documents?
Yes. Nothing is uploaded. All processing runs in your browser, and the page works offline after the first visit.
