Resize a photo or signature to an exact KB and pixel size
Online exam and government job forms — SSC, UPSC, IBPS, NEET, state PSCs and more — demand your photo and signature in a precise size, such as a signature under 20 KB or a photo under 50 KB at set pixel dimensions. This free tool resizes and compresses your image to hit those exact limits, right in your browser, so your upload is accepted the first time.
Who uses this tool
Applicants filling exam forms for UPSC, SSC, IBPS, NEET, and state PSCs where photo and signature must be under a strict KB limit, as well as passport and visa applicants and professionals resizing signatures for e-sign portals.
How to resize your image
- Choose your photo or signature.
- Pick a preset (e.g. "Signature — 140×60 px, under 20 KB") or type the exact pixel size and KB limit your form needs.
- Click Resize & preview, then download — the file lands under your KB limit automatically.
Frequently asked questions
How do I resize a signature to under 20 KB?
Choose the "Signature — 140×60 px, under 20 KB" preset (or set your own size and limit) and click resize — the tool lowers the quality just enough to fit under 20 KB while keeping the signature legible.
How do I resize a photo to 50 KB (or any KB) for an exam form?
Set the width, height and the maximum KB your form specifies, then resize. ToolGalli compresses the photo to land under that exact limit.
What photo and signature size do exam forms need?
It varies by exam, but a common requirement is a photo around 200×230 px under 50 KB and a signature around 140×60 px under 20 KB. Always check your specific form and use the custom fields if needed.
Will resizing make my photo blurry?
Only if the KB limit is very small for the chosen size. The tool keeps quality as high as the limit allows. Use "Fit & pad" to avoid cropping faces.
Is my photo uploaded anywhere?
No. The image is processed entirely in your browser and is never sent to a server.
