Online Signature Resizer
Most application forms want the signature as a small JPG with an exact size and a KB limit. Pick your exam in the table below for its exact rule, or set any size yourself with Custom Size.
Everything happens in your browser: take a photo of your signature, crop it, and download a file that fits.

Signature Resizer
- Sign on plain white paper with a black or blue pen, and take the photo from straight above.
- To lower the KB without changing the pixel size, use the Signature Compressor in the Tools tab.
- If the form gives the size in cm, enter it in cm. PhotoSuvidha converts it to pixels for you.
Common mistakes
- Signing on lined, coloured or crumpled paper.
- Lots of empty paper around the signature. Crop close so it stays readable.
- A faint pen, or a photo taken at an angle.
- A file below the minimum KB. Some forms reject very small files.
Frequently asked questions
How do I reduce my signature to under 20 KB?
Open the Signature Compressor in the Tools tab, choose 20 KB and download. To change the pixel size too, use Custom Size.
Is there one standard signature size for exams?
No. Each exam sets its own size and KB limit. The table on this page lists the values for popular exams.
Is my photo uploaded or stored anywhere?
No. PhotoSuvidha resizes and compresses the image inside your browser, on your own phone or computer. The image is never sent to our server.
Is it free?
Yes. There is no sign-up, no watermark and no charge.
