What size should a signature be for exam forms?

Most government exam portals require a scanned signature between 140×60 px to 200×80 px and under 20KB–50KB. Always check the specific exam notification for the exact requirement.

Should I use JPG or PNG for my signature?

For most exam and government portals, JPG is the required format. Use PNG only if the portal specifically asks for it or if you need a transparent background.

How do I scan my signature?

Sign on white paper with a black or dark blue pen. Use your phone camera in good light, or use a scanner app. Crop close to the signature, removing as much white space around it as possible before uploading.

My signature file is too large even after compression. What should I do?

Try reducing the target size further (e.g. Under 20KB) and ensure you select JPG as the output format. If the signature still exceeds the limit, also reduce the dimensions using the preset sizes.

Practical guidance for Signature Resize

Resize your scanned signature to standard sizes (140×60, 160×60, 200×80 px) and compress under 20KB for online forms. Student tools are useful for exam forms, identity updates, scholarship portals, and job applications that reject files outside strict limits. JaldiDocs is designed for everyday Indian document workflows where a small mismatch in size, format, page order, or file weight can cause an upload to fail.

Before you use the tool

Keep the original file unchanged so you can restart if a form has a different requirement.
Check whether the portal asks for pixels, millimetres, page size, file format, or maximum KB/MB.
Use a clear file name without special symbols before uploading to government, exam, tax, or business portals.

After downloading

Read the latest official notification before final submission.
Match both dimensions and file size, because many portals validate both.
Keep the original file unchanged so you can make a new version if a portal rejects the first one.
Open the final file once on your device and confirm it is readable before submitting it anywhere.

Privacy and accuracy note

The tool runs in your browser wherever possible, which means your file is processed on your own device instead of being uploaded to JaldiDocs. Official requirements can still change, so always compare the output with the latest instructions from the website or organization where you plan to submit it.
