Self-attest a document in seconds.

Drop a scanned marksheet, certificate, or ID copy and stamp it with “Self-Attested”, today’s date, your name, and — if you like — your signature. Pick a corner, set a size limit if the portal needs one, and download. Everything runs in your browser; nothing is uploaded.

What “self-attested” means

For most government job and exam applications you submit self-attested copies — photocopies or scans you verify yourself by writing “Self-Attested”, signing, and dating them, instead of getting them stamped by a gazetted officer. Originals are only needed later, at document verification.

Keep it under the upload limit

Many portals cap each uploaded document at 100–500 KB. Set a target size and the tool compresses the stamped image to fit, the same way our certificate compressor does — so it uploads on the first try.

Your privacy

Your documents and signature never leave your device. Nothing is uploaded, stored, or logged — the stamping happens entirely in your browser with the HTML Canvas API.

Frequently asked questions

What does self-attesting a document mean?
Writing "Self-Attested" with your signature (and usually the date) on a photocopy or scan to certify it yourself — many Indian government applications accept this in place of gazetted attestation. This tool places that text and your signature image onto the scan.
Can I use my real signature?
Yes — add a photo or scan of your signature and position it with the stamp. The Signature Extractor tool can first clean it to black-on-white.
Does it reduce the quality of my document?
No — the stamp is drawn onto the image at its original resolution. You can optionally set a KB target if the portal has a file-size limit.
Is my document uploaded?
No. Everything happens in your browser — the document never leaves your device.
