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.
