How to sign a PDF online
Upload your PDF or image using the tool above. Click "Create Signature" to draw with your mouse or finger, type your name in a handwriting font, or upload a signature image. Pick a color — black, blue, red, or green. Click anywhere on the document to place the signature. Add multiple signatures to different pages. Hit "Download Signed PDF" when done.
Is this secure?
Yes. eDocu processes everything in your browser. Your file is never uploaded to any server. PDF rendering uses pdf.js and the signed PDF is generated using pdf-lib — both open-source, client-side libraries. When you close the tab, your document is gone from memory.
eDocu vs. certified e-signature services
Use eDocu for: internal approvals, personal documents, simple contracts between known parties, signed forms, or any situation where a drawn/typed signature is sufficient.
Use a certified service for: legally binding contracts that may be disputed, government submissions, or compliance-regulated industries.
