About Fill And Sign PDF
Fill and Sign PDF lets you complete fillable PDF forms and add your signature without Adobe Acrobat, DocuSign, or any installed software. The form filler detects all interactive fields — text boxes, checkboxes, radio buttons, dropdowns — and presents them in a clean interface. The signature tool lets you draw with a mouse or finger, type your name in a handwriting font, or upload an image of your signature. For documents you want to lock down after signing, our PDF password protection tool adds an extra layer of security.
DocuSign starts at $15/month. Adobe Sign requires an Acrobat subscription. HelloSign charges per envelope after the free tier. Our fill-and-sign is free, unlimited, and runs entirely in your browser via our form filler engine — the completed PDF is signed and saved locally using pdf-lib without any server processing for the core feature. For documents that only need a signature (no form fields), our dedicated PDF signing tool is a faster workflow. For legally binding e-signatures with audit trails, we offer a premium flow built on the same compliant infrastructure as commercial e-sign providers.

Why Choose PDF AI Tools
We've built PDF AI Tools to replace expensive desktop software like Adobe Acrobat for 95% of common document workflows — at zero cost to you. Unlike competitors who gate features behind paywalls, add watermarks, or limit file sizes, our tools are genuinely free and genuinely unlimited. Your privacy matters: files processed client-side in your browser never touch our servers, and even AI-powered features use encrypted, auto-deleting processing pipelines.
Frequently Asked Questions
Is a drawn signature legally binding?
A drawn or typed electronic signature has the same legal standing as a wet (pen) signature under the ESIGN Act (US) and eIDAS (EU) for most document types. For documents requiring notarization or witnessed signatures, consult your jurisdiction's requirements.
What if my PDF doesn't have interactive form fields?
Use the text overlay mode — click anywhere on the PDF page to place a text box and type into it. For signatures on flat (non-interactive) PDFs, the signature placement tool works the same way as on form PDFs.
Can I save my signature to reuse it?
Yes — after drawing or typing your signature, it's saved in your browser's localStorage. The next time you open a PDF that needs signing, your saved signature appears as a one-click option.
Is my filled form data sent to your servers?
No. Form filling and signing runs entirely in your browser using pdf-lib. The completed PDF is assembled locally. We never see the form fields or their values.
