SignFlow – eSignature Suite

About

SignFlow – The PDF Signing Suite That Lives in Your Browser
Stop paying monthly fees just to sign a document. SignFlow gives you a full professional eSignature suite as a Chrome extension — no accounts, no cloud uploads, no subscriptions. Your documents stay on your device.

✍️ SIGN PDFS VISUALLY
Open any PDF and place your signature exactly where you need it. Click to drop, drag to reposition, and grab the corner handle to resize. What you see is what gets burned into the PDF — no coordinate guessing, no alignment surprises.

📋 FILL FORM FIELDS BEFORE SIGNING
SignFlow automatically detects form fields in your PDF. Text boxes, checkboxes, dropdowns — all rendered as live editable fields right on top of the document. Fill everything out, then sign. Download a single completed PDF.

✏️ ADD FREE TEXT ANYWHERE
Need to add a date, note, or annotation on a PDF that has no form fields? Switch to Text mode and click anywhere on the page. A draggable text box appears. Adjust font size, pick ink color, move it anywhere.

6 WAYS TO CREATE YOUR SIGNATURE
Draw — Sign with your mouse or trackpad using a freehand canvas with pen thickness and color controls
Type — Choose from 4 signature-style fonts. Your name previews live in each font as you type
Upload — Use your existing signature image (PNG with transparent background works best)
Stamp — APPROVED, REVIEWED, CONFIDENTIAL, DRAFT, VOID, or custom initials
Date — Insert today's date in US, EU, ISO, or long format
Digital Certificate — Create a professional certificate stamp with your name, organization, email, and timestamp
