Free Online PDF Editor (Edit, Sign, Draw, & Erase)

A powerful, full-featured PDF editor that runs entirely in your browser. Add text, insert images, freehand draw, sign documents, and whiteout sensitive information without uploading your files.

Why Use ToolMini's PDF Editor?

Editing PDFs used to require expensive software like Adobe Acrobat Pro. Most online alternatives force you to upload your improved private documents to a remote server, creating potential security risks.

ToolMini changes the game. Our Pro PDF Editor is built with advanced WebAssembly technology that brings desktop-class editing features directly to your web browser. Whether you need to fill out a form, sign a contract, redact confidential text, or annotate a study guide, you can do it all here—instantly and securely.

Full Suite of Editing Tools

Add & Edit Text

Insert new text anywhere on the page. Choose from standard fonts (Helvetica, Times, Courier), adjust size, color, bold, and italics to match the original document.

Freehand Drawing

Use the pen tool to circle important sections, draw diagrams, or sign documents with your mouse or touchscreen. Customize stroke width and color.

Whiteout & Eraser

Need to hide sensitive data? Use the Whiteout tool to cover existing text or images with a clean white block. Perfect for redacting personal info.

Insert Images

Upload your company logo, a scanned signature, or an ID photo and place it anywhere on the PDF. Resize and position it with precision.

The "Client-Side" Security Guarantee

When you open a PDF in this editor, the file is processed locally by your device's browser. It is NOT uploaded to our servers. This architecture ensures:

  • 100% Privacy: We physically cannot see your contracts, bank statements, or medical forms.
  • GDPR/HIPAA Safety: Since data never leaves your computer, you maintain full control over compliance.
  • Instant Speed: Large files open immediately without waiting for uploads or downloads.

Draw your signature or upload an image of it to sign agreements legally.

Permanently cover up social security numbers, prices, or private addresses.
