Drop your PDF here
PDF files only, processed entirely in your browser
Three steps. Done in your browser.
Drop your PDF
Drag a PDF onto the editor or click to browse. Rendered locally using PDF.js, nothing is transmitted over the network.
Add text and annotations
Select the text tool, click anywhere on the page, and type. Choose font, size, color, bold, and italic from the toolbar.
Save your edited PDF
Click Save PDF. Annotations are embedded into the document using pdf-lib. The file saves directly to your device.
When you need to edit a PDF.
From filling forms to annotating contracts, the browser Canvas API handles tasks that used to require a desktop application.
Filling in PDF forms
When a form is not interactive, the text tool lets you click each field and type your answer, then save a completed copy without printing.
Adding comments to documents
Review a report or draft by placing text notes directly on the PDF. Share the annotated file with colleagues for clear, contextual feedback.
Signing documents without printing
Type your name in a matching font over the signature line. Save and send, no printer, scanner, or Adobe subscription required.
Labelling scanned documents
Add a date, reference number, or category label to a scanned invoice or receipt before filing or sending to accounting.
Annotating contracts
Mark up a contract with clarifying notes on clauses to discuss. All annotations embed cleanly into the output PDF.
No Adobe Acrobat needed
Basic PDF editing tasks like adding text, notes, and signatures used to require Acrobat Pro. This tool does the same job, free, in any modern browser.
How it works under the hood.
When you open a PDF, PDF.js(Mozilla's open-source library) renders each page as a canvas element directly in your browser tab. Your annotations are managed as an overlay layer in memory using the browser's Canvas API.
When you save, pdf-lib loads the original PDF bytes, embeds your text annotations as native PDF text objects, and writes a new file. The result is a standard PDF that opens correctly in any viewer.
No server is involved at any stage. Your document never leaves your device.
