How to annotate a PDF
Add notes and visual markup without changing the original PDF. Everything happens in your browser, and no account is required.
-
Open your PDF
Choose Open PDF, select a PDF from your device, or drag it into the workspace. Use the page thumbnails to move through a multi-page document.
-
Choose an annotation tool
Use the toolbar to add text, a signature, an image, a barcode, a QR code, freehand ink, a highlight, or a shape.
-
Place the annotation
Click the page to place text or imported content. For drawings and shapes, drag across the page. Double-click a tool to keep it active while adding several annotations.
-
Adjust the appearance
Select an added object to move, resize, rotate, duplicate, or delete it. Use the properties panel to change text, font, color, fill, size, alignment, and opacity.
-
Review every page
Check the page thumbnails for your changes, complete any supported PDF form fields, and use Undo or Redo to correct mistakes.

Download the annotated PDF

Questions about Ship Toolkit PDF tools
These answers apply to all browser-based PDF tools on Ship Toolkit.
Are my PDF files uploaded to a server?
No. Ship Toolkit processes PDFs locally with JavaScript in your browser. Your files are not uploaded to Ship Toolkit.
Will a PDF tool change my original file?
No. The tool creates a new file for you to download. The original PDF on your device is not overwritten.
Which PDF files may not work?
Password-protected, encrypted, damaged, or unusually complex PDFs may not open or process correctly. Very large files may exceed your device's available memory.
Which browsers are supported?
Use a current version of Chrome, Edge, Firefox, or Safari. JavaScript must be enabled, and older browsers may not support every feature.
Can I use the PDF tools on a phone or tablet?
Yes, but detailed editing is easier on a larger screen. Performance and maximum file size depend on the memory available on your device.
Why does a large PDF take longer to process?
Processing happens on your device. PDFs with many pages, high-resolution images, or complex content require more memory and processing time.
