Lightweight PDF editing in the browser

Not every task needs Adobe Acrobat. RatPDF’s editor lets you add text, images, and annotations for quick fixes — mark up a contract, stamp “DRAFT”, or insert a missing signature block.

What browser editing is good for

Last-minute label corrections
Adding notes before client review
Inserting a logo on a generated PDF

Limitations

Complex prepress, CMYK colour proofing, and heavy form redesign still belong in desktop tools. For watermarks and passwords, use dedicated watermark and protect tools.
