Quick Summary: PDF Editor

Our online PDF editor lets you annotate, highlight, and edit your PDF documents directly in your browser with no installation required. Siliph's PDF Editor is a free in-browser PDF utility featuring a built-in AI assistant to optimize formatting, suggest settings, and answer compliance questions.

What does PDF Editor do?

PDF Editor lets you change text, add images, highlight, draw shapes, white out sensitive lines, insert links, and fill forms directly in the browser.

When to use PDF Editor

  • Fixing typos without re-exporting from Word
  • Adding notes, highlights, or images to a contract
  • Filling forms and annotating review comments
  • Quick edits when you do not have Acrobat installed

Desktop editors are overkill for quick fixes. Our toolbar covers the tasks people actually need: typo fixes, annotations, stamps, and light layout tweaks.

Upload once, edit visually on the page canvas, then download the updated PDF. Changes are applied as standard PDF layers readable in Acrobat, Preview, and Chrome.

Free plan users can complete basic edits without creating an account. Paid plans raise file size and hourly task limits.

Siliph edit utilities—crop, rotate, headers, Bates numbers, metadata—apply changes in the browser with encrypted handling from the moment you drop a file. Finished PDFs auto-delete within two hours on the free plan, and every edit workflow opens without signup.
