PDF Editor

Not while you edit or download. Editing runs in your browser using PDF.js (for rendering) and pdf-lib (for editing), so your PDF stays on your device. The only exception is when you click Share Link: the finished PDF is then uploaded, stored privately, and deleted automatically when the link expires (1, 7, or 30 days). You can also delete the link yourself right after creating it.

Yes, with Edit Text: click a line and retype it. Behind the scenes the old line is covered with its own background color and the new text is written on top in the closest standard font (Helvetica, Times, or Courier), matching the original size and color. This works for PDFs made from Word, Google Docs, and similar apps; scanned PDFs are images, so there is no text to edit. As with Redact, the original text is hidden rather than erased from the file's data, so don't rely on either tool to remove confidential information.

Click Signature / Image, then draw it with your mouse, finger, or stylus, type your name, or upload a JPG/PNG. Drawn and typed signatures are saved as transparent PNGs, so no white box appears around them. The signature lands on the page you're viewing, where you can drag and resize it. For uploads, a PNG with a transparent background works best.

Yes. All pages of your PDF are rendered and you can add annotations to any page. To remove a page, click Delete page above it; the page is dimmed and you can restore it until you download or share. When you download, all annotations are applied and the deleted pages are left out of the final PDF.

PDF.js renders the preview at a scaled size for your screen. The download converts your click position back to PDF coordinates. Small positioning differences can occur due to font rendering differences between browsers and PDF viewers. For precise placement, use a slightly larger font size and verify in the downloaded file.
