Edit PDF

Edit PDF makes small additions to a PDF directly in the browser: adding new text on top of a page, or placing a solid rectangle to visually cover part of a page, without ever leaving the device.

The PDF stays on this device and your changes are applied locally in a dedicated browser worker.

Edit PDF adds new text or visually covers an area. It does not modify existing text, and visual covering is not secure redaction — underlying content may still remain in the PDF.

Limits: one PDF up to 25 MB, 200 pages, and 75 MB output. Added text is capped at 500 characters with a font size from 6 to 96 pt. Encrypted or password-protected PDFs are rejected.

How to use it

  1. Select one PDF from your device and wait for its page count.
  2. Choose Add text or Cover area, then pick the target page.
  3. Configure the text or the cover rectangle using percentage-based position and size.
  4. Apply the edit and download the resulting PDF once the dedicated browser worker finishes.

After the page count is detected, choose which page to edit, then either add text at a chosen position and size or cover an area with a solid color box, sized and placed by percentage of the page. A dedicated browser worker embeds a built-in Helvetica font for added text and draws the requested rectangle directly onto the existing page, leaving the rest of the document untouched. This is not a full PDF editor: existing text in the document cannot be selected or modified, and the cover option is a visual overlay only — it is not secure redaction, and the original content underneath may still be extractable from the file. Files are not uploaded to Tooliba, retained after the session, or included in analytics. The source PDF may be at most 25 MB and 200 pages, generated output is limited to 75 MB, added text is capped at 500 characters with a font size between 6 and 96 points, and password-protected or encrypted documents are rejected rather than decrypted.
