PDF Toolkit

Merge, split, extract, reorder, rotate, duplicate, sign, watermark, number, crop, raster-compress and convert PDF pages.

Issue marks, signature and document settings

Marks and crop apply to selected pages, or every page when none are selected. Raster compression reduces scan-heavy files but removes searchable text and links.

Overlay and compare two drawings

Use one loaded page as the base, then add a second PDF. Normal mode overlays revisions; Difference mode makes changed pixels stand out.

Pages

Export preflight

  • Add pages to run checks.

Password removal, encryption and OCR are not faked here: they require specialist engines not currently bundled. Encrypted PDFs must be unlocked before opening.

About this tool

PDF Toolkit is a local-first PDF editor for construction documents: merge, split, extract, reorder, rotate, duplicate, sign, watermark, number, crop and raster-compress pages, plus overlay two drawings to compare revisions. It's built for estimators issuing and checking drawings without uploading them anywhere.

How to use it

  1. Drop in one or more PDFs or images.
  2. Select pages and rotate, delete, duplicate or reorder as needed.
  3. Add issue marks, a stamp preset or a signature line under Document settings.
  4. Export the finished PDF, or use Overlay and compare for two revisions.

FAQ

Is the PDF Toolkit free?

Yes — editing, organising and previewing pages is free and unlimited.

What does Pro add?

Exporting the finished PDF and the drawing comparison is free, with a small vishvaddi.com footer on each page; Pro exports without it.

Are my files uploaded?

No — files are read and processed entirely in your browser and never uploaded.

Can it remove passwords or run OCR?

No — those need specialist engines not bundled here; encrypted PDFs must be unlocked before opening, and password removal/OCR aren't faked.
