Installation

Windows 10 version 2004 or later, or Windows 11, x64. The portable ZIP includes the .NET runtime; no separate .NET installation or WebView2 is required. Windows 11 was tested; Windows 10 has not been independently tested.

Extract the entire ZIP and keep adjacent packaged files together. Run PDFToolbox.exe. The executable is not Authenticode signed, so Windows may show a reputation/security warning. Download only through official ALMARFELD/GitHub links or this verified mirror. Do not disable Windows security.

Features

• Merge, split, extract and rotate PDF pages
• Reorder, duplicate or remove pages in a reviewable plan with undo
• Convert JPG/PNG/BMP to PDF and PDF pages to PNG/JPEG
• Add watermarks and page numbers; edit document metadata in a copy
• Protect with PDF AES-128 or unlock using valid credentials
• Lossless stream compression; no saved output if it is not smaller

Limitations and safety

No OCR, general batch processing or direct PDF text editing. Originals are not overwritten. Known signed PDFs are refused for rewriting. Page-editing tools refuse interactive forms and can discard bookmarks or other document-level structures. Editing encrypted PDFs requires an unlocked copy; unlocking needs valid credentials, not password cracking. Compression may not reduce already optimized or scanned files. Metadata editing is not secure sanitization. Limits include 256 MiB and 5,000 pages per PDF, 100 PDF inputs and 512 MiB combined per operation; advanced PDF preservation is not universally guaranteed.

Verify the download

This mirror uses the unchanged official GitHub release ZIP: PDFToolbox-v1.0.0-win-x64.zip.

Get-FileHash -Algorithm SHA256 .\PDFToolbox-v1.0.0-win-x64.zip

Expected SHA-256: f67ff6c9604635eac96948fd6d716fa6abb4a91478ad965ea8a18c655bd464bf

Compare with the accompanying PDFToolbox-v1.0.0-win-x64.zip.sha256. A matching hash confirms the published bytes; it is not a malware scan or an Authenticode signature.
