PDF & document tools
A cleaner document-workflow centre for common engineering submissions, dossiers and controlled document preparation.
Account sign-in is separate from the current browser-based PDF processing. Private cloud storage, document folders and account-linked saving are not yet available. Registration requires WordPress membership registration to be enabled by the site administrator.
Start with your files
Choose the document operation, then add files to the workspace. Files remain on your device unless a tool explicitly states otherwise.
Merge PDF
Prepare multiple PDF files in the required sequence before combining them.
Workspace preparation
Split & Extract PDF
Plan page ranges for extracting sections from larger submissions.
Workspace preparation
Reorder & Rotate
Organize the intended page sequence and rotation requirements.
Workspace preparation
Images to PDF
Collect site photographs or scans into an ordered document set.
Workspace preparation
Page Numbers
Define numbering conventions for reports and technical dossiers.
Workspace preparation
Watermark & Stamp
Plan controlled labels such as Draft, For Review or Approved.

Document control and safe PDF handling
Before processing: retain the original PDF files unchanged, verify page order and page counts, and make a working copy. For client-approved engineering records, compare the exported result against the originals page by page before issuing it.
Preserving signatures, stamps and annotations
Some PDF transformations can invalidate digital signatures, alter form fields, flatten annotations or remove interactive content. A visible handwritten signature is not the same as a cryptographic digital signature. Never assume that a merged, split, rotated or watermarked PDF retains its original signature validity. For controlled dossiers, preserve approved originals and verify all comments, tick marks, stamps and attachments after export.
Recommended workflow by operation
Merge: record the required file sequence, confirm page counts and check duplicate or missing pages. Split/extract: use explicit inclusive page ranges and verify the resulting first and last pages. Reorder/rotate: compare against an approved document index. Images to PDF: use readable resolution, consistent orientation and descriptive filenames. Page numbers: avoid covering existing document references or signatures. Watermark: distinguish internal review labels from actual client approval.
Privacy and limits
The current page is a preparation workspace, not a certified document management system. Do not upload confidential or controlled documents to any future online processing service without reviewing its privacy and retention terms. PDF processing and downloadable exports should be used only after their implementation has been independently tested.
PDF processing — Merge and Extract
Select PDF files above. Merge combines them in the displayed selection order; Extract saves selected pages from the first PDF. Processing runs in your browser using PDF-Lib, loaded from a public library CDN. Do not use these operations on digitally signed PDFs if the original signature must remain valid.
Select PDF files to begin. Encrypted files and digital signatures may not be supported.
The document workspace organizes files and workflows in-browser. PDF rewriting/export is intentionally not represented as complete until the required PDF processing engine is bundled and tested.
