Offline PDF Merge, Split & File Converter

Merge, split, compress, sign and number PDFs; PDF to JPG or text; images to PDF; DXF, CSV. Offline: files are never uploaded.

Most free PDF tools upload your file to someone's server. This one does not. Every file is processed inside your browser, so drawings, contracts, datasheets and quotes stay on your computer. It even works with the network switched off. PDF TOOLS • Merge PDF: combine up to 20 files in the order you choose • Split PDF: one file per page range, or one per page, saved together as a ZIP • Organize pages: reorder, remove or duplicate pages with a sequence such as 3,1,5-7 • Rotate PDF: all pages or a selected range • Watermark PDF: CONFIDENTIAL, DRAFT or any text, with angle and opacity FILE CONVERTERS • Images to PDF: site photos and scans into one PDF, A4 or US Letter, with margins • Image resizer: shrink photos for email and convert to WebP, JPEG or PNG • DXF to SVG: preview a 2D CAD drawing and save it as SVG, no CAD software needed • CSV comma ↔ semicolon: fix CSV files that open in a single Excel column • CSV ↔ JSON: convert tables both ways Limits: up to 30 MB and 500 pages per job. Password-protected PDFs are not supported. Editing a signed PDF removes its signature, as with any tool. PRIVACY No uploads, no account, no analytics, no ads. The extension asks for no permissions at all. Made by PlantAxiom for engineers who handle drawings and documents every day. Free engineering calculators at plantaxiom.com.
