PDF Organizer – Merge, Split, Rotate & Reorder Pages
One place to fix a PDF before you upload it: combine marksheets and certificates into a single file, put pages in the right order, turn sideways scans upright, remove blank pages, or split one big scan into separate documents.
How to use the PDF Organizer
- Choose one or more PDF files. Every page appears as a numbered thumbnail; pages from several files are added one after another.
- Drag a thumbnail to a new position (or use ◀ ▶ on a phone). Press ⟳ to rotate a page by 90° and ✕ to delete it.
- To merge, press Download PDF – you get one file with all pages in the order shown.
- To split, tick pages and press Extract selected pages, press Split every page for a ZIP of single-page PDFs, or type ranges such as
1-3, 4-6.
Online application portals often ask for a single PDF with all documents, for example 10th and 12th marksheets together, under a fixed size. Organise the pages here first, then use the PDF Compressor if the merged file is too large. Text and quality of the original pages are kept exactly, because pages are copied, not re-printed.
🔒 Privacy: this tool runs entirely in your browser using JavaScript. Your files are never uploaded to Crop Desk or any other server, and you can even use it offline once the page has loaded.
Frequently asked questions
Is there a limit on the number of files or pages?
There is no fixed limit. Very large PDFs (hundreds of pages) depend on your device memory; on a phone, work with smaller batches.
Will merging reduce the quality?
No. Pages are copied as they are, so text stays sharp and searchable. Only rotation information is changed when you rotate.
Can I open password-protected PDFs?
PDFs that need a password to open cannot be read. Remove the password in the app you used to create it, then add it here.
Are my documents uploaded?
No. The PDF is opened and rebuilt inside your browser with the open-source pdf.js and pdf-lib libraries. Nothing is sent to a server.
