Applications
Application-materials PDF organizer
Turn scattered PDFs and phone scans into one ordered PDF. See every page as a thumbnail, drag to reorder, delete, rotate, or export just the pages you tick. Files stay in this browser tab — nothing is uploaded.

Organized files can be checked again for missing items and naming before you submit.
How it works
Fully local. pdf-lib assembles the output and pdf.js paints the page thumbnails — both libraries run in your browser tab. Files live only in memory: no uploads, no server copy; close the tab and everything is gone.
Per-page operations. Every imported page is a card you can drag, move with the ↑↓ buttons (works without a mouse), rotate in 90° steps, delete, or tick for a selected-pages export. The output PDF keeps the grid order you see.
Limits and unsupported files. Single file up to 30 MB and 200 pages total, chosen so phones do not run out of memory. Encrypted or damaged PDFs are skipped with a named error; the rest of your files still import. OCR, Word→PDF, compression and signing are intentionally out of scope.
Images to PDF. JPG/PNG scans become one page each — either fitted onto an A4 sheet (landscape images get a landscape sheet) or kept at original size. Phone photos taken sideways are straightened using the EXIF flag before embedding.
Questions people ask
Are my files uploaded to a server?
No. Merging, reordering and thumbnail rendering all happen in your own browser tab's memory — files never leave the page. Closing the tab erases everything; it also works offline.
Can it handle encrypted or password-protected PDFs?
No — encrypted or damaged PDFs are skipped with an error naming the file, while your other files still import. Remove the password in your own PDF reader first.
What page size do phone scans get in the PDF?
Two options: Fit to A4 scales the image onto a centred A4 sheet (landscape images get a landscape sheet); Original keeps the pixel size at 96dpi. Sideways phone photos are straightened via the EXIF flag before embedding.
Are there size or page limits?
Yes: 30 MB per file and 200 pages in total. Anything over the limit is skipped with a clear message — the caps exist so phone browsers do not run out of memory.
What should I do after organizing?
Send the exported PDF back through the Document checklist: confirm nothing is missing, names are clean and file sizes fit the school's rules before you submit.
