masstree.inPDF Tools
Merge, split, compress, rotate, number, reorder, watermark, sign and convert PDFs without sending them anywhere. Your files stay on your device.
Runs in your browser — nothing is uploaded or stored on a server.
How to split
Pages to remove
Rotation
Numbering
Compression
Pages are redrawn as images, so text stops being selectable. Keep the original if you need to search it later. With a target size, quality and resolution are lowered step by step until the file fits.
Output
Page size
Watermark
Your signature
Placement
This is a visual signature placed on the page, the same as signing a printout — not a cryptographic certificate.
Output
Only the text is kept, in paragraphs with a page break between pages. Scanned PDFs have no text — turn them into images and let the assistant read them.
Working…
What each tool does
- Split — save every page as its own PDF, one file per range, or pull out only the pages you list.
- Remove pages — delete blank or unwanted pages before you upload or print.
- Rotate — turn sideways scans the right way up, all pages or just some.
- Page numbers — add “1”, “Page 1” or “Page 1 of 12” in the corner or centre you choose.
- Reorder pages — drag page thumbnails into a new order, and remove or rotate any of them on the way.
- Watermark — stamp text across every page, diagonally, tiled or as a footer line. On ID copies, a line such as “Only for KYC with …” stops a copy being reused elsewhere.
- Sign — draw or type a signature and place it on the first, last or every page, with today's date if you want it.
Shortcuts for common jobs
The most popular tabs also have their own pages with the settings already chosen. You can compress a PDF to any quality or size in KB, or go straight to compress a PDF to 200 KB or 100 KB for online forms. There are also pages to merge PDFs into one file, turn JPG photos into a PDF, convert PDF pages to JPG and convert a PDF to Word.
About the signature
The Sign tool places a picture of your signature on the page — the same as signing a printout and scanning it. It is not a Digital Signature Certificate (DSC), so it won't do for filings that require one, such as company filings on the MCA portal.
Questions
Are my PDFs uploaded to a server?
No. The tools use the pdf-lib and pdf.js libraries inside your browser. The file is read from your device and the result is written back to it; there is no upload at all.
How does compression work?
Each page is redrawn as a JPEG at the quality and resolution you pick and rebuilt into a new PDF. It shrinks scanned documents and photo-heavy PDFs a lot, but text becomes an image, so it can no longer be selected or searched. Use a lower quality for e-mail, higher for printing.
Can I choose page ranges?
Yes. Type ranges like 1-3, 5, 8-10. Split can make one file per page, one file per range, or a single file with only the pages you list.
Does it work with password-protected PDFs?
Files with an open password cannot be read. Files that only restrict printing or editing usually work.
