About PDF Tools
PDF is the format you receive contracts, reports, resumes, receipts, and invoices in. Yet the moment you try to merge, split, or edit one, the wall hits: "do I need to pay for Adobe Acrobat?" Yes, Acrobat is ~$20 a month.
JiniTools provides the everyday PDF workflows — merge, split, convert to images, edit pages — for free with no sign-up. More importantly, your PDF never leaves the browser. Contracts, tax invoices, ID copies, the kind of document you most hesitate to upload — process them safely here.
Internally we use audited open-source libraries (pdf-lib, PDF.js); everything runs in browser memory. The same tools work on mobile, so you can merge or split PDFs on the go.

FAQ
Are password-protected PDFs supported?
No. Decrypt the file in your PDF viewer first. We do not accept passwords because it is bad security practice.
Will Korean/Japanese/Chinese text render correctly?
Yes. The PDF → Image and PDF → Text tools auto-load CJK font data via PDF.js. Very old PDFs with broken font embedding may still display oddly.
Is there a file-size limit?
No server-side cap — only your device memory. Roughly: 500 MB on a desktop, 200 MB on mobile, stable.
Can I reorder pages in a merged PDF?
Yes. PDF Merge and PDF Page Editor both support drag-and-drop reordering, including on touch devices.
How can I verify the PDF is not uploaded?
Open DevTools (F12) → Network tab, then drop your PDF. You will see zero upload requests.
