PDF Tools

Five document tools built on pdf-lib and Mozilla's pdf.js — contracts and records stay on your machine.

PDFs are the highest-stakes files people push through converters: contracts, statements, IDs. Every tool here — merge, split, images→PDF, PDF→JPG, watermark — runs in your browser on pdf-lib (MIT) and pdf.js (Mozilla's own renderer), so there is no server copy to leak, retain or subpoena.

jpg → pdf

Combine JPG, PNG, WebP or HEIC images into a single PDF in your browser — one page per photo, original quality, nothing uploaded.

merge pdf

Combine multiple PDFs into one document directly in your browser — contracts and records never touch a server.

pdf → jpg

Render each PDF page to a high-resolution JPG in your browser — single page downloads directly, multi-page arrives as a ZIP.

split pdf

Split a PDF into one file per page, downloaded as a ZIP — processed entirely in your browser with no upload and no page-count paywall.

watermark pdf

Stamp a diagonal text watermark (CONFIDENTIAL, DRAFT, …) across every PDF page in your browser — documents never leave your device.

Pick the right tool

You have	You need	Tool
Several PDFs	One document	Merge PDF
One PDF	Individual pages	Split PDF
Photos / scans	One submission-ready PDF	JPG → PDF
A PDF	Images for slides/chat/web	PDF → JPG
A draft or confidential doc	A visible stamp on every page	Watermark

Two honest boundaries: password-protected PDFs are rejected (decrypt in the native app first — password cracking is deliberately not offered), and Office conversions (PDF↔Word/Excel) are absent because doing them well needs server-class rendering; a bad browser version would mangle your documents, so we'd rather not ship one.
