Visual signature only
This tool overlays an image or text so agreements look signed on screen. It does not embed PKI digital signature fields trusted by Acrobat for legal non-repudiation.
E-Signature Tool
Draw or upload a signature image (or type your name) and stamp it on every page of a PDF with pdf-lib — runs locally; this is a visual mark, not a cryptographic digital signature.

Category: File Conversion & Handling
Not a cryptographic signature. This overlays an image or typed line for appearance only — not PKI digital signature fields. Everything runs in your browser.

Signature image
Transparent PNG works best.
Choosing a corner resets the box; drag again to fine-tune.
Frequently Asked Questions
Are password-protected PDFs supported?

PDF to JPG / PNG
New
Export PDF pages as JPEG or PNG images in your browser (Mozilla pdf.js + canvas). Pick render scale, optional page list, and JPEG quality. Multi-page exports download as a ZIP. Max ~35 MB file size and up to 1000 pages (browser memory is the practical limit — use page ranges for huge jobs) — nothing is uploaded.

PDF to DOCX
New
Upload a PDF (up to 50 MB) and convert to a downloadable .docx via Dynamic Duniya’s file API — best for text-heavy PDFs; multi-column layouts and images may not transfer cleanly. Progress while uploading; open the result in Word or Google Docs and review formatting.

DOCX to PDF
New
Upload Word .docx or legacy .doc (up to 50 MB) and download a PDF via the server file API. Output fidelity depends on LibreOffice on the server — review complex layouts. Progress while uploading; suggested download name converted.pdf.

Merge / Split PDF
New
Merge: first-page previews in a horizontal strip — drag cards to set merge order. Split: optional “Load page previews” then drag thumbnails (four per row, scrollable) to reorder pages before splitting by ranges or every N pages; ranges use preview slot numbers when previews are loaded. Zip when multiple parts. Client-side pdf.js + pdf-lib — max ~35 MB per file, 150 pages, 12 PDFs for merge.

PDF Watermarking
New
Stamp text (font size, opacity, rotation, corner/center placement) or a JPEG/PNG image across every page using pdf-lib locally. Encrypted PDFs are not supported. Download a watermarked copy — your file never leaves the browser.
