Powerful PDF tools that keep files private
Merge, split, compress, convert, organize, and edit PDFs directly in your browser. No uploads. No cloud processing. Your documents stay on your device.
Start with the essentials
Merge PDF
Combine several PDFs into a single document in the order you choose.
Split PDF
Break one PDF into several files by page ranges or fixed chunk size.
Compress PDF
Shrink image-heavy PDFs by rasterizing pages at a target quality.
JPG to PDF
Turn one or many JPG images into a single PDF.
PDF to JPG
Render each PDF page to a JPG image, packaged as a ZIP.
Add Watermark
Stamp diagonal text across every page — CONFIDENTIAL, DRAFT, etc.
Add Page Numbers
Insert page numbers with position and format control.
Rotate Pages
Rotate every page or a selection by 90°, 180°, or 270°.
The whole point is what doesn't happen
Conventional online PDF tools upload your document to a server, process it there, and send it back. PDFDig removes that step entirely. There is no upload, so there's no server-side copy to leak, retain, or forget to delete.
No uploads
Files are read into the tab, never transmitted.
Local processing
Your CPU does the work, in your browser.
No document collection
We never see or store your file contents.
You stay in control
Clear all local data with one click, anytime.

BrowseThree steps, zero uploads

Choose local files
Drag and drop, or browse. The file is read into your browser tab — it doesn't go anywhere else.
Process in the browser
PDFDig transforms the document using your device's CPU. Heavier jobs run without blocking the page.
Download the result
The finished file is generated locally and handed back to you as a download. Close the tab and it's gone.

Built for real document work
Freelancers & consultants
Combine contracts, invoices, and deliverables into one clean PDF before sending — without routing client files through someone else's server.
Students & researchers
Split readings, extract the pages you actually need, and convert slides to images for notes, all offline.
Small teams & ops
Stamp page numbers, add watermarks, and strip metadata on documents that shouldn't leave the building.
Anyone with a scanner
Turn photos and scans into tidy PDFs, compress them for email, and try local OCR when you need the text back.
Are my files really not uploaded?+
Correct. Every tool reads your file into the browser tab and processes it on your device. No request carrying your document is sent to PDFDig or any third party.
Do I need an account?+
No. There's no sign-up and no login. Open a tool, add a file, and download the result.
Does it work offline?+
Once the page has loaded, most tools work without a connection because the processing happens locally. OCR downloads a language model on first use.
What does PDFDig store?+
Only small preferences and, if you opt in, a local history of tool runs (metadata only — never the file). You can clear all of it from the dashboard at any time.
Is there a file size limit?+
There's no server limit because there's no server. Practical limits depend on your device's memory, since everything runs in your browser.
Your files stay on your device. Always.
Open a tool and see for yourself — there's nothing to install and nothing to sign up for.
