Stamp a watermark across a whole folder of PDFs at once — each processed in your browser and packaged into one ZIP. Nothing is uploaded.
or drop files / a folder here
Drag a folder (or several PDFs) onto the upload box, or click to pick files. Type your watermark text — for example CONFIDENTIAL — then click "Apply to all". Each PDF is stamped one by one, and when it finishes you click "Download ZIP" to get every watermarked file in a single archive. If you dropped a folder, any non-PDF files inside it are filtered out automatically, so you don't have to clean the folder first.
No. Every PDF is processed entirely in your browser, on your own device — nothing is uploaded to any server, and there's no account or sign-in. Your documents never leave your computer, which is exactly why it's safe for confidential files.
You get one ZIP file (dockdocs-batch.zip) containing all the watermarked PDFs. Each output keeps its original name with a "-watermarked.pdf" suffix — so report.pdf becomes report-watermarked.pdf. Your original files are left untouched.
This batch tool processes up to 30 PDFs per run. If you add more, only the first 30 are kept. There's no fixed file-size cap — since everything runs in your browser, the real limit is your device's memory, so very large files or weak machines will simply be slower. For a bigger job, split it into batches of 30.
Yes, it's completely free with no signup, no trial, and no usage limits beyond the 30-files-per-run batch size. The only watermark on your PDFs is the text you type — DockDocs never stamps its own logo or branding onto your files.
Not in the batch tool. It uses a fixed default placement — a diagonal watermark across each page — to keep the whole folder consistent. If you need a custom position, opacity, or font size, use the single-file Watermark tool instead, which gives you full control over one document at a time.
