This free Add Watermark tool is built for people in the United Kingdom who need a fast, private way to get work done without installing software or creating an account. You open the page, choose your file, and finish on the same device you already trust with your documents.
Everything happens on your device in your browser. Your files are never uploaded to our servers, never stored by us, and never shared with anyone. You do not need to register. When you close the tab, temporary working copies from the session are gone. Your originals stay where you saved them unless you download a new file.
UK users come here for practical reasons. Teams marking drafts, freelancers branding sample packs, landlords labelling property packs, and anyone who needs a clear “not final” stamp before sharing. The tool is designed around those everyday moments — not around technical jargon, not around forced trials, and not around watermarks that make a document look unprofessional.
Because the work stays on your device, you can handle routine paperwork with more confidence than you would when sending the same file to an unknown upload site. That matters for tenancy packs, invoices, coursework, HR forms, and client proposals.
Tenants and landlords: shrink, mark, or tidy packs before portals and email. Freelancers and small businesses: prepare proposals and invoices that clear size limits. Students and tutors: convert, mark up, or split reading packs. Admin and compliance teams: keep only the pages someone asked for, without sending an entire binder to a third-party cloud.
Everything happens on your device in your browser. Your files are never uploaded to our servers, never stored by us, and never shared with anyone. You do not need to register. When you close the tab, temporary working copies from the session are gone. Your originals stay where you saved them unless you download a new file.
If your workplace, university, or client has rules about uploading documents to third-party clouds, keeping the work on your device is often the simplest way to stay on the right side of those rules while still getting the format or layout you need.
Preview or open the download before you hit send. It is easier to fix a mistake now than to explain a wrong attachment later.
Place a single mark in the centre or a corner, or tile it across the page from a light 2x2 grid up to a denser 5x5 pattern. Use From/To or tick page previews when only some sheets should be stamped — for example watermarking sample pages but leaving the final invoice clean.
The tools work in modern browsers on Windows, Mac, Chromebooks, iPhones, iPads, and Android devices. Everyday letters, invoices, and forms usually run smoothly on a phone. Very large files, long scan packs, or graphics-heavy documents are often more comfortable on a laptop where you have more memory and a bigger screen to review the result.
If a conversion feels slow, close other heavy tabs, plug in power on a laptop, and try again. Private on-device tools use your device’s resources — that is the trade-off for not uploading.
After you download, give files clear names: client-invoice-march.pdf, tenancy-pack-compressed.pdf, proposal-draft-watermarked.pdf. Future you — and anyone helping with an audit, move, or dispute — will thank you.
Keep the original file as a master copy whenever you can. Treat the new download as a working version for sharing, submitting, or archiving in a specific folder structure.
If you handle other people’s documents, double-check you are sending the right version before you hit send. A thirty-second preview prevents awkward corrections later.
Combine PDF merges several files into one. Compress PDF shrinks oversized attachments. Split PDF extracts or removes pages. Organize PDF reorders and rotates pages. PDF to Word and Word to PDF move between editable and fixed formats. Edit PDF adds notes, blackout, and highlights. Sign PDF places a visual signature. Protect PDF locks a file with a password. Unlock PDF removes a password you already know. Rotate PDF fixes sideways sheets. Page Numbers PDF adds clear numbering. Watermark PDF stamps text or a logo. Crop PDF trims margins and scanner edges. PDF Forms fills fillable fields. PDF to Excel pulls text rows into a spreadsheet. PDF to JPG and JPG to PDF move between images and PDF pages. Extract Images from PDF turns pages into PNG or JPG files.
Pick the tool that matches the job. Using the right step once is faster than forcing the wrong format through three workarounds.
Results depend on the quality of what you start with. A blurry phone photo will not suddenly become perfect print quality. A scanned contract with crooked pages may still look crooked until you organize or rescan. The tools respect your content; they do not invent missing detail.
Encrypted or damaged PDFs may fail to open. If that happens, try an unlocked copy from the sender, or export a fresh PDF from the original app.
These tools are free utilities for everyday productivity. They are not a substitute for professional legal, medical, or certified digital-signature services when a formal certificate is required.
