Got a PDF with an annoying watermark plastered across every page? Maybe it’s a “DRAFT” stamp on a finalized document, or a trial watermark from a PDF tool you used once. Whatever the case, you don’t need to pay for Adobe Acrobat to get rid of it.
I spent two weeks testing 14 different tools and methods for removing watermarks from PDFs. Some worked perfectly in seconds, others mangled the formatting so badly I wished I’d just retyped the whole thing. Here’s what actually works in 2026, ranked by how well each tool handles real-world watermark removal.
If you’re also looking for a solid free PDF editor for other tasks, check out our guide to the best free PDF editors – several of the tools there handle watermarks too.

Important: When You Can (and Can’t) Remove a Watermark
Before we get into the tools, a quick reality check. Watermarks in PDFs come in two flavors:
Removable watermarks – these are separate layers added on top of the PDF content. They’re typically text or image objects that a PDF editor can select and delete independently. Most “DRAFT,” “CONFIDENTIAL,” or trial-version watermarks fall into this category.
Baked-in watermarks – these are flattened into the page content itself. The watermark is part of the same layer as the text and images. You can’t select it separately. This happens when someone prints to PDF after adding a watermark, or when the PDF has been flattened. Removing these is much harder and sometimes impossible without damaging the document.
Also, don’t remove watermarks from copyrighted material you don’t have rights to. That’s both illegal and honestly just not cool. This guide is for removing watermarks from your own documents.
Method 1: Google Docs (Fastest for Text Watermarks)
This is the method I reach for first. It works surprisingly well for text-based watermarks, and you already have the tool if you have a Google account.
Step-by-step process
- Upload your PDF to Google Drive
- Right-click the file and select “Open with > Google Docs”
- Google converts the PDF to an editable document. The watermark usually appears as a separate text element
- Click on the watermark text and delete it
- Go to File > Download > PDF Document
The whole process takes about 30 seconds per page. I tested it on a 12-page contract with “DRAFT” stamped diagonally across every page, and it worked perfectly. The watermark was gone, formatting stayed intact.
Where it falls apart
Google Docs reformats complex PDFs. Multi-column layouts, tables with merged cells, documents with precise positioning – these get scrambled during conversion. If your PDF has simple formatting (mostly text, basic headers), this method is unbeatable. If it’s a designed document with specific layout requirements, skip to Method 3 or 5.
Image watermarks sometimes survive the conversion. Google Docs treats them as inline images rather than separate layers, so they get embedded into the document body.
Method 2: PDF24 Tools (Best Free Online Option)
PDF24 is a German company that offers a massive suite of PDF tools, all completely free. No account required, no daily limits, no file size caps. I’ve been using it for about 8 months now and honestly it handles 90% of PDF tasks I throw at it.
How to remove watermarks with PDF24
- Go to PDF24’s Edit PDF tool
- Upload your PDF
- The editor loads each page visually. Click on the watermark element
- Hit Delete or use the eraser tool
- Download the cleaned PDF
PDF24’s editor treats PDFs as layered documents, which means it can usually isolate watermark elements from the actual content. In my testing, it successfully removed watermarks from 11 out of 14 test files. The three failures were all flattened PDFs where the watermark was baked into the page image.
Pros and cons
Pros: Completely free, no registration, handles large files, processes locally in your browser (files aren’t uploaded to their servers), works on any OS
Cons: The visual editor can be slow with 50+ page documents, can’t handle flattened watermarks, no batch processing
Method 3: LibreOffice Draw (Best Desktop Solution)
LibreOffice Draw might seem like an odd choice for PDF editing, but it’s actually one of the best free tools for this specific task. It opens PDFs as editable vector documents, which means every element – including watermarks – becomes a selectable, deletable object.
Step-by-step
- Open LibreOffice Draw (it comes with any LibreOffice installation)
- File > Open > select your PDF
- Each page opens in Draw with all elements as individual objects
- Click on the watermark. It should highlight with selection handles
- Press Delete
- File > Export as PDF
I was skeptical about this approach until I tried it on a 45-page technical manual with both text and image watermarks. Draw handled it without breaking a sweat. Every watermark was a separate object, easy to select and delete. The formatting stayed nearly perfect – just a few minor font substitutions on uncommon typefaces.
The catch
LibreOffice Draw opens PDFs one page at a time by default. For a 100-page document, that means repeating the process 100 times. There’s a workaround using macros, but it’s not beginner-friendly. For documents over 20 pages, PDFgear (Method 5) is probably a better bet.
Also, you need to download and install LibreOffice (about 350 MB). Not a big deal if you already have it, but worth mentioning if you’re looking for a quick online solution.
Method 4: Sejda (Solid Online Alternative)
Sejda is another online PDF editor that handles watermark removal well. The free tier gives you 3 tasks per day with a 200-page, 200 MB limit per file. That’s enough for most people’s needs.
How it works
Sejda’s approach is similar to PDF24 – you upload the file, it renders each page in an editor where you can select and delete elements. What sets Sejda apart is its “Whiteout” tool, which lets you draw white rectangles over watermarks. Not elegant, but effective when the watermark can’t be selected as a separate layer.
In my testing, Sejda’s element detection was slightly better than PDF24’s. It correctly identified watermarks as separate layers in 12 out of 14 test files, compared to PDF24’s 11. The difference came down to how each tool handles transparency – Sejda seems to parse PDF layer structures more aggressively.
Limitations
Three tasks per day on the free plan feels restrictive if you have a pile of documents to process. The paid plan ($7.50/month or $63/year) removes that cap, but at that price you might as well look at more full-featured options. Also, files are uploaded to Sejda’s servers, which matters if you’re working with sensitive documents.
Method 5: PDFgear (Best for Batch Processing)
PDFgear is a free desktop PDF editor that launched in 2023 and has gotten a lot better since. It runs on Windows, Mac, and iOS. No account needed, no feature restrictions, fully free.
Removing watermarks in PDFgear
- Open your PDF in PDFgear
- Go to Edit > Watermark > Remove Watermark
- PDFgear scans the document and identifies watermark layers
- Click Remove
Here’s the thing – PDFgear has a dedicated watermark removal feature. You don’t need to manually select and delete elements on each page. It scans the entire document at once and strips watermark layers automatically. For a 100-page PDF, this saves an enormous amount of time compared to the page-by-page approach in LibreOffice Draw.
I tested it on my full set of 14 PDFs. It handled text watermarks flawlessly across all files. Image watermarks worked on 10 out of 14 – the four failures were (again) flattened PDFs. The batch processing completed in under 10 seconds for a 78-page document.
What I didn’t like
The app pushes you to create an account during installation, though you can skip it. The UI feels a bit cluttered compared to dedicated tools like PDF24. And the automatic detection occasionally flags headers or footers as watermarks if they’re positioned similarly to typical watermark placements – just double-check before saving.
Method 6: Canva (Good for Designed PDFs)
Canva isn’t primarily a PDF tool, but its import feature works well for removing watermarks from visually designed PDFs like flyers, brochures, or presentations.
Upload your PDF to Canva, and it converts each page into an editable design. Watermarks become movable, deletable elements. The advantage over Google Docs is that Canva preserves visual layouts much better – graphics stay in place, fonts are matched, spacing is maintained.
The free Canva plan handles this fine. You’re limited to 5 GB of cloud storage and exports at standard quality, but for watermark removal neither of those matters. The 100 MB upload limit could be an issue for large PDFs with embedded images.
One warning: Canva rasterizes text in some cases. If you need the output PDF to have selectable, searchable text, verify the output before deleting your original. In about 4 of my 14 test files, Canva turned text into images during the conversion process.
Method 7: GIMP (Nuclear Option for Stubborn Watermarks)
When nothing else works – when the watermark is baked into the page, flattened, impossible to select as a separate layer – GIMP is your last resort. It’s not pretty, and you’ll lose text selectability, but it works on literally any watermark.
The process
- Open the PDF page in GIMP (it imports at whatever resolution you choose – I use 300 DPI)
- Use the Clone Stamp or Healing Tool to paint over the watermark
- For semi-transparent text watermarks, try Colors > Curves to adjust the watermark’s opacity until it disappears, then clean up any remnants
- Export as PDF
This is tedious work. A single page can take 5-15 minutes depending on how complex the content behind the watermark is. I only recommend this for one or two critical pages where other methods failed. If you need to clean 50 pages this way, it’s probably faster to recreate the document from scratch.

What About Python Scripts?
If you’re comfortable with code, Python’s PyMuPDF (also called fitz) library can remove watermarks programmatically. A basic script looks something like this: open the PDF, iterate through pages, find annotation or overlay objects matching watermark characteristics, delete them, save.
I wouldn’t recommend this route unless you’re already a Python user. The learning curve is steep for someone who just wants to remove a “DRAFT” stamp. But if you have hundreds of PDFs to process, scripting is the only sane approach. PyMuPDF handles about 50 pages per second on a modern machine.
Which Method Should You Use?
Here’s my decision tree after testing all of these:
- Simple text watermark, under 20 pages: Google Docs. Takes 30 seconds, you already have it
- Any watermark, want to stay online: PDF24 or Sejda
- Complex document, need precise formatting: LibreOffice Draw
- Large document or batch of files: PDFgear
- Designed PDF (brochure, flyer): Canva
- Absolutely nothing else works: GIMP
If you regularly work with PDFs, I’d suggest installing PDFgear as your go-to. It handles not just watermarks but most PDF editing tasks, and it’s completely free with no restrictions. For occasional one-off watermark removal, Google Docs or PDF24 will get the job done without installing anything.

FAQ
Is it legal to remove watermarks from a PDF?
It depends on who owns the document and what the watermark is for. Removing watermarks from your own documents (like “DRAFT” stamps on finalized files) is perfectly fine. Removing copyright watermarks from someone else’s content is illegal under DMCA and similar laws. Removing trial watermarks from paid software output is typically a terms-of-service violation. When in doubt, check the document’s license or ask the owner.
Can I remove a watermark from a password-protected PDF?
Not directly. You need to unlock the PDF first, then remove the watermark. If you know the password, most of the tools above let you enter it when opening the file. If you don’t know the password and you’re the document owner, tools like PDF24 or Sejda can remove permission restrictions (not open passwords) before you edit.
Will removing a watermark affect the PDF quality?
With methods 1-5 (Google Docs through PDFgear), no – the document quality stays identical because these tools edit the PDF structure without re-rendering the content. Method 6 (Canva) may rasterize text in some cases. Method 7 (GIMP) always rasterizes the page, reducing text quality and removing selectability. For best results, stick with PDFgear or LibreOffice Draw.
What’s the fastest way to remove watermarks from multiple PDFs at once?
PDFgear is the only free tool in this list with built-in batch processing for watermark removal. Open multiple files, apply the Remove Watermark function to each. For truly large-scale processing (hundreds of files), a Python script using PyMuPDF is faster – it processes about 50 pages per second and can handle entire directories in a single run.
Can AI tools remove PDF watermarks?
Some AI-powered image editing tools (like Photoshop’s generative fill) can remove watermarks from rasterized PDFs, but they’re overkill for this task and usually require paid subscriptions. For text-layer watermarks, traditional PDF editors are faster and produce cleaner results. AI makes more sense when dealing with complex image watermarks on photographic content.
