Yes, if they are stored as OCG layers or annotations. Text-based watermarks like "CONFIDENTIAL", "DRAFT", "REVIEW", or "SAMPLE" have a 40-50% success rate when properly structured as layers or annotations.

Image watermarks (company logos, overlays) are not supported in the free browser-based version. These require server-side processing with advanced tools like PyMuPDF.

Scanned PDFs have watermarks "flattened" into the image, making them impossible to remove without image processing. Our tool cannot remove watermarks from scanned or image-based PDFs.

Background patterns and repeated watermarks can only be removed if they are stored as separate OCG layers. If they are embedded in the page content, they cannot be removed by the free version.

Only if they are stored as OCG layers or annotations. Diagonal text watermarks that are directly embedded in the page content cannot be removed.

Transparent watermarks can be removed if they are in OCG layers or annotations. Embedded transparent watermarks are not supported.

Once the page is loaded, the tool can process files offline. However, you need an internet connection to initially load the tool.

Failure can occur with encrypted PDFs (need password first), flattened watermarks (part of document image), or very complex watermark designs. Try converting to different PDF version or using higher quality source.

Adobe Acrobat uses server-side processing with more advanced tools, supporting more watermark types. Our free browser-based tool supports OCG layer and annotation watermarks with 40-50% success rate, but is completely free and processes files locally for privacy.

Most "free" tools upload your files to servers, compromising privacy. Our tool processes everything locally in your browser, offering superior privacy while being completely free, though with limited watermark type support.

Key advantages: 100% free, no signup, client-side processing (privacy), batch support, works on all devices, no file limits. Limitations: Only supports OCG layer and annotation watermarks (40-50% success rate).

iLovePDF offers similar functionality but requires file uploads to their servers. Our tool is more private as everything happens locally, though with more limited watermark type support.

Desktop software may offer more features and higher success rates but requires installation and payment. Our tool is instant, free, and requires no installation, with limitations on supported watermark types.

For simple OCG layer and annotation watermarks, yes! Our free tool handles these cases. For embedded image watermarks, complex Form XObjects, or flattened watermarks, paid tools with server-side processing are recommended.

Try running the tool multiple times - some watermarks have multiple layers. If that doesn't work, the watermark may be flattened into the document image.

Large files or complex watermarks take longer. Try closing other browser tabs or processing smaller files separately.

Ensure the file is under 50MB and in PDF format. Some corrupted PDFs may not upload properly.

Check your browser's download settings. Some browsers block automatic downloads - adjust your settings if needed.

Ensure you're using a modern browser (Chrome, Safari, Firefox) and have JavaScript enabled.
