Frequently Asked Questions

Everything you need to know about using DocuClean for PDF processing.

What types of watermarks can DocuClean remove?
DocuClean can remove text-based watermarks such as “DRAFT,” “CONFIDENTIAL,” “SAMPLE,” and any custom text overlays embedded in PDF documents. Our AI-powered engine detects both diagonal and horizontal watermark patterns. It also removes background colors and noise that may obscure your document content. For best results, enter the specific watermark text in the keyword field.
Is DocuClean really free to use?
Yes! DocuClean is completely free for all core features including watermark removal, PDF merging, splitting, and compression. There are no hidden fees, no sign-up required, and no limits on the number of files you can process. We sustain the service through minimal, non-intrusive advertising.
Are my files safe and private?
Absolutely. Your privacy is our top priority. Files are transmitted over encrypted HTTPS connections and are automatically deleted from our servers immediately after processing. We never retain, store, or share any uploaded documents. No data is ever sold to third parties.
What is the maximum file size I can upload?
DocuClean currently supports PDF files up to 15MB in size. This covers the vast majority of documents including reports, academic papers, contracts, and presentations. If your file is larger, consider using our built-in compression tool first, or splitting the document into smaller sections.
How does the PDF merge feature work?
Simply switch to the “Merge” tab, upload two or more PDF files, arrange them in your preferred order using drag-and-drop, and click “Merge & Download.” The merged document preserves all formatting, bookmarks, and original quality from each source file. It is perfect for combining report chapters, merging scanned pages, or consolidating multiple documents into one.
Can I use DocuClean on my phone or tablet?
Yes! DocuClean is fully responsive and works seamlessly on smartphones, tablets, and desktop computers. Whether you are using Chrome, Safari, Firefox, or Edge on any device, you will get the full functionality. You can even install DocuClean as a Progressive Web App (PWA) on your phone home screen for quick, app-like access without needing to download anything from an app store.
Will removing watermarks affect the quality of my PDF?
DocuClean is designed to preserve the original quality of your document while removing only the watermark elements. Text clarity, images, fonts, and page layout remain intact. Our engine works at the vector level, targeting only the specific overlay elements without re-rendering or compressing the underlying content. You can preview the result before downloading to ensure the output meets your expectations.
