FAQs about How to Add Logo to PDF
What image formats are supported when I add logo to PDF?
PDNob PDF Watermark Editor accepts common logo file formats including PNG, JPG, and JPEG. PNG is recommended because it supports transparent backgrounds, which lets your logo blend naturally into the PDF without a white box around it.
Can I add a logo to every page of a PDF at once?
Yes. PDNob applies the logo watermark across all pages of your PDF in one operation, so you do not need to stamp each page individually. This makes it practical for multi-page reports, contracts, and presentations.
How do I make the logo watermark semi-transparent?
Use the opacity slider in the watermark settings panel. Reducing opacity lets the underlying text and graphics show through, giving your logo a subtle watermark appearance without obscuring the document content.
Will adding a logo change the file size significantly?
A small logo image typically adds only a minor increase to the overall PDF file size. Using a compressed PNG or a logo optimized for screen resolution keeps the final file lean while still displaying your brand clearly.

Can I position the logo in the corner rather than the center?
Yes. The position control lets you place the logo anywhere on the page — top-left, top-right, bottom corners, center, or a custom coordinate — so it fits naturally with your document layout.
Is it safe to upload confidential PDFs to add a logo online?
PDNob uses SSL encryption during file transfer and automatically deletes uploaded files after processing. Your document content is never stored, shared, or used for any other purpose.
Does the logo watermark affect the original text or images in the PDF?
No. PDNob overlays the logo as a separate layer without modifying any existing content. Fonts, formatting, embedded graphics, and hyperlinks all remain exactly as they were in the original file.
What is the maximum PDF file size I can upload to add a logo?
The online tool supports PDFs up to 15 MB. For larger documents, the PDNob desktop application handles files up to 100 MB and offers additional branding and editing features.
