Frequently Asked Questions
What file formats can I use for a signature logo in Adobe Acrobat?
Adobe Acrobat supports several common image formats for signature graphics, including JPEG, PNG, GIF, BMP, and single-page PDF files. Converting your logo to a PDF format often yields the best scaling results.
Why does my custom signature logo look pixelated or blurry?
Blurriness typically occurs when the imported image resolution is too low. Ensure you are using a high-quality, high-resolution graphic. Acrobat resizes the image to fit the signature field, so starting with a crisp image prevents pixelation.
Can I save multiple signature appearances for different purposes?
Yes. You can create multiple appearance profiles in the Preferences menu, each with a different graphic or text layout. When digitally signing a document, you can simply select the appropriate appearance from a dropdown menu.
How do I remove the Adobe Acrobat watermark from my digital signature?
To remove the default watermark, go to Edit > Preferences > Signatures > Creation & Appearance > More. Edit your current appearance profile or create a new one, and ensure you select 'Imported Graphic' or 'No Graphic' instead of 'Show Adobe Acrobat watermark'.
