About this tool
Use it for draft labels, internal documents, sample files, or ownership marks.
This conversion needs server processing because PDF and Office files often require dedicated document engines.
Common use cases
Add Watermark is useful when file format rules get in the way of online forms, email attachments, client documents, school submissions, web publishing, archiving, or quick office cleanup.
For best results, use a clean source file, check the converted output before sharing it, and keep a copy of the original file if the document is important.
Privacy and file handling
Some formats require a document engine on the server. FileForma keeps that workflow temporary: files are processed for the requested task and scheduled to expire after 30 minutes.
Do not upload files you do not have permission to process, and avoid using any online converter for highly sensitive records unless your organization allows it.

Use it for draft labels, internal documents, sample files, or ownership marks.
What kind of PDF files work best?
Clean, unlocked PDF files usually convert best. Scanned documents, heavy graphics, unusual fonts, or password protection can affect the result.

Yes. FileForma works in modern mobile browsers, so you can convert files from a phone, tablet, laptop, or desktop computer.
Will the result always match the original perfectly?
Most common PDF tasks are reliable, but complex layouts, scanned pages, locked files, or unusual Office formatting may need a quick review after conversion.
