PDF processing boundaries
These tools operate within browser memory and the capabilities of the browser PDF libraries used on this page. Encrypted, malformed, scanned, XFA, unusual forms, complex signatures, OCR-dependent documents, and advanced desktop-editor features can require specialist software. Always verify generated files before discarding the source.
How to use this Add Image to PDF

How it works
The PDF page is rendered in the browser for positioning, while the downloaded output is written as PDF content with browser-side JavaScript libraries. Source files are not uploaded to WebToolArc.
