Can I edit existing text in the PDF?

Why is the editor running slow on large files?

Since all rendering happens in your browser, extremely large files (50MB+) might require more RAM than some devices have available.

Is the editor compatible with touchscreens?

Yes, we have optimized the canvas controls for both mouse and touch input on tablets and smartphones.

Are there any watermarks?

No. PDF MASTER TOOLS does not add any branding or watermarks to your edited documents.
