Common questions about Remove PDF Watermark and client-side processing

Watermarks created with Compixor are tagged with structured marked content (/Artifact /CompixorWatermark). When removing, our engine strips the dedicated watermark stream while leaving every original page content stream 100% byte-identical.
Yes. You can use our Targeted Text Matcher to strip matching text operators from the PDF stream, or the Interactive Erase Box tool to vector-redact watermark blocks.
