All three: Video Overviews (MP4/WebM), PDF reports, and PPTX slide decks. Each mode removes the watermark differently, video uses pixel reconstruction, PPTX strips the embedded watermark image from every slide, and PDF covers the region with a background-matched patch.
Yes. The removal region is fully adjustable, drag and resize it over the watermark, or start from the built-in presets for the current large and older small watermark.
No. Video runs through smart pixel reconstruction compiled to WebAssembly, and PDF/PPTX are edited in your browser, everything stays in your browser.
Roughly the length of the video on a modern laptop, a 3-minute Video Overview typically processes in a few minutes. PDF and PPTX are near-instant.
PPTX: yes, fully lossless, only XML references change. PDF: every pixel, glyph, and vector outside the patched region is untouched, and the patch renders at 3× resolution. Video: re-encoding is unavoidable for pixel reconstruction, so we use a visually-lossless H.264 setting (CRF 18) and copy the audio bit-for-bit.
Smart blend is generative fill, the watermark region is rebuilt from the surrounding pixels, invisible on clean or gradient backgrounds. Blackout stamps a solid box (any color) where you can overlay your own text or logo, the reliable choice for busy imagery.
