Full PDF editing: edit text directly, add watermarks, add page numbers or Bates labels, and run OCR on scanned documents.
Editing is where Konomic shines. Unlike most online tools that only let you add annotations, Konomic's editor lets you modify text directly, insert images, add signatures, apply watermarks, and make scanned PDFs searchable with OCR. All four tools work in the browser with EU-based privacy.

On clean printed documents at 300 DPI, accuracy is 95-99%. Lower quality scans, unusual fonts, or handwriting reduce accuracy. For best results, scan at 300+ DPI with good contrast.
Yes. The editor includes a signature tool where you can draw with mouse or finger, type with a signature font, or upload an image of your signature. Place it anywhere on the PDF.
Watermarks can be applied with custom opacity (0-100%). Use 30-50% opacity for draft markers that are visible but don't obscure content. Use 100% for permanent stamps.
