Optimize PDF

Typical compression reduces file size by 40-80% depending on content. Image-heavy PDFs compress the most. Text-only documents compress less because they're already efficient.

The Recommended level provides the best balance — virtually imperceptible quality loss on text and images. Maximum compression may show slight artifacts on photos. For critical documents, compare Original vs compressed before deciding.

AI upscaling uses machine learning models to generate sharper versions of low-resolution images. Unlike simple bicubic resizing, AI fills in details intelligently. Works best on photos with clear subjects.

The legal use of watermark removal depends on your rights to the content. Only remove watermarks from content you own or have explicit permission to modify. Konomic provides the technical tool — users are responsible for compliance with copyright law.

No. Compressed PDFs remain valid and work in any reader. Embedded fonts are preserved (as subsets), bookmarks stay intact, and digital signatures — if present — are preserved when using lower compression levels.
