How does Smart Rotate PDF differ from standard rotation?

Smart rotation detects the content orientation of each page and proposes a correction. Standard rotation applies an angle that you explicitly choose for the whole file or each page. For a long document with mixed orientations, run smart detection first and manually review unusual pages.

Is automatic orientation detection always accurate?

No. Blank pages, image-only pages, tables, vertical text, seals, and pages with very little text can be difficult to classify. Compare the source and corrected page; download immediately when detection finishes, or manually adjust an incorrect suggestion first.

How many PDFs can Smart Rotate process in one batch?

You can add up to 20 PDFs with 500 pages total. Files are checked page by page in queue order. One valid result is exported as a PDF, while multiple valid results are collected into one ZIP.

Where are files processed, and what happens when one fails?

Parsing, orientation detection, previews, and export run locally in your browser without using cloud trial or daily quota. A failed file does not stop the remaining files; retry it, remove it, or explicitly skip it to continue.
