Common problems
Fixes for the issues we see most often across PDF, Word, Excel, and OCR conversions.
Copied text from PDF is gibberish
The PDF uses a custom-encoded font subset without a /ToUnicode mapping.
Excel dates are off by four years
You imported a file saved on macOS Excel 2008 or earlier — it uses the 1904 date system.
Formatting is lost after PDF → Word
The PDF was not tagged, so paragraph and heading structure had to be inferred from geometry.
OCR drops Slovak/Czech diacritics
The language pack is set to English-only.
Conversion is slow on large files
All processing runs in your browser. Big files mean long CPU work.
