Why convert KEY to MD?

  • A converted copy keeps the original file intact for comparison and future edits.
  • The output can be tested in the destination workflow before the original is archived.
  • A separate copy makes it easier to compare the old and new behavior.
  • Conversion is useful when the destination has a strict format requirement.

Will quality change?

Office and PDF engines interpret layout differently. Check headers, footers, images, and tables after conversion. Review the file in the application where it will be used.

Processing and limits

Processing
Server-side
Engine
LibreOffice and document tooling
Maximum size
100 MB per file on the server.
Batch support
Yes, multiple files can be queued; completed results can be downloaded as a ZIP.
Quality controls
No quality slider. The output follows the fixed conversion path.

The file is processed on the server because the conversion requires a server-side engine or a utility operation.

  • KEY features without a direct Markdown equivalent may not survive the conversion.
  • Conversion cannot restore detail that the source format already discarded.
  • Complex, encrypted, or unusually structured files may need manual review.

Platform compatibility

The output is a Markdown file. Use an application or device that accepts that format, and test the result on the destination platform if compatibility is critical.

When not to convert

  • If Markdown support is uncertain on the destination device, test a sample before processing a large batch.
  • Do not use a converted file as the legal or signed original when signatures or metadata must be preserved.
  • Do not overwrite the source; keep both versions until the output has been approved.
