Best practices

PDF tools are best used when preserving layout matters. Check the output file before sharing important documents. For scanned PDFs, OCR quality depends on image clarity and text contrast.

Quick checklist

Confirm the input file, value, text, or measurement is correct before running the tool.
Use the visible dropdowns and settings to choose the output format, unit, quality, size, or result style.
Check the preview, result text, or downloaded file before using it for important work.
For private or sensitive data, prefer browser-based tools and avoid uploading files unless the tool clearly needs server processing.
