Tips for File Conversion

• Check file size limits: Free tools usually have size limits (often 10-100MB). For larger files, you might need to pay or use desktop software.
• Be patient: Large files take time to convert. Don't close the browser.
• Check the output: Sometimes conversions aren't perfect. Check the converted file before deleting the original.
• Use original software when possible: If you have Microsoft Office, use its built-in PDF export - it's usually better quality.
• Privacy: Don't upload sensitive files to online converters. Use desktop software for sensitive documents.

Image format conversion: Convertio or CloudConvert

Document to PDF: Use the original software (Word, Excel, etc.) - it's usually better quality

When to Use Desktop Software

Online converters are great, but sometimes you need desktop software:

• Large files (over 100MB)
• Batch conversions (many files at once)
• Sensitive documents (privacy concerns)
• Advanced options (custom settings)

Free desktop options:

• HandBrake: Video conversion (free, open source)
• GIMP: Image editing and conversion (free)
• LibreOffice: Document conversion (free, open source)
