Are my files stored after conversion?
▼

Can I convert PDF to Word?
▼
Yes, PDF to DOCX conversion is supported. Text and basic formatting convert well, but complex layouts, custom fonts, and tables may require manual adjustment after conversion.
Will image quality be preserved?
▼
You control quality settings. Choose 90-100 for minimal loss, 70-80 for good compression, or 50-60 for maximum file size reduction. PNG conversions are lossless by default.
Can I resize images during conversion?
▼
Yes, set maximum width and height dimensions in the conversion options. Images will be proportionally resized to fit within those limits while maintaining aspect ratio.
Why did my Excel formulas become values in CSV?
▼
CSV format doesn't support formulas—it only stores values. The converter calculates formula results and exports those values. For formula preservation, keep files in XLSX format.
Is batch conversion available for all formats?

Troubleshooting Common Issues
Issue: Converted image quality is poor
Solution: Increase the quality setting (80-95) for lossy formats like JPG and WebP. For PNG, quality affects compression level. DOCX to PDF should maintain quality—issues may be in the source.
Issue: PDF to Word conversion formatting issues
Solution: PDF to DOCX conversion preserves text but complex layouts, tables, and custom fonts may not convert perfectly. For critical documents, review and adjust formatting after conversion.
Issue: Excel formulas lost in CSV conversion
Solution: CSV format doesn't support formulas—only values are exported. For formula preservation, keep as XLSX or use JSON format which can include calculated values.
