File Conversion Quality Guide
Conversion quality is always a trade-off between file size, visual fidelity, compatibility, and processing time. Use this guide to choose stable defaults.
Video compression
Start with H.264, CRF 23, fast/medium preset. Move to stronger compression only if upload targets still reject file size. Test subtitle readability before final export.
Image conversion
Use JPG for photos, PNG for transparency or sharp UI graphics, and WebP for modern web delivery. Avoid upscaling low-resolution sources.
OCR extraction
High contrast, straight alignment, and sufficient resolution are required for reliable OCR. Always proofread extracted numbers, names, and legal terms.
