How to choose the right tool

Use PDF tools when your source is document-first and layout fidelity matters, and use image tools when your source is visual-first and pixel editing is the priority. For mixed workflows, convert or normalize files first, then run merge, split, compress, watermark, or OCR in a second pass.

The fastest way to avoid quality loss is to keep each step focused: convert once, edit once, and export once. Repeated re-encoding can degrade text, color, or scan readability, especially on small or compressed source files.

Processing quality and practical limits

• Output accuracy depends on source quality, embedded fonts, scan contrast, and document structure.
• For legal, finance, or compliance workflows, always verify final files before submission or sharing.
• If a document includes many mixed formats, run conversion first and then process in smaller batches for stable results.
