Standard and Advanced Modes — Frequently Asked Questions
What is the difference between Standard and Advanced modes?
Standard mode presents the essential processing steps. Advanced mode reveals additional tool-supported settings and, where available, source and result previews.
When should I choose Standard mode?
Choose Standard when default settings are sufficient and no additional processing adjustments are needed.
When should I choose Advanced mode?
Choose Advanced when the particular tool offers a relevant supported adjustment, inspection option or preview.
Which additional settings can I use?
Available controls depend on the operation; only controls connected to processing should be presented as output-changing settings.
How do source and result previews work?
A preview is displayed only when the browser or configured engine can render that file type. Preview-only display controls do not modify the exported file.
Will Advanced settings affect the downloaded file?
Processing settings affect the file only when wired to the active conversion engine. Preview-only settings change the on-screen view, not the output.
