Frequently asked questions
Does this tool send my input to AsKrs?
Most tool pages run directly in the browser and are designed for quick local work.
What should I check before copying or downloading the result?
Review the preview, file name, format, size, and any warning message first.
When should I recheck the source instead of trusting the first SMI to SRT Converter result?
Treat the first scan, decode, or inspection result as a candidate value until it matches the visible source, label, or symbol you can verify.
What part of the SMI to SRT Converter result should I carry into the next step?
Check whether the converted speech, transcript, or caption block is clear enough for the next step.
