Frequently Asked Questions
What formats can I convert SUB to?
You can convert SUB files to SRT. Select your target format after uploading your file.
Is this converter safe to use?

Can I convert multiple files at once?

Is there a file size limit?
Browser-based conversions depend on your device's memory. Most devices handle files up to 50MB without issues.
Is this SUB converter free?
