SRT validator
Paste or upload an .srt file and get a precise list of what is wrong: numbering gaps, timing overlaps, cues that end before they start, overlong lines, reading speed above comfortable limits and encoding damage — each with the exact line number.
Everything runs in your browser. Your file is never uploaded to a server.
How it works
Paste or upload your .srt
Paste subtitle text or upload a file. Nothing leaves your browser.
Read the issue list
Every problem is listed with its severity, line number and details — errors break playback, warnings hurt readability.
Fix and re-check
Fix the issues in your editor, paste the file again, and repeat until the list is clean.
Making the subtitles is the hard part
These tools patch finished subtitle files. If you edit in Adobe Premiere Pro, the SmartCaptions extension generates, translates and styles Hebrew, Arabic and English captions directly in your timeline.
