Formula or method
Normalize cue numbering, timestamp arrows, blank lines, and timestamp orderingAssumptions
- Repairs cover common structural problems and do not rewrite caption wording.
- Malformed or empty cues are omitted with line diagnostics; inspect partial results before publishing.
- SRT output omits WebVTT positioning, style, and metadata blocks.
Sources and verification
- YouTube Help: Supported subtitle and closed-caption filesLists supported caption formats and identifies SubRip as an approachable option for creators new to caption files.
Try it: repair a subtitle timestamp arrow
Our three-cue practice file starts with the wrong cue number and uses a short arrow. The repair restores SRT structure while keeping the caption wording.
- Download camera-tips-broken.srt and load it in the tool, or paste the first cue shown below.
- Select Validate and repair. Inspect the line diagnostics and the three-cue preview.
- Download the repaired SRT and compare it with the original before replacing a delivery file.

00:00:02,000 --> 00:00:04,000
Keep the camera steady.The full sample should produce three cues with the same text and times. If your own file produces fewer cues, inspect every omission diagnostic: the checker cannot reconstruct missing words or safely guess invalid timing.
If your result looks different
The output has fewer captions
Look for malformed timestamps, an end before the start, or empty cue text at the reported lines. Correct those blocks in the source and run the check again.
The file is valid but captions appear at the wrong time
Structural repair does not synchronize speech. Compare the first and last captions against the video; use a fixed time shift only if the mismatch stays constant.
After structural repair, find cues that need more reading time or better line breaks.
Check subtitle reading speedHow to use the srt validator
Parse an SRT file locally, normalize cue numbering and timestamp arrows, and return a structurally consistent file. Repairs are deterministic and preserve cue wording; they do not proofread language, judge timing quality, or certify platform acceptance.
Review what the repair changed
Load or paste a copy of the subtitle file, then compare the repaired output with the original before replacing anything. The tool renumbers parsed cues, normalizes timestamps, restores cue separation, and keeps arrows that belong to spoken text rather than treating every arrow as timing syntax.
Malformed timestamps or blocks with no recognizable cue range may be omitted because they cannot be repaired safely. Keep the source file until the corrected version has been reviewed in a player against the final video.
Keep local processing and timing limits clear
Subtitle text is read and processed in the browser; the tool does not upload the selected file. File and character limits protect the page from unbounded local work. Avoid loading confidential transcripts on a shared device and delete downloaded copies according to the project policy.
A structurally valid SRT can still be hard to read or mistimed. Follow the repair with the reading-speed checker and a manual playback review for line breaks, speaker changes, sound descriptions, synchronization, and meaning.
Questions about this tool
Will the repair change subtitle wording?
It is designed to preserve cue text while normalizing structure. Always compare the output with the original because severely malformed blocks may not be recoverable.
Are subtitle files uploaded to Free Creator Toolkit?
No. The current tool reads and processes the file in your browser. The page still applies local file-size and character limits.
Does a repaired file guarantee YouTube acceptance?
No. It improves basic SRT structure. Encoding, unsupported styling, language metadata, timing, and platform-specific validation may still require review.
