Frequently asked questions

Yes. The browser editor and subtitle conversion tools can be used without a paid plan. You can edit, convert, check, and export subtitle files directly in the browser.

No account is required for the core local editing workflow. You can open a subtitle file, load a matching video or audio file, preview captions, edit text, adjust timing, and export the result directly in the browser.

No. The main editor reads subtitle and media files with browser APIs, so the file contents stay on your device during normal editing. The working session may be saved in local browser storage so a draft can recover after a refresh.

The main editor imports SRT and WebVTT files. It can export SRT, VTT, TXT, and CSV. Separate tool pages also support SRT to VTT, VTT to SRT, TXT to SRT, TXT to VTT, subtitle time shifting, and subtitle QA checks.

Yes. Load a local video or audio file alongside the subtitle track, then play the media to preview the active subtitle over the video area. Browser media support depends on the codecs supported by the current browser.

The waveform timeline helps you see where speech or sound activity happens. You can select subtitle cues, move cue blocks, and drag cue edges to adjust start and end times more quickly than typing every timestamp by hand.

Yes. For one subtitle, adjust the start and end time fields or drag the cue on the timeline. For a whole file that is consistently early or late, use the subtitle time shifter tool to apply a positive or negative offset.

Plain text does not contain real timing, so TXT conversion creates a structured subtitle draft from your chosen line, sentence, paragraph, duration, gap, and start offset settings. Review the result against the media before publishing.

The editor stores a local working session in your browser so recent draft data can often be restored after a refresh. Still, exporting your subtitle file is the safest way to keep a finished version or transfer work to another device.

The site is responsive and the tools can be opened on mobile browsers, but detailed subtitle editing is much easier on a larger screen with a keyboard, pointer, and enough horizontal space for the timeline.

No. Subtitle Editor does not directly generate or translate subtitles. It focuses on manual editing, timing, conversion, search, replacement, QA, and export. AI-generated or translated captions can still be imported for review and timing cleanup.

Desktop editors are often better for advanced broadcast workflows and very large projects. Subtitle Editor is designed for quick browser-based tasks: fixing captions, previewing timing, converting formats, checking readability, and preparing web or course subtitles without installing software.
