Edit subtitles online with EasySub: correct the words, sync captions with speech, adjust their appearance, and export a subtitle file or a captioned video. Start with an existing subtitle file or generate a draft from video, audio, or any YouTube/video URL. Continue editing in the same project instead of moving between separate transcription, translation and video tools.

How to edit subtitles online
- Open your video and subtitles. Create or open a project in the EasySub workspace. Upload your video or audio, paste a YouTube/video URL, or bring an existing SRT subtitle file into the project. For automatic generation, select the language actually spoken in the recording.
- Correct the subtitle text. Select a caption and edit its wording while checking the video. Fix names, numbers and missing words, then refine punctuation and line breaks. Keep the meaning of the speaker's original sentence.
- Adjust start and end times. Replay the relevant section and use the subtitle timing controls to align its appearance with the speech. Check neighboring captions as well as the line you changed so one correction does not create an overlap.
- Set the subtitle style. Choose the font, size, color, position, background and outline for the video. Preview short and long lines with the same settings, particularly when your video includes a translated second line.
- Save, preview and export. Confirm your changes are saved. Download the edited subtitles as SRT, VTT, ASS or TXT, or export the video with subtitles visible. Play the result in the destination player before publishing.
Edit the wording without losing the context
A subtitle editor is useful even when an automatic transcript is mostly correct. A name, a measurement or a missing negative can change a sentence's meaning. Listen to the complete exchange, correct the caption, and replay it before moving on. For interviews, lessons and product demonstrations, use the same spelling for repeated names and specialist terms throughout the project.
Break long captions at natural phrases so each line is easy to follow. Keep important words together rather than splitting a name or a short phrase across two lines. Review captions with sound muted too: the text should still make the dialogue understandable.
Sync subtitles with the video
When a caption appears too early, move its start to the beginning of the corresponding speech. When it disappears too soon, review its end time and the next caption together. If timing drifts across a longer recording, check the beginning, middle and end instead of assuming the opening correction fixes every line.
Illustrative timing example: a sentence is spoken from 00:12.400 to 00:15.100, but its caption starts at 00:11.800. Moving that caption's start to 00:12.400 corrects the early appearance; then replay the transition to the next caption. These numbers demonstrate the editing process, not a benchmark or a customer result.
Style subtitles for a readable video
Adjust the font family and size, text color, outline, background and position to suit the video. Use a consistent style across the project and inspect captions over both light and dark scenes. A style that works on a short sentence may wrap differently on a long one, so preview more than the first frame.
For vertical video, check the caption placement in a phone-sized view. For bilingual subtitles, review the source and translated lines together and leave room for both. If you already have an approved subtitle design, reuse its settings rather than changing the font or size simply because the language changes.
Choose a subtitle file or a captioned video
Export editable text and timecodes for common video platforms and editors. Use the destination player to control the final appearance.
Download timed captions for workflows that accept WebVTT, including web video players.
Choose the styled-subtitle format for compatible subtitle and video workflows. Check how the receiving player renders the result.
Get the edited wording as plain text without subtitle timestamps, useful for a transcript or review document.
Want viewers to see your chosen design consistently? Export a video with the subtitles rendered on the picture. A separate SRT file carries text and timing; it does not preserve the full visual design shown in the editor. Keep a subtitle-file copy when you also want an editable version.
Generate, edit and translate in one workflow
EasySub supports more than 150 languages across its subtitle generation and translation workflow. For a new recording, automatic source subtitles can reach over 90% accuracy with clear audio. Free accounts receive a fixed 30 minutes of processing each month. You can refine the resulting text, timing and style in the subtitle editor.
When you need another language, use Add translation and review the translated track alongside the source. Projects with translation let you download Source only, Translated only or Bilingual subtitles. Review names, meaning and line length in each language before delivery.
For more detail, see the automatic subtitle generator, subtitle translator and subtitle download workflow. Use Add SRT to MP4 when your next step is putting an existing subtitle file onto a video.
Before you publish your edited subtitles
- Check names, numbers and meaning against the original recording.
- Replay caption transitions to spot early starts, abrupt endings and overlaps.
- Inspect long lines and bilingual captions for wrapping or obstruction.
- Confirm the saved project and exported file contain your final corrections.
- Test the chosen language, subtitle format and video style on the actual destination.
