Common Problems an Audio to SRT Converter Solves
Subtitles make videos watchable on mute, easier to follow for non native speakers and accessible to viewers who are deaf or hard of hearing. Making them by hand is another story. Typing every line, then dragging each caption to the right in and out point, can take longer than the edit itself. Turning the soundtrack into timed captions automatically removes the slowest part of the job, so you review instead of building every caption from scratch, and every video you publish can carry subtitles, not only the ones you had time for.
- Typing every line and setting each in and out point by hand
- Captions that are too long to read before they disappear
- Subtitles that drift out of sync after a trim or an intro change
- Different platforms asking for SRT or VTT, never the same file
- Paying again every time a video needs captions in another language
What You Get with the EzTranscriber Online SRT Generator
Subtitles that are timed, readable and ready for any player, from one upload.
Timed to the Spoken Word
Each caption starts when the phrase starts and ends when it ends, so viewers read along with the speaker instead of a second behind.
Readable Caption Length
Choose 32 or 42 characters per line and one or two lines per caption. Long sentences are spread across captions so no line runs past your limit.
Maximum Caption Duration
Cap how long a single caption stays on screen so fast talkers never produce a wall of text that viewers cannot finish reading.
Live Caption Preview
Watch the captions play over your audio or video before you download, and catch a wrong word or an awkward break in seconds.
SRT and VTT Downloads
Download standard SRT subtitles for YouTube, Premiere Pro and VLC, or a VTT track for web players, from the same transcript.
99 Languages and Translation
Transcribe the original language automatically, then translate the transcript and download subtitles for a second audience.
How to Convert Audio to SRT in Three Steps
From a raw MP3 or MP4 to a finished subtitle file, without opening a timeline editor.
- 1
Upload audio or video
Sign in, then drop in an MP3, WAV, M4A, MP4, MOV, MKV or WEBM file, or paste a direct media link. Most videos are converted to audio in your browser first, which keeps the upload small and fast.
- 2
Set caption length and timing
Choose characters per line, one or two lines per caption and the longest time a caption may stay on screen. Add a global offset if your video has an intro that is not part of the audio track.
- 3
Preview and download SRT or VTT
Play the captions over your media, fix any word the AI misheard in the subtitle editor, and download the subtitles. Upload them to YouTube, drop them into your editor, or keep the transcript for a translation later.
Four Features of Our SRT Generator
Everything between a recording and a subtitle file you can publish with confidence.
Preview Captions Before You Download
Most tools hand you a file and hope for the best. EzTranscriber shows the captions playing over your video, or under your audio, line by line, the way viewers will read them. Spot a caption that flashes by too quickly or a misheard product name, fix the text, and only then download. The preview uses the same timing as the export, so the rhythm you check is the rhythm your audience gets on a laptop, a television or a phone.
Preview My CaptionsControl Caption Length and Line Breaks
Broadcasters often use 32 characters per line, while web video usually allows 42. Pick the width, choose one or two lines, and set a maximum caption duration. EzTranscriber then spreads long sentences across captions within those limits and flags any caption that runs long or reads faster than 20 characters per second. Short social clips look clean on a phone, and long lectures stay comfortable to follow for an hour. Change a setting and the preview updates instantly, so settle the layout first and fix the wording after, because a new layout rebuilds the captions.
Set Caption LengthFix Timing with a Global Offset
Exported the audio without the five second intro? Added a title card after the fact? Shift every caption forward or backward with one offset value instead of nudging hundreds of lines by hand. The same control fixes your captions when the video is trimmed at the start. It moves in steps of a tenth of a second and applies to the VTT download in exactly the same way.
Adjust the TimingMP3 to SRT and MP4 to Subtitles in 99 Languages
Use it as an MP3 to SRT converter for a podcast episode, or upload a Zoom recording or an MP4 straight from your camera, and get subtitles in the language that was spoken. Then translate the transcript and download captions for a second market, with every timestamp kept in place. For a full written version of the same file, use MP4 to text or MP3 to text instead.

An SRT file is plain text: a number, a start and end time, and one or two lines of caption, separated by a blank line. That simplicity is why almost every video editor, player and platform accepts it. You can open the download in Notepad or TextEdit to make a last minute change before you publish. A VTT file carries the same captions with a WEBVTT header, dots instead of commas in the times and optional voice tags for speaker names.

Who Turns Audio to Subtitles with EzTranscriber?
Anyone who publishes video and wants it to be watched with the sound off.
Social Media Teams
Most social video is watched on mute. Short captions with 32 characters per line read well on Reels, Shorts and TikTok, and keep the hook visible in the first second.
Course Creators and Teachers
Caption every lesson for accessibility, and give students a VTT track that works in any web player or learning platform. Searchable captions also help learners jump back to a key point.
Video Podcasters
Turn the episode MP3 to subtitles for the video version, then reuse the same words for show notes and clips with the podcast transcript generator.
Localization Teams
Start from a correctly timed source file, then translate the audio and deliver subtitles in a new language without re-spotting every line.
Accessibility Officers
Meet captioning requirements for public videos, town halls and recorded events with files that can be reviewed, corrected and archived alongside the original media.
What Creators Say About Our SRT Generator
I caption every YouTube upload now. The preview is the best part: I catch the one wrong brand name before the file goes live instead of after a viewer points it out.
Marco Silva
YouTube Creator
We cut 30 second clips for Reels every day. Setting 32 characters and one line gives us captions that look great on a phone with zero manual line breaking.
Hannah Lee
Social Media Manager
Our course videos needed VTT captions for the learning platform. One upload gave us both SRT for editing and VTT for the player, perfectly in sync.
David Okafor
Instructional Designer
The offset control saved a whole project. The client added an intro after we had captioned everything, and I fixed the timing in ten seconds.
Sofia Rossi
Freelance Video Editor
We publish a video cut of every episode. Uploading the MP3 gives us captions for YouTube and a clean transcript for the show notes in one pass.
Ahmed Khan
Podcast Producer
Starting from well timed English captions means our translators only translate. Nobody re-spots the timings anymore, which used to cost us a day per video.

Localization Lead
SRT Transcription FAQs
Quick answers about subtitle files, caption length and exports. Still need help? Write to our support team.
What is an SRT file?
SRT (SubRip Subtitle) is the most widely supported subtitle format. It is a plain text file where every caption has a number, a start and end time like 00:00:01,250, and one or two lines of text.
How do I convert audio to SRT?
Sign in, upload your audio file or paste a link, set the caption length, and click Transcribe. When the transcript is ready, preview the captions and download the SRT. The whole job usually takes a few minutes.
Can I convert video to SRT or MP4 to SRT?
Yes. Upload MP4, MOV, WEBM or MKV video and EzTranscriber transcribes its soundtrack, so you get an AI video to SRT file without exporting the audio yourself. It works as an MP4 to SRT converter for screen recordings, webinars and camera footage alike.
How do I make an SRT file from an MP3?
Upload the MP3, choose your caption settings and download the result. Creators convert MP3 to SRT this way for podcasts, audiograms and any video that reuses the same audio track, and you can just as easily get an SRT from MP3 recordings of talks and webinars.
What caption length should I use?
For web and YouTube, 42 characters per line and up to two lines is a common choice. For phones and social clips, 32 characters and one line reads better. Keep each caption on screen for no more than six or seven seconds.
Can I edit the subtitles before downloading?
Yes. The subtitle editor lets you correct the text of any caption and flags captions that are too long or read too fast. Choose your caption length first, because changing it rebuilds the captions and clears earlier edits. Your text fixes and the global offset carry into both the SRT and VTT downloads, and you can copy the SRT in one click.
Should I download SRT or VTT?
Use SRT for YouTube, Premiere Pro, DaVinci Resolve and desktop players. Use VTT for websites and HTML5 video players. Both come from the same transcript, so there is no need for a separate VTT converter.
Can I create subtitles in another language?
Yes. The original language is detected automatically across 99 languages, and you can translate the transcript to create subtitles for a new audience with the timing kept intact.
How do I add an SRT file to YouTube?
In YouTube Studio, open the video, choose Subtitles, add a language, then pick Upload file and select the SRT. If the video is already on YouTube, the YouTube subtitle downloader is the faster route: paste its link and the SRT is made from the audio, no file needed.
Can I make subtitles for song lyrics?
Music players and karaoke apps usually expect timed lyrics in an LRC file rather than subtitles. Use the LRC generator to sync lyrics line by line, and keep SRT for the music video itself.
Are my recordings private?
Yes. Your audio, SRT and VTT files belong to your account, travel over an encrypted connection and are never published or shared with other users.
Is this audio to SRT file generator free?
Signing in is required, and every new account gets free credits to try it on your own files. After that you pay only for the minutes you transcribe; see pricing for plans and credit packs.
