Clean up your entire SRT file at once
Kapwing's SRT Editor cuts down on repetitive cleanup that can introduce new errors. Search and replace recurring errors or update names, phrases, and keywords across your entire subtitle file at once. When you need to restructure captions, merge or insert subtitle lines and adjust characters per line without manually reformatting your SRT. This makes it easier to keep captions readable, match your audience’s reading speed, and prevent text from covering important parts of your video.
For larger captioning workflows, you can use Kapwing’s subtitle tools to generate, edit, translate, style, and add subtitles to video in one place. Whether you’re editing podcasts, training videos, or high-volume social media content, you can spend less time fixing caption files and more time getting videos ready to publish.
Make multi-speaker subtitles easier to follow
When a video has multiple speakers, viewers need to know who’s saying what. Kapwing’s SRT editor uses speaker tags to help you identify and edit dialogue by speaker, so you can keep conversations clear while reviewing your SRT file.
This is especially useful for interviews, panel discussions, podcasts, tutorials, and other videos where speakers trade off frequently. Instead of treating every subtitle as an isolated line of text, you can edit with the conversation in context and create captions that are easier to follow from one speaker to the next.
Keep subtitles consistent across every video
Standardize subtitles across videos, courses, campaigns, and content libraries without manually checking the same details every time. Kapwing gives teams control over terminology, timing, and caption styling, so subtitles stay consistent as you create more content.
Add brand names, industry terms, and preferred spellings to your Brand Glossary to help keep terminology consistent across future subtitle edits. Fine-tune timecodes for precise caption timing, then choose from a library of fonts — including clear, easy-to-read sans serif options — to keep subtitles readable and aligned with your brand.
From SRT file to subtitled video in 100+ languages
Edit your SRT file, translate subtitles into 100+ languages, and add them to your video in one place. Review subtitles alongside your video as you work, so you can fix text and timing in context without switching between text editors, media players, and translation tools.
Make subtitles easier to read and match your brand with Kapwing’s subtitle tools, including 100+ preset styles and custom fonts, colors, backgrounds, animations, and speaker-specific styling. When you’re done, export as SRT, VTT, or TXT, or hardcode subtitles directly onto your video for a version that’s ready to share.

Frequently Asked Questions
We have answers to the most common questions that our users ask.
Is Kapwing's SRT File Editor free?
Yes, the SRT File Editor is free to try. Upgrading to a Pro Account increases your auto-subtitling limit to 300 minutes per month and unlocks features like the Brand Kit and custom fonts.
Is there a Kapwing watermark on exports?
If you are using Kapwing on a Free account then all exports — including the SRT File Editor — will contain a watermark. Once you upgrade to a Pro Account the watermark will be completely removed from all your subtitled videos.
What is an SRT file?
An SRT file (short for "SubRip Subtitle file") is a popular subtitle format that contains the text of what’s being said in a video, along with the timing and order in which the subtitles appear. The SRT file format is a plain text file that must be used alongside the video file to display captions.
While there are more advanced file formats that allow for custom caption style and positioning, SRT files remain extremely popular because of their simplicity and broad compatibility with video platforms. When working with an SRT file on Kapwing, you can still achieve custom positioning and stylization, too, since the editor automatically hardcodes final subtitles into your video when you export.
How do I create a SRT file?
You can create an SRT file for subtitles on PC by using the Notepad feature, or on Mac by opening TextEdit. However, these applications require you to manually input subtitle numbering or timecodes, which is tedious and time-consuming. For a more streamlined experienced, open Kapwing and select the "Subtitles" feature in the left-hand toolbar. Generate subtitles or manually type them into the editor, then download an SRT file instantly.
How to modify the timing on an SRT file
There are a couple ways to modify the timing on an SRT file. The first is a manual process, which requires using a plaint text editor like Notepad on PC or TextEdit on Mac. Every line of subtitles in an SRT file should have start and end timecodes, formatted as "00:00:00,000" (representing 0 hours, 0 minutes, 0 seconds, and 000 milliseconds). You'll need to watch the video and modify the timecodes to match it properly.
However, you can skip over this tedious process by using Kapwing's SRT File Editor, which provides you with an easy-to-adjust playhead, a chars-per-subtitle slider, and a one-click button beneath timecodes to set a subtitle line to the current playhead time. This greatly simplifies and accelerates the process of modifying the timing on an SRT file.
How to extract SRT file from video
It's possible to extract an SRT file from a video online for free. While there are a range of online applications to help you do this, Kapwing's online studio stands out by allowing you to easily extract an video's spoken content as text, edit it word-by-word and perfect timing in one simple location, and then download a polished SRT file.
What does it mean to hardcode subtitles?
When you hardcode subtitles, you embed them directly into a video file, making them permanently visible during playback and unchangeable. Once hardcoded, the subtitles become part of the video, similar to a watermark or overlay, and cannot be turned off or adjusted. In other words, it’s like "burning" the subtitles onto the video — once they’re hardcoded, they stay there. They remain visible no matter what device or video player is used.
What are SDH subtitles?
SDH refers to subtitles specifically designed for individuals who are Deaf or hard of hearing (hence "SDH" = "Subtitles for the Deaf and hard of hearing"). These subtitles not only capture spoken dialogue but also provide additional details like sound effects, music, and identification of speakers, assuming the viewer cannot hear the audio.
How to edit SRT sub files
You can edit SRT sub files using in-built plant text applications like TextEdit on Mac and Notepad on PC. You simply open the SRT file in the plain text editor, locate the section(s) you want to modify, and correct typos, add text, adjust timecodes, etc.
For a more user-friendly, streamlined experience, open your SRT sub file in Kapwing's SRT File Editor, where timecodes can be matched to the playhead's position on your accompanying video in one-click. You can easily correct typos, add or merge lines, and even hardcode your subtitles into your video with customized positioning, fonts, colors, and animations.
What is video accessibility?
Video accessibility is the process of creating video content that is accessible to everyone, including individuals with disabilities. The purpose of making video accessible is twofold: it both promotes a more inclusive experience for viewers and helps creators access a larger audience. By bridging the gap for viewers who need accommodations due to hearing or vision loss, you ensure that everyone has equal access a video's information (or entertainment).
An example of an accommodation created for hearing loss is subtitles or captions, since they reproduce spoken content or environmental noises in visible text that viewers can read. On the other hand, choosing high contrast colors for subtitles/captions like blue and orange or black and white can help those with partial loss of vision read text more easily.
