About SRT Merger
A small, focused tool for people who care about subtitles.
Our mission
Subtitles decide whether a film is understood and enjoyed. Yet the tools for working with them are often heavy desktop programs, or websites that ask you to upload your files to a server you know nothing about. Our mission is simple: make the everyday jobs of subtitle work quick, private and free.
SRT Merger started with a single recurring problem. Two translations of the same film each had strengths. One had better phrasing, the other had the missing lines. Combining them by hand meant scrolling two text files and copying lines across, and it was easy to make mistakes with timecodes and numbering. A tool that aligns the files by time and lets you click the better line is faster and far less error-prone.
What we do
- A browser tool. The SRT Merger tool compares two .srt files and saves one merged file.
- Plain-language guides. Our subtitle guides explain formats, timing, encoding and translation review, so you understand what the tool is doing and can solve problems it cannot.
Principles we follow
Privacy by design
Your files are processed in your browser and never uploaded. We built it that way so there is nothing to protect, store or leak. Read how we handle data.
Honest documentation
We say what the tool does and what it does not do. It supports .srt files, expects UTF-8 and assumes your files are already in sync, and the tool page lists these limits plainly.
Useful content, written for people
Each guide is written to help someone finish a real task, from fixing a drifting subtitle to choosing a file format. We update guides when we find mistakes or when conventions change. If you spot an error, tell us.
Credit to the open-source project
The comparison and merging logic is adapted from srt-merger by machinewrapped, released under the MIT License. We have rebuilt the interface, added drag and drop, sample files, a difference summary, bulk selection buttons and touch-friendly editing, and surrounded it with documentation. The original licence text is available at /LICENSE.txt.
