About Subtitleiy
"We built Subtitleiy because working with subtitle files shouldn't require paid software, a sign-up form, or a technical background. Every tool should just work — instantly, for free."
What We Do
Subtitleiy is a free online toolkit for anyone who works with subtitle files. Whether you need to fix timing, convert formats, clean up text, or add Chinese pinyin — we have a tool for it, and it runs instantly in your browser.
Instant Results
Upload your file, pick your settings, download the result. No waiting, no queues.
Privacy First
All client-side tools process files entirely in your browser. Your subtitles never leave your device.
Batch Processing
Upload up to 50 files at once and download all results as a single ZIP.
Works Everywhere
Output files work with VLC, Plex, Kodi, MPC-HC, and virtually every player and platform.
Our Tools
Subtitleiy includes 12 free tools covering the most common subtitle tasks:
- Converters — SRT, WebVTT, Plain Text, PDF, UTF-8, Chinese Pinyin
- Syncing — Global sync shifter and partial (multi-range) sync shifter
- Fixing — SRT Cleaner (SDH removal, ads, tags) and Subtitle Merger
- Styling — Change subtitle color and position
Why Free?
We believe access to basic media tools shouldn't depend on your budget. Most tools run entirely in your browser — they cost nothing to operate — so we can offer them completely free with no limits. Server-side tools (PDF, UTF-8, Pinyin) are supported by non-intrusive ads.
