Converting SRT captions to YML keeps the timings intact while matching the syntax your player, platform or browser actually parses. YML (YAML document) earns its place here: readable nested configuration that tools parse directly. SRT is the simplest subtitle format: a number, a timestamp range and the caption text. Every media player and video platform accepts it.
SRT is the simplest subtitle format: a number, a timestamp range and the caption text. Every media player and video platform accepts it.
Timings and caption text transfer exactly; only the syntax around them changes. Styling and positioning cues survive when YML supports them and are dropped when it does not, and timestamp precision is preserved to the millisecond.
What you gain with YML: Readable nested configuration that tools parse directly.
Drop your SRT file above and Morphio decodes it locally, then re-encodes it as YML using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle. See exactly how in-browser conversion works.
Open the SRT to YML page, drop your document on the drop zone and press convert. Morphio runs local parsers such as pdf.js that execute in your own tab, so the SRT data never leaves your device and no server ever receives a copy.
Text and structure are read locally, so nothing is retyped, re-uploaded, or sent to an OCR service. Converting SRT to YML only rewrites the container and encoding you asked for — the source file on your disk is never modified.
Yes. The free plan covers 10 conversions a day with files up to 200 MB and adds no watermark or sign-up. Morphio Pro ($5/month, or $29 once for lifetime access) removes the daily cap and raises the per-file limit to 5 GB.
No. The content is remapped from SRT into YML structurally, so nothing is re-compressed. Only features YML has no way to express are left behind.
Yes — drop the whole batch in and each file is processed in turn on your own machine. The practical limit is your device's memory and patience, not a server quota, because nothing is queued anywhere else.
No. The conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can disconnect from the internet after the page loads and it still works.
