Add your SUB file
Drop one or more .sub files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
SUB to TXT
Converting a .sub file to .txt extracts the document's content from its office package into a portable form. Free, private, and validated — the file never leaves your browser.

Converting a .sub file to .txt extracts the document's content from its office package into a portable form. A .sub file in the MicroDVD convention is a frame-based subtitle list: every line reads {startFrame}{endFrame}text, with a pipe character separating the lines inside one cue. Because the timing is expressed in frames rather than milliseconds, a MicroDVD file only means anything alongside the frame rate of the video it was timed to.
A .txt file is plain text: nothing but a sequence of characters and line breaks, with no fonts, styles, or embedded objects. It is the lowest common denominator of documents — every computing device of the past several decades can open one. For this route the practical draw is opens everywhere, indefinitely — no format rot possible and the smallest possible representation of textual content — balanced against no formatting, images, or tables of any kind, which is worth knowing before you commit a large batch.
Why convert SUB to TXT?
The practical trigger for this conversion is usually a mismatch: with .sub, meaningless without the correct frame rate; the wrong value drifts the whole file. Switching to .txt buys you opens everywhere, indefinitely — no format rot possible, which is why it is the better fit for notes, to-do lists, and drafts that must outlive any particular app. Because the conversion runs locally, trying it costs nothing but a few seconds of compute on your own machine.
SUB vs TXT at a glance
| Aspect | MicroDVD subtitles (.sub) | Plain text (.txt) |
|---|---|---|
| Format type | Text-based — characters and structure, so there is no visual quality loss | Text-based — characters and structure, so there is no visual quality loss |
| How it stores data | each cue is one line: {startFrame}{endFrame} followed by the text, with | separating multiple display lines | no internal structure at all — bytes plus an assumed text encoding are the entire format |
| Strongest at | playing back subtitles that were timed against a specific video rip | notes, to-do lists, and drafts that must outlive any particular app |
| Weak spot | meaningless without the correct frame rate; the wrong value drifts the whole file | no formatting, images, or tables of any kind |
Pick TXT as the output
Select .txt in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if TXT is selectable, the route is real and validated.
Convert on your device
Press Convert. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid TXT file. Outputs keep the original filename with the .txt extension.
SUB to TXT questions, answered
Will converting SUB to TXT lose quality?
There is no visual quality to lose — sub is text-oriented and txt is text-oriented, so the question is structural fidelity. Text, ordering, and basic structure are preserved; complex layout, embedded objects, and styling beyond the target's model are simplified.
Is it private to convert SUB files here?
Yes — the .sub file is processed inside your browser tab and never uploaded. The package is unzipped in memory and its XML content parsed locally; nothing is uploaded. Close the tab and the file is gone from memory.
Where will the TXT file work?
Notepad, TextEdit, every code editor, every browser, and every phone open .txt without hesitation. It is the one document format with genuinely universal support across operating systems and decades.
Will the TXT file be bigger or smaller than my SUB?
It depends on the content: no internal structure at all — bytes plus an assumed text encoding are the entire format. Convert one representative file first and compare before batch-processing a large set.
What happens to the metadata in my SUB file?
In .sub, there is no metadata section; the only header-like content is the frame-rate declaration, which is read on input and written on output. Re-encoding through the browser pipeline does not carry embedded metadata into the output, which doubles as a privacy scrub — check the exported file if you specifically need tags preserved.
