7 SubtitleTools Alternatives Compared: Pricing, API, Batch & Repair (2026)
SubtitleTools is a handy free converter. But if you are bumping into its limits — one file at a time, basic repair utilities, and an API whose price you have to ask for — here is what the alternatives actually offer.
How we compared
Free converter lists usually rank by feature-count bingo. We compared on the four things that decide whether a tool survives real subtitle work:
- Published pricing — can you see what things cost without filling in a form?
- API access — can conversion be wired into a pipeline, and is the price on the page?
- Batch conversion — one file per upload, or a queue?
- Repair tools — does anything fix broken timing, encoding, or junk formatting?
A sourcing note up front: several vendor sites restrict automated access. Figures marked with an asterisk come from public pricing pages and third-party reviews aggregated at collection time (September 2026), so treat approximations as approximations and verify against the vendor's own page before you buy.

The 7 alternatives, one by one
1. SRTKit — the full toolkit in one place
Free single-file conversion with no sign-up, a batch queue for whole folders, a REST API with published per-use pricing, and a repair toolkit for the ways subtitles actually break: sync drift, garbled encoding, SDH tagging, ragged line breaks. Exports are clean — no forced watermark, ever. The pitch is not the lowest price; it is the combination, which nothing else in this list ships in one place. Official site (visited September 2026).
2. GoTranscript Converter — the free workhorse
A completely free converter with no login and no stated limits, covering a wide format list including SCC, STL, TTML and DFXP (Timed Text). It exists largely as a funnel to the company's human transcription service. No repair tools, no API. Official site (visited September 2026).
3. VEED — the video suite
A full online video editor with subtitle features attached. The free tier requires an account and exports carry a watermark; free usage is capped by two separate limits — roughly a 10-minute cap per export and about 10 minutes of AI subtitles per month. Paid plans start around $12/month billed yearly. No converter API, no repair toolkit. Official site (visited September 2026).
4. HappyScribe — the transcription SaaS
Transcription and subtitles platform. Free access is a 10-minute trial with an account required. Reported entry prices range widely — roughly €6 to $17 per month depending on the source — so treat any single figure you see as unverified until you check the current pricing page. No repair toolkit; API availability for conversion is not documented. Official site (visited September 2026).
5. TurboScribe — transcription first
AI transcription with subtitle export. The free tier gives 90 minutes a day (three 30-minute files) with an account; the paid plan — named "Unlimited" by the vendor — costs $10/month billed yearly. No subtitle repair tools and no documented conversion API. One caution for your own research: older comparisons sometimes attach a per-file price to TurboScribe that traces back to a different product entirely — always verify against the vendor's own pricing page. Official site (visited September 2026).
6. Sonix — the developer option
AI transcription platform with the strongest developer story in this list: a REST API plus Zapier and webhooks. 30-minute free trial without a credit card; paid plans from $25/month (Core, billed annually). No repair toolkit. Official site (visited September 2026).
7. Rev — the human-powered premium route
Best known for human transcription at $1.99/minute, with automated and human subtitle products above that. The free tier could not be verified at collection time. No documented conversion API, no repair tools. Official site (visited September 2026).
Where SubtitleTools itself still wins
Credit where due. SubtitleTools' converter is genuinely free with no ads and no tracking cookies. The format list is broad, and it includes OCR paths (SUP / Sub-Idx) that most rivals skip entirely. Its repair utilities are real, if scattered — a shifter here, a cleaner there, without a connected workflow. And its API exists, but sits behind a Premium tier with no published price: you have to ask. That last point is the one worth pausing on, because it is the difference between a tool and a quote. Official site (visited September 2026).
What to check before you pick
Is the API price published?
If learning the price requires a form, budget for surprises. Published per-use pricing means you can do the math before you commit.
Does anything repair, not just convert?
Conversion swaps containers. Overlapping cues, encoding mismatches, SDH junk and broken line wraps survive conversion untouched.
Can it do many files at once?
One-at-a-time uploads are fine for a single episode. For a season, a queue is the difference between minutes and an afternoon.
Why SRTKit is on this list
Not because it is the cheapest — because it is the only entry here that ships the full combination in one subscription: a batch queue for folders, a REST API with published per-use pricing, and a connected repair toolkit covering sync, encoding, SDH cleanup and line wrapping. Every export is clean — no forced watermark, ever. Start free on the homepage, or read the broadcast subtitle formats guide if you are untangling SCC, STL, DFXP or TTML deliveries.
