Free voice over & subtitling tools

Practical, no-sign-up tools we built from real localisation projects — work out a usage fee, estimate script time, check subtitle reading speed or convert subtitle files. Free to use, and free to link to.

Free tools — common questions

Are these tools really free?

Yes — every tool is free and needs no sign-up or account. We built them from our own day-to-day voice over, subtitling and localisation work, and share them because they save our clients (and us) time.

Do the tools give me an exact price?

The usage-fee calculator shows you what genuinely drives a voice over fee — the recording (studio) fee plus a usage licence set by media, territory and term — and hands your choices to us for an exact, itemised quote. We don't show a fabricated instant figure, because a real price depends on your script length, talent and how the audio is used, and we'd rather be accurate than approximate.

Is my data or my files kept?

The subtitle converter runs entirely in your browser — your files are never uploaded to a server. The other tools only use what you type to give you a result on the page.

Do you also provide the services these tools relate to?

Yes. We're a voice over, subtitling, translation and transcription agency with native talent in 100+ languages, recorded in our own Central-London studios. If the tools raise a question, send us your brief and we'll help — usually within a few hours.

Can I link to these tools from my own site?

Please do — you're welcome to link to any of them. They're meant to be useful references for anyone producing localised audio or video.

Which subtitle formats does the converter handle?

The subtitle converter works with the common formats — SRT and VTT among them — and runs entirely in your browser, so you can convert between them without uploading anything or installing software.

What reading-speed limits does the subtitle checker use?

The reading-speed checker measures characters per second (CPS) against presets for platforms like Netflix, broadcast and social, and lets you set your own limit — then flags the lines that run too fast and lets you export a clean report.

How accurate is the script-time calculator?

It's a reliable estimate for budgeting and session planning, based on a typical delivery pace. The exact runtime always depends on the voice and the read — a documentary is slower than a fast retail ad — so treat it as a close guide rather than a to-the-second figure.

Can the usage-fee calculator tell me the final price?

It shows you what drives a voice over fee — the recording (studio) fee plus a usage licence set by media, territory and term — and hands your choices to us for an exact, itemised quote. We don't show a fabricated instant number because a real price depends on your script and how the audio is used, and we'd rather be accurate than approximate.
