Frequently asked questions (FAQs) about this topic

Can I add subtitles to iPhone videos for free?

Yes, many iPhone subtitle apps let you generate and edit captions without paying upfront. Free plans often include basic transcription, manual timing and standard exports. Some may limit advanced styling, longer videos or watermark-free output.

Do free subtitle apps put watermarks on exports?

Some do, especially on free tiers or trial versions. Others allow watermark-free exports but restrict features such as longer projects or premium fonts. Always check the export settings before you finish a video.

How accurate is automatic subtitle generation on iPhone?

Accuracy depends on audio clarity, accents, background noise and the language being transcribed. Clean speech with minimal noise usually produces the best results. Manual review is still important to fix names, slang and punctuation.

What subtitle formats work best for social media videos?

Burned-in subtitles are the safest choice for social platforms because they stay visible everywhere. If you need editing flexibility, look for tools that also export subtitle files such as SRT. That makes it easier to reuse captions across platforms and projects.
