One Video That Works Everywhere You Post

Captions That Survive Every Platform

TikTok, Instagram and Snapchat cannot load separate subtitle files, so subtitles made that way simply never appear. Eliro puts your captions inside the video itself, so one download plays exactly the same way in every app and on every phone.

Your Own Style, Not the App's Default

TikTok gives you a handful of fonts. Instagram does not let you pick one at all. That is why so much of the feed looks the same. In Eliro you choose the font, color, size and animation yourself, then save that look so every video you post is recognisably yours.

Everyone Can Follow What You Say

Some of your viewers cannot hear your audio at all, and many more choose to watch without sound. Subtitles let every one of them follow what you are saying. Burn them into the video and they show for everyone, on every app, with nothing to switch on.

Hardcode Subtitles FAQs

What is the difference between soft and hard subtitles?
Soft subtitles are a separate file the player can switch on or off, so they do not always show. Hard subtitles are part of the video itself. Eliro burns yours in, so they show every time, everywhere.
What are hardcoded subtitles?
They are subtitles that become part of the video itself. Because the words are inside the picture, they show on any device and in any app, without the platform needing to do anything.
What is the difference between hardcoded and closed captions?
Closed captions sit outside the video in a separate file the player has to read, and each platform styles them its own way. Hardcoded subtitles are drawn into the picture, so the look you designed is the look everyone sees.
Does burning in subtitles lower the video quality?
No. Your subtitles are rendered at your video's own resolution, so the text comes out sharp and the footage looks exactly as good as the file you uploaded.
Do hardcoded subtitles work on TikTok, Reels and Shorts?
Yes, and this is where they matter most. Those feeds will not read a separate subtitle file, so burning the words in is what guarantees every viewer sees them. You can publish straight to TikTok, Instagram, YouTube and Facebook from Eliro.
Can viewers turn hardcoded subtitles off?
No, and for social video that is the whole point. The words are always on screen, so a muted autoplay in someone's feed still lands every line you said.
Do I need to prepare a subtitle file first?
Not at all. Upload the video and the AI writes and times every word from your audio, so the only thing left for you is choosing how it looks.
Do exports come with a watermark?
No watermark, on any plan. Free accounts export watermark-free videos at full quality, with your subtitles burned in.
What if the AI gets a word wrong?
Just click the word and retype it before you export. Subtitles edit like text, so your timing stays exactly where it is while you fix the spelling.
What video files can I upload?
We support all the popular formats like MP4, MOV, WEBM and M4V. Drag your file in and the subtitles start writing on their own.
Which languages can it subtitle?
More than 99, including English, Spanish, Hindi, Japanese, Arabic, Portuguese and Mandarin. Your subtitles come back in the language you recorded in.
Is there a free plan?
Yes, and it comes with generous free usage, unlimited exports and no watermark. Paid plans give you more credits, and they work across every tool in Eliro.
