About Tubelexity
Tubelexity provides free browser-based tools for YouTubers to edit, compress, convert and prepare videos, audio, thumbnails and subtitles without watermarks or AI credits. Each tool is focused on a practical creator task.
Local processing when supported
Where the browser can handle it, your file never leaves your device.
No AI keys or credits
Tubelexity relies on browser APIs — FFmpeg.wasm, Canvas, Web Audio — not paid AI services.
No watermark
Exported files never carry a Tubelexity badge or watermark.
Focused, not bloated
You won't find a full timeline editor here. Each tool is scoped to a single task.
What Tubelexity is not
- It is not affiliated with YouTube or Google.
- It does not download or scrape videos from YouTube.
- It does not generate content with AI.
- It does not require an account or store your files on a server.
How media processing works
Files are processed locally in the browser when supported by the selected tool. Image and preview workflows use native media and Canvas APIs. Advanced video and audio exports use FFmpeg.wasm, whose media engine is downloaded on first use. Tubelexity does not send user media, subtitle text or filenames to a processing backend.
Browser codec support, device memory and processing speed vary. Each tool page lists its supported inputs and real limitations instead of claiming universal compatibility.
