ConvertUno converts and compresses video, audio, images and PDFs entirely on your device โ€” files are never uploaded, because there is no server that could receive them.

How it works: conversions run on WebCodecs, the browser's hardware-accelerated codec API. Videos whose streams already fit the target container are repackaged losslessly in a couple of seconds regardless of size, and the UI says when that happened versus a real re-encode. Formats browsers can't read (AVI, WMV, FLV, VOB, MPGโ€ฆ) fall back to a bundled software engine (~31 MB) that loads only the first time it's needed.

Verified converters: no format pair gets a page unless an automated real-browser test has pushed an actual file through that exact page and checked the output's file signature. If a page exists, the conversion works: https://convertuno.com/blog/how-we-verify-every-converter

Tools:

  • Video & audio conversion โ€” MP4, WebM, MKV, MOV, GIF, MP3, WAV, M4A, OGG, AAC, FLAC
  • Video compression with target size ("fit to 10 MB")
  • Image conversion & compression โ€” HEIC, PNG, JPG, WebP and more
  • PDF: merge, split, rotate, delete pages, compress, extract images, PDF to image
  • Archive extraction

Practical details: free, no accounts, no watermarks, no size caps. Works offline after your first visit. Available in 11 languages. Batch conversion supported.
