UYVY to OTB Converter
Processing entirely on your device — large files may take a moment.
UYVY 4:2:2 (raw) and Nokia OTA Bitmap exist for different jobs: UYVY is packed 4:2:2 Y'CbCr — two pixels per four bytes, the native format of broadcast video capture cards and frame buffers. Convert images to 1-bit OTB for retro phone displays.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

Frequently asked questions
Is this UYVY to OTB converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting UYVY to OTB?
No — OTB is a lossless format, so every pixel of the converted image matches your original UYVY file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your UYVY files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to OTB?
Transparency is kept whenever OTB actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
