GRAYA to UYVY Converter
Processing entirely on your device — large files may take a moment.
Grayscale + Alpha (raw) and UYVY 4:2:2 (raw) exist for different jobs: GRAYA is raw 8-bit greyscale-plus-alpha pixels with no container — the lingua franca of shader pipelines and scientific imaging that just want the bytes. Convert stills to UYVY for video hardware test patterns.
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.

About the GRAYA format
The Grayscale + Alpha (raw) coder of the ImageMagick set — the raw-pixels format is written natively by the magick.wasm engine, entirely in your browser.
Obscure coder formats like this are exactly what template-driven converters list and never actually convert — here it really works.
+Strengths
- ✓Written natively by ImageMagick
- ✓Runs entirely in your browser
- ✓Free, private, no watermarks
!Limitations
- −Niche format — few modern readers
- −Feature subset varies by coder
- −Keep the original for re-editing

Frequently asked questions
Is this GRAYA to UYVY 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 converting GRAYA to UYVY reduce quality?
UYVY uses lossy compression, so a small amount of recompression is unavoidable. The quality slider lets you choose between maximum fidelity and smallest file size — the default is visually indistinguishable for photos.
Will transparent areas survive the conversion to UYVY?
Transparency is kept whenever UYVY 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.
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 GRAYA files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
