GRAY to UYVY Converter
Processing entirely on your device — large files may take a moment.
Raw Grayscale Image and UYVY 4:2:2 (raw) exist for different jobs: GRAY is the single-channel spelling of raw grayscale dumps — the same unformatted luminance bytes the GRAYA variant adds alpha to. Convert stills to UYVY for video hardware test patterns.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the GRAY 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

Why convert GRAY to UYVY?
Converting makes sense where the strengths of UYVY meet what GRAY cannot give you. Written natively by ImageMagick Meanwhile Niche format — few modern readers One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this GRAY 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 GRAY 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 GRAY files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
