UYVY to RAS Converter
Processing entirely on your device — large files may take a moment.
Convert to RAS for legacy UNIX image archives. If your files are still in UYVY format, this page is the shortcut: UYVY is packed 4:2:2 Y'CbCr — two pixels per four bytes, the native format of broadcast video capture cards and frame buffers.
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 UYVY format
The UYVY 4:2:2 (raw) coder of the ImageMagick set — the video-hardware 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.

Converting makes sense where the strengths of RAS meet what UYVY 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 UYVY to RAS 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 RAS?
No — RAS 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.
Can I convert several UYVY files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
