Convert YUV to JPEG

Understanding YUV and JPEG file formats

YUV is a color encoding system typically used in video processing and image compression. It separates image luminance (Y) from chrominance (U and V), making it efficient for bandwidth and storage, especially in video applications. YUV files often contain raw, uncompressed image data and are not directly viewable in standard image viewers.

JPEG (Joint Photographic Experts Group) is a widely used compressed image format. It uses lossy compression to reduce file size while maintaining acceptable image quality, making it ideal for photographs and web images. JPEG files are universally supported by image viewers and editors.

Why convert YUV to JPEG?

Converting YUV to JPEG allows you to easily view, share, and edit raw video frames or images captured in YUV format. JPEG’s compression and compatibility make it suitable for archiving and distribution.

Best software for YUV to JPEG conversion

FFmpeg is the most recommended tool for converting YUV files to JPEG. It is a powerful, open-source multimedia framework that supports a wide range of formats and conversions.

How to convert YUV to JPEG using FFmpeg

1. Download and install FFmpeg for your operating system.
2. Open a command prompt or terminal window.
3. Use the following command to convert your YUV file to JPEG:
   ffmpeg -f rawvideo -pix_fmt yuv420p -s WIDTHxHEIGHT -i input.yuv output.jpg
   Replace WIDTH and HEIGHT with your image dimensions, and input.yuv with your file name.
4. If your YUV file contains multiple frames, FFmpeg can output a sequence of JPEG images:
   ffmpeg -f rawvideo -pix_fmt yuv420p -s WIDTHxHEIGHT -i input.yuv output_%03d.jpg

Alternative converters

• XnConvert: A user-friendly batch image converter that supports YUV to JPEG conversion with a graphical interface.
• IrfanView: With the appropriate plugins, IrfanView can open YUV files and save them as JPEG via File → Save As.

Tips for successful conversion

• Ensure you know the correct pixel format and resolution of your YUV file.
• JPEG is a lossy format; some quality loss is expected after conversion.
• For batch conversions, FFmpeg’s command-line options are highly efficient.
