Convert JPEG to RAW

Understanding jpeg and raw file formats

JPEG (Joint Photographic Experts Group) is a widely used compressed image format known for its small file size and lossy compression. It is ideal for sharing and storing photos but sacrifices some image quality and editing flexibility.

RAW files are unprocessed image data captured directly from a camera's sensor. They retain all the original information, allowing for extensive post-processing and higher image quality. RAW files are preferred by professional photographers for their flexibility and detail preservation.

Why convert jpeg to raw?

Converting JPEG to RAW is uncommon and generally not recommended because JPEG files have already undergone compression and data loss. However, some users may wish to convert JPEGs to RAW for compatibility with certain editing workflows or software that only accepts RAW files.

How to convert jpeg to raw

While you cannot truly restore lost data from a JPEG, you can convert it to a RAW-like format (such as DNG) for editing purposes. Here are the steps using the best available software:

• Adobe Photoshop: Open your JPEG file, then use File → Save As and select DNG (Digital Negative) if available. Note that this does not restore original RAW data but creates a RAW-compatible file.
• Adobe DNG Converter: This tool can convert JPEGs to DNG format, making them compatible with RAW workflows. Simply add your JPEG files and select the output folder.
• RawTherapee: Open your JPEG, edit as needed, and export as a TIFF or DNG file for further RAW-like editing.

Best software for jpeg to raw conversion

The most reliable software for this process is Adobe DNG Converter, as it creates a DNG file that can be used in most RAW editing applications. However, remember that the conversion does not recover the original sensor data lost during JPEG compression.

Important considerations

• Converting JPEG to RAW does not restore lost image data.
• The resulting file is only RAW-compatible, not a true RAW file.
• For best results, always shoot and save in RAW format from your camera.
