Convert PNG to RAW
About PNG
Portable Network Graphics (PNG) is a raster graphics format that supports lossless data compression, meaning no quality is lost when the file is compressed. Its most notable feature is its support for transparency (the alpha channel), which allows images to have transparent backgrounds. This makes PNG a favorite for web graphics, logos, and icons.
About RAW
A RAW image file is often called a 'digital negative'. It contains the unprocessed, untouched data directly from a digital camera's sensor. Unlike formats like JPEG, which are processed and compressed by the camera, a RAW file gives the photographer complete control over editing aspects like white balance, exposure, and color. This provides the highest possible quality and editing flexibility.

Frequently Asked Questions
Is PNG better than JPEG?
It depends on the use case. For photographs, JPEG provides smaller file sizes with minimal perceptible quality loss. For graphics with sharp lines, text, or transparency needs, PNG is superior as it is lossless and supports an alpha channel.
Why are PNG files larger than JPEGs?
PNG files are larger because they use lossless compression. They retain all the original image data, whereas JPEG uses lossy compression to discard data and reduce file size. This makes PNGs higher quality but also larger.
Can I open a RAW file in any program?
No, RAW files require special software. Each camera manufacturer has its own proprietary RAW format (e.g., .CR2 for Canon, .NEF for Nikon), so you need a program like Adobe Lightroom, Photoshop, or manufacturer-specific software that can read your camera's specific file type.
Why not just shoot in JPEG?
Shooting in JPEG is faster and produces ready-to-use files. However, shooting in RAW provides a much higher quality source file with more latitude for making corrections and creative adjustments during post-processing. For professional work or serious hobbyists, RAW is the preferred format.
