How to use Convert PNG to RGBA Values
- 1. Upload your PNG. Add the image you want dumped as raw numbers, such as a small 2 by 1 pixel PNG with a red pixel and a half-transparent blue pixel.
- 2. Choose your separator and layout. Set Value separator to control what character sits between numbers, and turn on One pixel per line to put each pixel's four values on its own line instead of one long string.
- 3. Copy the RGBA values. Copy the resulting output, such as 255 0 0 255 followed by 0 0 255 128, and paste it into a script, spreadsheet or debugging note that needs raw pixel data.
When to use Convert PNG to RGBA Values
Convert PNG to RGBA Values dumps every pixel of a PNG as raw Red, Green, Blue and Alpha numbers, exposing the transparency channel that a plain RGB dump would drop. Convert PNG to RGBA Values matters whenever alpha transparency itself is part of what you need to inspect or process.
- Debugging a transparency mask. A developer troubleshooting a UI overlay that renders with the wrong opacity dumps its PNG to RGBA values to confirm the alpha channel holds the expected numbers.
- Verifying a compositing pipeline. Someone building an image compositing tool checks a test PNG's exact RGBA values line by line to confirm blending math produces the expected output pixel.
- Feeding pixel data with alpha into a script. A developer writing a script that needs both color and transparency per pixel extracts RGBA values with one pixel per line for easy parsing.
