How to use Convert JPG to BGR
- 1. Add the JPG to dump. Drop in the photo whose pixel data you need in BGR order, the byte layout used by OpenCV and several other computer vision and imaging libraries.
- 2. Set the value formatting. Type a Value separator to place between the blue, green and red numbers, and toggle One pixel per line to control how pixels are arranged in the output text.
- 3. Copy the BGR values. The tool outputs blue first, then green and red, for every pixel in order. Copy the result into code or a library that specifically expects the BGR channel order.
When to use Convert JPG to BGR
Convert JPG to BGR dumps every pixel's blue, green and red values in that order, matching the layout OpenCV and some other computer vision libraries use internally instead of RGB. It saves a manual channel-swap step when preparing test data for BGR-based code.
- Preparing test input for an OpenCV-based script. You are writing a computer vision script and OpenCV loads images internally in BGR order rather than RGB. Extracting a photo's pixels in BGR gives you data that matches exactly what OpenCV would produce.
- Debugging a color-swapped image in a vision pipeline. An image processed through an OpenCV pipeline shows red and blue swapped compared to the original. Extracting the raw BGR values helps confirm whether a channel-order mixup is the cause.
- Writing unit tests for a BGR-based image function. Your test suite needs realistic pixel arrays in BGR order to validate a function that assumes that channel layout. Extracting them from a real photo beats hand-writing fake arrays.
- Documenting a format that stores colors as BGR. You are writing documentation or reverse engineering a file format known to store pixels in BGR order, such as some Windows bitmap variants. Extracting sample data gives you a concrete reference.

About the Convert JPG to BGR tool
Convert JPG to BGR is a free online tool that works entirely inside your web browser. Dump the raw BGR pixel array of a JPG. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 145 JPG utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 2 settings, including Value separator and One pixel per line, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
