How to use Convert BGR to JPEG
- 1. Paste the BGR values. Enter a flat list of numbers, three per pixel with blue first followed by green and red, in row-by-row order matching the image you want to rebuild.
- 2. Set the image dimensions and quality. Enter Width (px), Height (px, 0 = auto) to compute rows automatically, and JPEG quality (%) to control how the rebuilt image is compressed.
- 3. Download the rebuilt image. The tool reads blue first for each pixel, reorders it correctly and encodes the result as image.jpg. Download it to confirm your BGR data forms the intended picture.
When to use Convert BGR to JPEG
Convert BGR to JPEG rebuilds a viewable image from pixel data ordered blue-green-red, the layout OpenCV and similar libraries use internally. It gives you a way to visually check BGR-formatted pixel arrays without writing a separate script just to view them.
- Visualizing an OpenCV array without writing extra code. You have a numpy or similar array of pixel values straight out of an OpenCV read, already in BGR order. Pasting those values here renders the image directly without a channel-swap script.
- Verifying a computer vision preprocessing step. A pipeline stage transforms pixel data before feeding it into a model, and you want to confirm the image still looks correct in BGR order at that stage. Rebuilding it here gives an instant visual check.
- Debugging a channel-order assumption in your code. You suspect a bug where your code treats RGB data as if it were BGR or vice versa. Rebuilding the same values under a BGR interpretation shows whether that assumption explains the wrong colors.
- Reconstructing an image from a vision library's memory buffer. You dumped a raw pixel buffer from a vision library that stores data in BGR order and want to see what image it represents. Pasting the values here reconstructs it visually.

About the Convert BGR to JPEG tool
Convert BGR to JPEG runs as plain JavaScript in your browser tab, with no server behind it. Rebuild a JPEG from a raw BGR pixel array. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's JPG Tools section, 145 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with 3 settings, including Width (px), Height (px, 0 = auto) and JPEG quality (%), and the result refreshes the moment you change one. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Is Convert BGR to JPEG free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
How do I save the output?
Click the Download button once the result is ready. The file is built in your browser's memory and handed straight to your downloads folder, without passing through a server.
