Frequently Asked Questions
How does color detection work?
Click one browser-rendered pixel to choose the target RGB value. Vizua replaces every decoded pixel whose Euclidean RGB distance from that target is within the 0–100 tolerance. This is a global threshold, not flood fill, subject detection, or a selection limited to connected background regions.
What if my background has multiple shades?
A higher tolerance includes a wider RGB range, but it can also replace foreground pixels with similar colors. Start at a low value, inspect the entire output and edges, and use a mask-based editor when one global target is not selective enough.
Does it work with gradients?
A gradient may exceed the distance around the one selected color. Raising tolerance can include more of it but also more unrelated pixels; the tool does not accept multiple simultaneous target samples or create a semantic background mask.
What you can do with Change Background Color by RGB Distance
Replace pixels near one selected RGB target with another color in your browser. Adjust global tolerance, inspect edges, and export.
Change Background Color by RGB Distance is designed for quick, repeatable work in a modern browser. The controls on this page let you prepare the result without installing software or creating an account.
How to use Change Background Color by RGB Distance
- Select or drop the file you want to process, or enter the information requested by the tool.
- Review the available settings before processing, especially format, dimensions, quality, color, or other details that affect the output.
- Inspect the result, download the new file, and keep the original unchanged in case you need another version.
Private by design
Your files never leave your device. All processing happens locally in your browser.
Tips for better results
- Start with the cleanest source available; a small, blurry, or heavily compressed file contains less detail to preserve.
- Check dimensions and format before downloading so the result matches the site, app, printer, or platform where you will use it.
- For large files, close unnecessary tabs and test one representative file before processing a full batch.
- Open the downloaded result once before sharing it or replacing an original.
Where Change Background Color by RGB Distance fits in a workflow
Use Change Background Color by RGB Distance for one-off adjustments or as a preparation step before publishing, sharing, archiving, or continuing the edit in another application. When batch processing is available, validate the settings on a small sample first and then apply them to the remaining files.
