How to use Convert Hex Codes to an Image
- 1. Paste the hex color codes. Paste a list of #rrggbb hex codes into the input pane, separated by spaces or line breaks, in the order you want them laid out left to right, top to bottom.
- 2. Set the Width (pixels). Enter how many colors should form each row before wrapping to the next line, which determines the resulting image's width and shape.
- 3. Download the built PNG. Save the generated image once the preview shows the color strip or grid matching your list, with each hex code rendered as one solid pixel.
When to use Convert Hex Codes to an Image
Convert Hex Codes to an Image builds a PNG from a plain list of hex color codes, one pixel per code. It is for turning color data you already have as text into an actual visual swatch or tiny pixel-art image.
- Visualizing a color palette list. A design system's color tokens are listed as hex codes in documentation, and turning them into a strip of pixels gives an at-a-glance visual reference of the whole palette.
- Reconstructing pixel art from saved data. A tiny sprite's colors were saved as a text list of hex codes for version control, and rebuilding the actual image confirms the data still produces the right picture.
- Testing color output from a script. A script that generates hex codes algorithmically, such as a gradient or random palette generator, can be visually checked by feeding its output straight into this tool.
Examples

About the Convert Hex Codes to an Image tool
Convert Hex Codes to an Image runs as plain JavaScript in your browser tab, with no server behind it. Build a PNG from a list of hex color codes, one pixel each. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Image Tools section, 200 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 the Width (pixels) setting, and the result refreshes the moment you change it. 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 Hex Codes to an Image 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.
