What a plain colour file is for
Faster than opening an editor
Needing a flat colour rectangle is common and opening a design tool to make one is absurd. Pick the hex, set the size, download. Nothing is uploaded because there is nothing to upload.
Set the size that matters
The default is 1200 by 630, the standard social preview size, because that is the most common reason to want one. Leave the height at zero for a square instead.
Placeholders that do not lie
A flat colour block makes a better layout placeholder than a stock photo — it fills the space without suggesting content that will not be there. Use your brand colour and the mock reads as deliberate.
PNG, and exactly the colour you asked for
The output is a lossless PNG, so the hex you enter is the hex in the file. A JPG of a flat colour is a slightly different colour with compression noise on it, which matters when someone samples it later.
For a transparent file instead
This always produces an opaque fill. If what you want is a blank transparent canvas, that is the empty PNG generator.
Using flat colour files
Better placeholders than stock
A flat block fills the space without promising content that will not exist. Use the brand colour and the mock reads as intentional.
Keep it PNG
A JPG of a flat colour is a slightly different colour with noise on it. That matters as soon as someone samples the file.
1200×630 is the safe default
It is the standard social preview size, which is the most common reason to need one of these at all.

Describe the edit in your own words
