Create an Empty WebP
Create a blank WebP of any size: fully transparent or filled white. Runs entirely in your browser, so your data never leaves your device.
Output
The result appears here as you type.
How to use Create an Empty WebP
- 1. Choose the canvas size. Enter Width (px) and Height (px) for the blank image you want to generate. There is nothing to upload here, since this tool builds a fresh file from scratch.
- 2. Choose transparent or white. Toggle Transparent (otherwise white) to decide the fill. Leave it on for a fully see-through canvas, or turn it off for a solid white background instead.
- 3. Download the blank WebP. Click generate and download the resulting file, a plain canvas at the exact size you specified, ready to build on in any image editor.
When to use Create an Empty WebP
Create an Empty WebP generates a blank canvas at any size, either fully transparent or filled white, with nothing else on it. It is for the moment a project needs a starting placeholder rather than an actual photo.
- Seeding a layout with a placeholder. A web layout is being built before the real images arrive, and a blank transparent WebP of the correct dimensions holds the spot without breaking the page's structure.
- Testing an upload pipeline. A developer testing an image upload feature needs a minimal valid file at a specific size, and a blank generated WebP works without needing a real photo on hand.
- Starting a new canvas in an editor. Someone wants to paint or composite a new graphic from scratch and needs a plain background of an exact pixel size to open as the starting layer.

About the Create an Empty WebP tool
Create an Empty WebP does its work locally, right in the browser. Create a blank WebP of any size: fully transparent or filled white. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the WebP Tools collection on EditSafely, a set of 57 small, focused WebP utilities that share the same instant, private workspace.
You can shape the output with 3 settings, including Width (px), Height (px) and Transparent (otherwise white), 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.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
