How to use Create a Custom PNG
- 1. Choose your canvas size. There is no file to upload here. Start by setting Width (px) and Height (px) to the exact dimensions you need for the generated placeholder.
- 2. Set the background and label. Pick a Background color, then optionally type into Label to stamp text like the dimensions onto the image, and set Label color so it stays readable against the background.
- 3. Download the generated PNG. Save the resulting custom.png, a labeled placeholder such as an 800 by 600 gray box marked with its own dimensions, ready for use in a mockup or layout.
When to use Create a Custom PNG
Create a Custom PNG generates a PNG with your own size, background color and optional label, entirely from settings rather than an uploaded image. Create a Custom PNG is for the everyday need of a quick placeholder graphic while a design or layout is still being built.
- Filling a wireframe with placeholder images. A designer building a website wireframe needs generic gray boxes at exact pixel dimensions to stand in for photos that have not been shot yet.
- Testing a responsive layout at specific sizes. A developer checking how a grid handles different image dimensions generates several custom placeholders at exact widths and heights to test the layout.
- Labeling test assets by dimension. A QA engineer building test fixtures generates PNGs labeled with their own size, such as 800 by 600, to make it obvious which asset is which during testing.
Examples

Input
800×600, gray, label “800×600”

About the Create a Custom PNG tool
Create a Custom PNG is a free online tool that works entirely inside your web browser. Generate a PNG with your own size, background color and optional label. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 108 PNG utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 5 settings, including Width (px), Height (px), Background color and Label (optional), 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.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
