How to use Create a Custom JPG
- 1. Set the canvas dimensions. Enter Width (px) and Height (px) for the image you need. Match these to whatever a form, mockup or design spec requires, such as 800 by 600 for a standard placeholder.
- 2. Pick a background and an optional label. Choose a Background color for the solid fill, then optionally type a Label such as the dimensions themselves and pick a Label color so it reads clearly against the background.
- 3. Generate and download custom.jpg. Click generate to render the exact size and colors you chose. Download custom.jpg and drop it into a design file, a CMS field or a test fixture wherever a real image is required.
When to use Create a Custom JPG
Create a Custom JPG builds a solid-color placeholder image at any width, height and label you specify. It replaces guessing with a real file when you need to test a layout, fill a gap in a mockup or stand in for an image asset that has not shipped yet.
- Filling a layout before real photos arrive. A web page template has three image slots but the client hasn't sent final photography. Generate gray placeholders at the exact target dimensions so the layout renders correctly today.
- Testing an upload form's size limits. You need to confirm your app rejects images above a certain resolution. Create a JPG at exactly 4000 by 3000 with a label showing the size, then upload it to verify the check works.
- Building a dummy asset for a CMS import. A bulk content import script expects an image URL for every record, but some records lack real photos. Generate labeled placeholders so the import doesn't fail on missing files.
- Demonstrating aspect ratio in a design review. You want to show a stakeholder what a 16 by 9 banner slot looks like before the artwork exists. A labeled placeholder at that exact ratio communicates the shape instantly.
Examples

Input
800×600, gray, label “800×600”

About the Create a Custom JPG tool
Create a Custom JPG is a free online tool that works entirely inside your web browser. Generate a JPG 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 145 JPG 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.
