    About this tool

    Create a PNG image at any size, in any colour, in one click, with no editor, no account and no watermark. This is the tool you want when you need a plain image rather than a photo: a placeholder while a design is in progress, a solid background for a slide or thumbnail, a colour swatch to check against a palette, a spacer for an email template, or a correctly sized canvas to hand to a designer. Presets cover the sizes that are annoying to remember: Instagram post and story, Facebook cover, Twitter header, HD, 4K, square and thumbnail. Custom dimensions accept anything up to 4000 pixels per side. The image is drawn in your browser with the Canvas API and downloaded directly. Nothing is uploaded, nothing is generated on a server, and nothing is stored.

    Frequently asked questions

    How do I create a PNG image of a specific size?

    Enter your width and height in the Custom Size fields, choose a background colour, and click Generate & Download. Any size up to 4000 × 4000 pixels works.

    Can I make a PNG with a transparent background?

    Yes, select Transparent in the Background section, or use the dedicated Transparent PNG Generator. The saved file keeps a genuine alpha channel, not a white fill.

    Is there a watermark on the generated image?

    No. The PNG contains exactly what you specified and nothing else: no watermark, no metadata, no attribution requirement. It is yours to use commercially.

    What is the maximum size I can generate?

    Up to 4000 pixels on each side. Larger images take longer to render because the work happens on your own device rather than a server.
