Transparent PNG and Blank Image Generator
Create a fully transparent PNG or a solid-color PNG or JPG at exact dimensions, entirely in your browser.
Create a transparent image
Choose Transparent PNG, set the exact width and height, and download a PNG whose pixels have zero opacity. The checkerboard is only a preview of transparency and is not drawn into the downloaded file. Transparent mode uses PNG because JPG cannot store an alpha channel.
A blank transparent canvas is different from removing the background of an existing photo. Use the solid-color background remover when you need to process an image that already has a flat background.
About this tool
This 400x400 black image maker creates a plain solid-color picture instantly, with no account, upload, or design software. Use it for placeholders, app tests, social profile experiments, loading blur backgrounds, simple JPEG black files, light image blocks, and layout checks. The generator is 100% free, runs in your browser, nothing is uploaded, and every download is created from a local canvas.
Pick transparent mode or a named preset such as black, white, or light color, choose 400x400, 500x500, 1080x1080, or a custom size, then download locally.
The output canvas uses fixed pixel dimensions, so the downloaded file matches the width and height you choose. That makes the page handy for app placeholders, profile tests, quick backgrounds, and design QA where exact size matters.
400x400 Black Image
Choose the 400x400 preset and the black swatch to make a square black image for testing avatars, placeholders, graphics, or JPEG black output.
Light Color and Light Image Presets
Use the white, soft blue, warm light, or custom hex options when you need a light color block for backgrounds, loading blur placeholders, or clean design mockups.
