Image Converters & Generators Tools

Image to Base64 Converter handles the case that trips up more projects than any other: an image that has to travel through JSON, a CSS data URI, or a Markdown file that cannot carry file references. Drop the image in, get the data: URL string out. The encoded output is copy-ready for an <img src=…> attribute or a background-image declaration — the length figure alongside tells you whether the result is practical or whether you should link the file instead.

Aspect Ratio Calculator and Placeholder Image Generator address a quieter version of the same problem: the right proportions set before an image exists, not retrofitted afterwards. Placeholder Image Generator produces a real PNG with the exact pixel dimensions you specify, so a layout test uses a real network request with real dimensions rather than a broken-image icon.
