About this tool
Get a 1 × 1 transparent PNG or GIF, the tiny spacer and tracking image used in emails and web pages, or a single pixel of any color and opacity. The files are written byte by byte, so they are as small as possible and the color is exact.
Both the PNG and the GIF are shown as Base64 data URIs with their exact sizes, ready to copy into HTML or CSS. You can also make slightly larger solid images up to 256 × 256 pixels.
- Works on your device. Nothing is uploaded.
- Free, with no sign-up and no watermark.
- No limits on file count or size beyond what your device can handle.
