What this tool does

Image to Base64 Online helps you convert from one format or unit to another. It focuses on the exact task promised by the page title, while still allowing useful options such as output choices, unit changes, quality settings, or copied results when supported.

How to use it

Add or enter image files, choose the needed options, then run the tool. Review the result, download the output when a file is created, or copy the text result when the page produces data.

Best practices

Use PNG when transparency matters, JPG for photos, and WEBP for smaller web images. Higher quality usually means a larger file size. Batch conversion is useful when many images need the same output format.

Quick checklist

Confirm the input file, value, text, or measurement is correct before running the tool.
Use the visible dropdowns and settings to choose the output format, unit, quality, size, or result style.
Check the preview, result text, or downloaded file before using it for important work.
For private or sensitive data, prefer browser-based tools and avoid uploading files unless the tool clearly needs server processing.
