Browser-local processingNo account requiredFree to use Original stays unchanged

Why this tool exists

Base64 makes the payload roughly one-third larger, so it is best for small assets rather than large photographs.

  • ✓ data URI output
  • ✓ raw Base64 output
  • ✓ copy to clipboard
  • ✓ download text

Useful for

  • • CSS backgrounds
  • • HTML prototypes
  • • API and JSON fixtures

The goal is not to add another generic converter. It is to remove a small but real step from a document, design or developer workflow.

A practical MAXScanner tip

Keep the original file until you have checked the destination requirements. A good workflow is usually: inspect → transform → verify → download → then compress or convert again only if the destination requires it.
