Base64 data URL

Convert an image to a Base64 data URL

A Base64 data URL stores image data as text that can be embedded directly in HTML, CSS, JSON, or a test fixture. This converter reads a supported image in your browser, shows a preview, and produces a copy-ready data URL without uploading the file.

What does Image to Base64 do?

It accepts common PNG, JPEG, GIF, WebP, and SVG image files up to the stated size limit. The browser reads the file and outputs its media type and encoded content in one data URL. Base64 does not compress or improve an image; it only changes how the bytes are represented.

How to convert an image

  1. Select a supported image from your device.
  2. Confirm the preview is the file you intended to use.
  3. Copy the generated Base64 data URL.
  4. Paste it only where a complete data URL is accepted.

Who is it useful for?

Frontend developers can embed tiny assets, email developers can prepare compatible resources, and QA teams can create self-contained samples. It can also help with API prototypes or documentation where attaching a separate image file is inconvenient.

When should you avoid Base64 images?

Base64 output is roughly one-third larger than the original binary data and large strings are difficult to maintain. For normal website photography and sizable graphics, a separate optimized image file is usually easier to cache, update, and deliver efficiently.
