Image to Base64 Converter

Convert an image file into a Base64 data URL directly in the browser.

About this tool

Encode images as Base64 strings for inline assets, previews, testing, and quick front-end workflows.

Image to Base64 is useful when a local asset needs to become an embeddable string for HTML, CSS, API payloads, or quick transport. It helps with lightweight prototypes, email snippets, docs, and debugging workflows that depend on inline image data.

  • Reads image files locally in the browser.
  • Shows a preview alongside the generated Base64 string.
  • Useful for HTML embeds, CSS testing, and quick asset transport.

How to use Image to Base64

Upload the image, review the generated Base64 output, and copy it into the target data URI, request body, or embed field. If the file is large, check the output size before using it because Base64 inflation can make inline images heavier than expected.

When this tool is useful

  • Reads image files locally in the browser.
  • Shows a preview alongside the generated Base64 string.
  • Useful for HTML embeds, CSS testing, and quick asset transport.

    Frequently asked questions

    Does my image upload to a server?

    No. The file is read locally in your browser only.

    What output format do I get?

    The tool returns a Base64 data URL that includes the image MIME type prefix.

    Can I generate a specific number of words instead of full paragraphs?

    Yes, you can switch the output unit between paragraphs, sentences, and words, and specify the exact count you need for precise placeholder sizing.

    Does the generated text always start with Lorem ipsum dolor sit amet?

    The first paragraph starts with the traditional Lorem ipsum opening by default. Subsequent paragraphs use randomized Latin-style text to avoid repetition.

    Is the output wrapped in HTML paragraph tags?

    By default the output is plain text. You can enable an HTML option that wraps each paragraph in <p> tags, making it ready to paste into CMS editors or HTML templates.

    Does the Base64 output include the data URI prefix for direct use in HTML?

    Yes, the output includes the full data URI with the MIME type prefix such as data:image/png;base64, so you can paste it directly into an img src attribute or CSS background property.

    How much larger is the Base64 string compared to the original file?

    Base64 encoding increases the data size by approximately 33%, so a 100 KB image produces a roughly 133 KB Base64 string. Keep this in mind for page weight if embedding inline.

    Is there a risk of my image being sent to a remote server?

    No, the conversion runs entirely in your browser using the FileReader API. The image data stays on your device and is never transmitted over the network.
