Image → Base64 documentation

Convert uploaded images into Base64 strings or data URIs with preview checks.

Overview

Use it when the format needs to change, not the meaning

Use Image → Base64 when a file needs to become an embeddable string or data URI.

Inline assets

Turn a logo or screenshot into a Base64 string for a text-only destination.

Embeddable previews

Generate a data URI when the next step expects one copyable value.

Supported inputs

Bring clean source text and keep the direction straight

  • Accepts JPEG, PNG, WebP, GIF, SVG, and BMP files up to 5 MB.
  • Drag-and-drop and browse upload both behave the same once the file is selected.
  • Wrap settings let you choose how the output is formatted for the next step.

Walk through it

Follow the same sequence you see in the tool

Workflow

Convert an image to Base64

Use this flow when you want a copyable encoded string or data URI.

  1. Upload the image you want to encode.
  2. Choose whether you need wrapped output or a data URI.
  3. Run the conversion and copy the result that matches the destination.

What you get

Check the result before you copy it into the next step

Base64 string

The encoded text is ready for plain-text fields or text-based workflows.

Data URI

A copy-ready data URI appears when you need the image inlined.

Metadata card

File type, size, and dimensions help you confirm the upload before you copy it.

Avoid these mistakes

Small input problems create the biggest conversion errors

Uploading the wrong file

Check the filename and preview before you copy the output.

Choosing the wrong output form

Pick Base64 text or a data URI based on the next destination.

Glossary

Decode the terms before you act on them

This section translates the most technical labels on the page into plain language so you can interpret the output without opening another tab.

Base64

Base64 is a text encoding that turns binary file data into characters that are easier to move through text-only systems.

Data URI

A data URI is an inline string that combines a file’s media type with its Base64-encoded content so it can be embedded directly.

Media type

A media type is the file type label, such as `image/png` or `image/svg+xml`, that tells the next system what kind of content it is receiving.
