About This Tool

The Base64 to Image Converter decodes a complete image data URL or raw Base64 text into a browser preview. When raw text is used, a MIME selector supplies the expected image type before download.

ToolPool runs this utility in your browser, so your input stays on your device and is not uploaded to our server.

How To Use This Tool

  1. 1Paste an image data URL or raw Base64 value.
  2. 2Choose the MIME type when the prefix is absent.
  3. 3Decode, inspect dimensions, and download the image.

Creates a local downloadable file.

Common Use Cases

  • Recovering an embedded image.
  • Testing image API payloads.

Workflow Tips

Base64 to Image is designed for quick browser work, but it is still worth reviewing the result before you use it in a live project, client document, public page, or production workflow. Keep an original copy of important source material, compare the output with what you expected, and repeat the task with slightly different settings when quality, formatting, or accuracy matters.

For larger workflows, pair this page with Image to Base64, Base64 Encoder, Image Converter, Image Metadata Viewer. Moving between related utilities can save time when you need to clean source data, prepare web assets, create supporting IDs, check calculations, or package output for another system. Internal links also make it easier to stay in one private workspace instead of jumping between several single-purpose sites.

The local processing model helps protect sensitive content because ToolPool does not need to receive your files, text, or form values to complete the task. Good privacy habits still matter after the result leaves the page: avoid pasting unnecessary secrets, check downloaded files before sharing them, and clear the workspace when you are finished on a shared computer.

FAQ

Why is a MIME type needed for raw Base64?

Raw text does not identify the image format, so the browser needs a media type such as image/png to interpret it.

What causes a decoding error?

Missing characters, invalid Base64 symbols, an incorrect data URL, or bytes that are not a supported image can prevent a preview.

Does decoding contact a server?

No. The text is decoded and previewed with browser capabilities on your device.
