Base64 to Image

Decode Base64 image data URIs into a preview and downloadable image file directly in your browser.

Your Base64 image stays in your browser.

Accepted: PNG, JPG, WebP, GIF, SVG ยท Max decoded size 10 MB. Raw Base64 without a data URI is previewed as PNG.

Decoded image preview

Base64 is encoding, not encryption. Anyone with the string can decode the image.

Paste a Base64 image string to preview and download it locally. No upload or account is required.

Base64 image decoding workflow tips

Decoding a Base64 image is most useful when you need to inspect a small data URI from CSS, HTML, JSON fixtures, tests, email snippets, or documentation examples.

Decode before editing

After decoding, use Image Resizer, Image Compressor, or Image Metadata Remover when you need a cleaner downloadable file.

Keep large assets as files

Base64 strings are often much longer than binary image files. Use this decoder for small assets, fixtures, and debugging rather than as a replacement for normal production image hosting.

Round-trip small examples

Use Image to Base64 to encode a small local image, then come back here to verify the data URI. For text payloads, use Base64 Encoder/Decoder or the Developer Data Toolkit.

What this tool does

Base64 to Image turns pasted data:image Base64 strings into a local preview so developers, QA testers, and documentation writers can inspect encoded image fixtures without uploading the data to a server.

Common use cases

Decode pasted Base64 image strings or data URIs into a browser-local preview and downloadable image file for debugging, documentation, and test fixtures.

Use Base64 to Image when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.

How to use it

  1. Paste a data:image/png;base64,... URI or a raw Base64 image string into the input box.
  2. Review the decoded preview, detected MIME type, decoded size, and input length.
  3. Download the decoded image file or copy the normalized data URI for your local workflow.
  4. Base64 is encoding, not encryption. Do not paste confidential image data into tools you do not trust.

Example workflow

Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.

Privacy note

Base64 to Image runs locally in your browser. Your pasted image data is not uploaded, stored, or sent to ClearUtils.

FAQ

Does Base64 to Image upload my data?

No. The Base64 image string is decoded locally in your browser and is not uploaded, stored, or sent to ClearUtils.

Can I decode raw Base64 without a data URI?

Yes. Raw Base64 image strings are accepted and previewed as PNG by default. A full data:image/...;base64 URI gives the most accurate file type.

Is Base64 a secure way to hide an image?

No. Base64 is reversible encoding, not encryption. Anyone with the string can decode the image data.
