Recover inline assets
Turn a copied data URI back into an image you can preview and download.
Documentation
Base64 to Image Decoder documentation
Decode Base64 strings or data URIs back into previewable image files with download-ready output.
Overview
Use it when the format needs to change, not the meaning
Use Base64 to Image Decoder when an image arrives as Base64 text and needs to become a real file again.
Inspect encoded image payloads
Confirm that a Base64 string really decodes into the image type and dimensions you expect.
Supported inputs
Bring clean source text and keep the direction straight
- Accepts full data URIs and raw Base64 image strings.
- Whitespace can be stripped before decoding, which helps with wrapped or pasted multiline payloads.
- The decoded output is validated before the tool shows a preview or download action.
Walk through it
Follow the same sequence you see in the tool
Workflow
Decode a Base64 image payload
Use this flow when you want to recover a pasted image string into a viewable file.
- Paste the Base64 string or data URI into the input field.
- Choose the download filename and keep whitespace stripping enabled when the payload is wrapped.
- Run the decode and review the preview, image details, and download action.
What you get
Check the result before you copy it into the next step
Image preview
A live preview confirms the decoded bytes produce a real image.
Download file
The decoded image is packaged with an appropriate file extension for download.
Image details
MIME type, file size, and dimensions help you verify the recovered image.
Avoid these mistakes
Small input problems create the biggest conversion errors
Pasting non-image Base64
The tool only previews payloads that decode into real image bytes.
Leaving wrapped whitespace intact
Turn on whitespace stripping when the payload contains line breaks or copied spacing.
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 value that combines a media type with Base64 content so an asset can be embedded directly.
MIME type
A MIME type is the file type label, such as `image/png` or `image/webp`, that describes what kind of image the decoded bytes represent.
