Data URI Decoder: Decode Text and Download Binary Files
The Data URI Decoder parses a data: URI (RFC 2397) and separates its MIME type, charset, and encoding before decoding the payload. Text results appear inline with a copy button, while binary content such as images is offered as a download; the file type is detected from its magic bytes. Use it to inspect a URI and recover its content.
The Data URI Decoder is a browser-based tool for decoding data: URI values. It parses a data: URI according to RFC 2397, identifies its MIME type, charset, and encoding, and then decodes the payload. Use this data URI decoder online to inspect a value and recover its contents without installing a separate tool.
The conversion starts by reading the data: URI and its metadata. Decoded text is displayed inline with a copy button, so you can retrieve it directly. When the payload is binary, such as an image, the tool offers it as a download; the file type is detected from its magic bytes. The tool does not list configurable conversion options.
A data: URI carries data together with information such as its media type and encoding. Decoding helps when you need to read text that has been packaged this way or recover binary content for use as a file. Text can be viewed and copied, while binary output is provided as a download rather than displayed as text.
The decoder runs entirely in your browser: your input is processed on your device and is not uploaded, stored, or sent to a server. It is free, and once the page has loaded, it works offline without a server connection.
This tool can help developers and DevOps engineers who need to inspect, copy, or recover content from a data: URI. It is also useful when checking a value shared by a teammate or verifying that a text round-trip has not changed the content.
Step 1: Paste or drop the data: URI into the tool. Provide the complete URI value so it can parse the metadata and payload.
Step 2: Run the decode. The tool parses the URI and decodes its payload in your browser.
Step 3: Review the results. Check the MIME type, charset, and encoding shown for the data: URI.
Step 4: Copy recovered text when the payload is textual. The decoded text appears inline with a copy button.
Step 5: Download the result if the payload is binary. Binary content, including images, is offered as a file download with its type detected from its magic bytes.
Use case: Recover text from a data: URI someone sent you. Paste the value into the decoder and copy the recovered text from the inline result.
Use case: Move text through a channel that only carries data: URI values. Decode the value when it reaches its destination to retrieve the original text.
Use case: Check whether a round-trip preserved a value. Decode the data: URI and compare the recovered text with the original to check that the encoding was not lossy.
Use case: Inspect the MIME type, charset, and encoding of a data: URI. Reviewing these details helps you understand the metadata associated with its payload.
Use case: Recover binary content such as an image from a data: URI. The tool offers binary results as a download and detects the type from the content's magic bytes.
Use case: Examine a data: URI encountered while reviewing application data or a snippet of code. Decode it to see whether it contains inline text or downloadable binary content.
