Tech specs
Input: plain text, raw Base64, Data URI strings, or uploaded files. Output: encoded text, decoded text, or downloadable decoded file output.
Check supported input/output details and follow the tool steps before exporting.
01
Choose text mode or file mode, then switch between Encode and Decode.
02
Paste text or Base64 data, or load a file to convert.
03
Optionally keep the Data URI prefix when encoding file content.
04
Copy the output or download the decoded file directly from the browser.
Understand how to encode Base64 files and text, why it matters in repeat workflows, and when to use this tool with confidence.
Encode or decode Base64 for text, raw payloads, Data URI strings, and files in one browser-based workflow with no uploads. That makes it a practical fit when you need encode binary assets for embeds or fixtures, decode base64 payloads from apis and logs, and create or strip data uri strings for front-end work.
Instead of switching between separate utilities, the current workflow keeps the main task, supporting controls, and export actions together so you can validate the result before moving on.
Choose text mode or file mode, then switch between Encode and Decode. Paste text or Base64 data, or load a file to convert. Optionally keep the Data URI prefix when encoding file content. Copy the output or download the decoded file directly from the browser. The goal is to keep the path from input to verified output short enough for quick tasks while still exposing the controls that matter when the data is more sensitive or more complex.
Handles both text and file workflows in one tool. Supports raw Base64 strings and Data URI output. Lets you download decoded file output immediately. Runs entirely in the browser for private debugging and handoff tasks. That combination makes the tool useful for both one-off fixes and repeat operational work, especially when you want to keep the workflow inside the browser.
People often land on this page looking for encode Base64 files and text, base64 encoder decoder, or decode Base64 online. The reason the tool holds up in practice is that the copy matches the real implementation instead of promising features the interface does not support.
When the visible content stays aligned with the shipped behavior, the page is easier to trust, easier to localize, and easier to reuse as the tool evolves.
