Free Base64 to Image Converter

This converter transforms Base64-encoded strings back into viewable images directly in your browser tab. Just paste your raw Base64 text or a complete data URI, and the decoded result will appear instantly in the preview panel. You don't need to worry about manual configuration because the tool automatically identifies the correct format, whether it is PNG, JPEG, GIF, SVG, WebP, or BMP, by inspecting the header bytes. If you prefer, you can also upload text files containing encoded data or simply drag them into the workspace. Once your image renders, you can zoom in to check details, copy it to your clipboard, or save it as a local file. All processing happens on your device, ensuring your data never touches a remote server.

Auto Format Detection

Identifies PNG, JPEG, GIF, SVG, WebP, and BMP from header bytes. No need to specify the image type manually.

Data URI Support

Accepts both raw Base64 strings and complete data URIs with MIME type prefixes.

File Upload

Upload .txt, .b64, or .base64 files containing encoded image data. Drag-and-drop is also supported.

Zoom and Inspect

Zoom in and out of the decoded image with precision controls. View dimensions, format, and file size at a glance.

Download and Copy

Save the decoded image as a file or copy it directly to your clipboard for use in other applications.

How to Decode Base64 to Image

Begin by pasting your Base64 text into the input panel on the left. Once you click "Convert to Image," the decoded version will show up in the preview area on the right side of your workspace. If you're working with a full data URI, just copy the whole string, including the data:image/png;base64,... prefix. For raw text without a prefix, the converter reads the first few characters to identify whether it's a PNG, JPG, or another common format. You'll also see useful metadata like dimensions, format type, and file size displayed right above your image as soon as it's ready.

Online Base64 to Image Converter with File Upload

If your data is stored in a file rather than on your clipboard, you can upload .txt or .b64 files directly. Just click the Upload button or drag the file into the tool. This feature is especially handy for visualizing API responses or images extracted from log files without manually copying long strings. All file reading is handled through your browser's local API, meaning your data stays strictly on your computer.

Clipboard Paste Support

You can also use the Paste button to quickly pull Base64 text from your clipboard. If you've copied an actual image, like a screenshot, the tool can read that data directly and display it for you right away. This makes it simple to verify encoded images from developer tools or check screenshots without saving anything as a temporary file.

Zoom, Inspect, and Download

The preview panel has zoom controls to help you inspect images at any scale. Zooming in lets you look at pixel-level details, while zooming out gives you a full overview of larger files. Transparent areas in PNG or WebP files are easy to spot against the checkerboard background. When you're happy with the result, save your file or copy the image back to your clipboard. The tool even sets the correct filename extension based on the image type it detected.

Supported Image Formats

Whether you're working with PNGs, JPEGs, or GIFs, this converter handles almost any common image format found in Base64 strings. PNG files will keep their transparency, while JPEGs render at their original quality. Even animated GIFs are supported depending on your browser. For those working with web assets, SVG and WebP content decode smoothly into their respective scalable or high-efficiency forms. The tool identifies these formats by checking the unique file signatures at the start of your data, making the process seamless.

Common Use Cases for Base64 Image Decoding

Developers often find Base64-encoded images in JSON responses, CSS stylesheets, or database records. Visualizing these strings without writing extra code or saving temporary files is a huge time-saver. Designers can also use this tool to quickly verify that their data URI assets match their designs before they go live.

Free Online Base64 to Image Converter for Developers

Whether debugging an API that returns image data as Base64, inspecting CSS data URIs, or verifying email attachment encoding, this tool provides a frictionless workflow. There is no signup, no file size limit imposed by a server, and no watermark on downloaded images. Your encoded data stays in the browser tab and disappears the moment you close it. The client-side architecture means large Base64 strings process without upload delays, and sensitive image data like medical scans or internal documents never leaves your machine. Bookmark this converter and keep it ready for the next time encoded image data crosses your workflow.

Privacy and Client-Side Processing

Your images stay private because every step of the decoding process happens right on your machine. The Base64 strings are handled by native browser functions that render the results as standard images without sending anything over the network. No cookies, no server logs, and no stored sessions. Closing your tab simply erases the data. This makes it a safe way to check proprietary or sensitive images without any risk of leaks.
