Base64 To File Extensions

Convert selected base64 data into downloadable files from the right-click menu.

Base64 To File Extension helps you turn base64 file data from webpages into downloadable files with a right-click. Select a base64 string, right-click, and choose “Base64 to File Download.” The extension checks the selected data locally, identifies the file type when possible, and saves the result with an appropriate file extension. For long base64 values wrapped in double quotes, the extension can help select the full quoted value when it appears to be downloadable file data. This is useful when working with API responses, logs, JSON output, dashboards, and other developer-facing pages. Key features: - Convert selected base64 data into files from the right-click menu - Detect common downloadable file types automatically - Support base64 data URLs - Help select complete double-quoted base64 values when applicable - Process data locally in your browser - No uploads, tracking, or external conversion service This extension is useful for developers, QA engineers, data analysts, and anyone who needs to inspect or extract base64 file content from web applications or API responses.
