Base64 एनकोडर / डिकोडर
टेक्स्ट (UTF-8 सुरक्षित) और फ़ाइलों के लिए Base64 एनकोड और डिकोड करें, URL-सुरक्षित आउटपुट के साथ। सब कुछ स्थानीय रूप से चलता है।
उपयोग कैसे करें
Text is encoded as UTF-8, so non-ASCII text works as-is. The URL-safe option replaces + and / with - and _ and drops the = padding. To encode a file, just pick one (10 MB cap) — you also get a ready-made data URL. To turn Base64 back into a file, paste it into the input, set the MIME type and use the download button.
टिप्पणियाँ
Everything is processed in your browser; files are never uploaded. Decoding to text validates the result as UTF-8, so arbitrary binary data may fail with an error — use the download button for binary content instead.
