FAQ — Image-to-Base64 (I64)
Short answers to common questions. Click a question to reveal a concise answer.
Simply upload an image or paste Base64 text, click the "Encode" or "Decode" button, then copy or download your result. The entire process happens in your browser.
No. All encoding and decoding happen in your browser using JavaScript. Your image never leaves your device unless you explicitly share it elsewhere.
All common formats are supported: PNG, JPG, JPEG, GIF, SVG, WebP, BMP, and ICO. The tool reads any image file as binary data for encoding.
Switch to "Decode" mode, paste your Base64 string (with or without data URI prefix), click "Decode", and the image will appear. You can then download it or copy it to clipboard.
Yes! After decoding, use the "Copy" button to copy the actual image (not Base64 text) to your clipboard. You can then paste it directly into social media posts, emails, or messaging apps.
Base64 encoding increases file size by approximately 33% because it converts binary data into ASCII text characters. It's best for small images like icons and logos.
Choose from multiple formats: Data URI (ready to use in HTML), Plain Base64, HTML Image Tag, CSS Background, React Component, or Vue Component. Select your preferred format before copying.
Base64 is an encoding, not encryption. It's easily reversible and provides no security. Don't use it to protect sensitive images—use proper encryption instead.
Ensure your Base64 string is valid and complete. The tool accepts Base64 with or without the data URI prefix (data:image/png;base64,). Try removing extra spaces or line breaks.
