Frequently Asked Questions
What is Base64 encoding?
Base64 is a way to represent binary data (like images or files) using only safe, printable text characters. It is commonly used in email attachments, data URLs in CSS/HTML, and API data exchange.
Is there a file size limit?
Since our tools run in your browser, the limit depends on your device's memory. For most tasks, files up to 10-20MB are handled smoothly. Larger files might cause sluggishness.
Is my data uploaded to a server?
No. We prioritize your privacy. All encoding and decoding operations are performed using JavaScript directly on your computer. Your files and text never leave your device.
