Frequently Asked Questions
What is Base64 encoding used for?
Base64 converts binary data (like images) into text that can be safely transmitted in emails, JSON, HTML, and URLs. It's commonly used to embed images directly in HTML/CSS and to transmit files through text-only channels.
Does Base64 make files smaller?
No — Base64 actually increases file size by about 33%. It's not compression. Its purpose is to make binary data safe for text-based systems. For compression, use our Image Compressor instead.
Is Base64 encoding secure?
No! Base64 is encoding, not encryption. Anyone can decode it instantly. Never use Base64 to "protect" passwords, API keys, or sensitive data.
