Frequently Asked Questions
What is Base64 encoding?
Base64 converts binary image data into a text string that can be embedded directly in HTML, CSS, or JavaScript without needing a separate image file.
When should I use Base64 images?
Base64 is ideal for small images like icons, logos, and UI elements where you want to reduce HTTP requests by embedding the image directly in code.
Does Base64 increase file size?
Yes, Base64 encoding increases the data size by about 33%. It is best used for small images where the convenience outweighs the size increase.
What format is the output?
You get a complete data URI string (data:image/png;base64,...) that you can paste directly into an HTML img src or CSS background-image.
Is this tool really free?
Yes, completely free with no hidden fees, no watermarks, and no sign-up required. You can convert as many files as you need.
Are my files private and secure?
Absolutely. Every conversion runs in an isolated, in-memory process. Your files never touch the disk, are never stored or shared, and are deleted from memory the moment your download is ready.
