Frequently Asked Questions (FAQ)
Q1. What is Base64 and why does it matter for images?
Base64 is a binary-to-text encoding standard that lets you encode image files into a text string, so you can embed the image directly into HTML or CSS. Wikipedia+2Wikipedia+2
Q2. Will converting images to Base64 make them smaller?
Not necessarily — in fact Base64 encoding usually increases the size by about 33% because of encoding overhead. Stack Overflow+1 Use Base64 mainly for small assets or inline use, not large images.
Q3. Where should I use the Base64-encoded image?
Common use-cases: embedding small icons in CSS (background: url(data:…);), including images in email templates (to avoid blocked external images), or bundling assets in JS/HTML without separate files. jam.dev+1
Q4. Are there downsides to using Base64 images?
Yes — larger size (compared to binary image), potential caching inefficiency (separate files can be cached independently), and readability/maintenance of code can suffer. Avoid for large images. Medium
Q5. Is this tool free and safe to use?
Yes — it’s free and runs in the browser. You upload an image, get a generated string. Ensure you trust the site if you upload sensitive images.
