Frequently Asked Questions (FAQ)
Are my uploaded images saved to your servers?
Not at all. ToolVill's Image to Base64 converter is a completely client-side application. The images you select are processed solely within your browser and never leave your device.
Does converting to Base64 reduce my image quality?
No. Base64 encoding simply translates the exact binary data of the original image into a text format. There is absolutely no loss of quality, resolution, or detail.
Should I convert all my website images to Base64?
No. Base64 encoding actually increases the file size of your image by approximately 33%. For large or high-resolution photos, it's significantly better to serve them as standard image files (like WebP or JPG) via a CDN. Base64 is best utilized for extremely small assets, such as icons or placeholders under 10KB, to save on HTTP requests.
