Base64 Encoder/Decoder: Inline Small Icons and Captchas in Mobile H5
Slow mobile H5 pages often stem from small icons making requests. Base64 Encoder/Decoder converts text and images locally, inlining images into code.

Building mobile H5, load speed is hypersensitive: a few dozen-KB icons and decorative images, each firing a request, add up to slow first paint.
Base64 Encoder/Decoder converts those small images into Base64 strings to inline directly in CSS or HTML, removing extra requests; it also restores Base64 images from an API for inspection.
It's practical for lightweight H5, offline pages, and carrying small images through restricted environments, all on your machine.
One request saved is a little faster first paint. Bookmark Base64 Encoder/Decoder and make mobile pages lighter.
