In the first update to the encoders in years, I’ve changed them to be completely client-side only.
Now, what you want to encode and decode is transformed directly in your browser, not sent to my server for processing.
This should be more secure (you don’t need to worry about me snooping on files that are sent, or anyone watching your network traffic) as well as faster (only dependent on your browser speed, not your network connection).
Of course this comes at a cost. Support for some of the APIs I used is patchy across browsers. It uses HTML5, so will probably never work in Internet Explorer. Edge has made some stupid security decisions around base-64 links so downloading encoded/decoded files won’t work in it. Other browsers might be better. I use Chrome and it seems to be OK in that. I really should check Firefox at some point…
If you really like or hate the new approach, let me know on Twitter.
