BASE64 to Blob

**pdiddles03** · 04-13-2016, 03:10 PM

I'm working on an app. I'm allowing users to upload photos which takes the photo, re-sizes the quality and size in canvas, then saves it as a base64 to store into the DB. When I pull it back out, should I convert it to a blob or should i just use the base64 string as an image src?

base64 is a text, not binary AFAIK.

That wasn't an answer. FYI base64 can be converted to binary.

Yeah, right.
but why? img src can accept image filename or... base64. Have a loook in here:

My question was, is it more resource intensive because of the length of base64?

Given you are posting this under JS programming, I'd suggest sticking with base64 just because JavaScript inhales upon the proverbial equine of short stature when it comes to dealing with binary encoded data.

But the question really is WHAT sort of database are you storing it in, HOW are you using it, and why are you putting it into a DB instead of a real file in the first place?

Still, there is toBlob -- if you want to use it as blob I'd be doing that before storing it just to save that extra 2/8ths+ overhead... but really things like canvas to image illustrates quite well how pathetic JS implementations still are for things like this.

Thanks for no answer...

Sorry, but could you clarify/answer the three questions in the middle of my response? You failed to provide enough information on WHAT, HOW or even WHY in the first place for anyone to give you a meaningful answer!
