I usually go through my Flickr page (3rd party), but there are times for whatever reason I need to conform to the limit and post my photo directly. I must say, figuring out a way to resize my 20mb photo down to a 100kb copy from an iPhone has been a painfully frustrating journey.
I thought I had shared a few of these a while back, but I’m sitting here randomly browsing UER and I don’t see anything, so I’ll share it with you guys now (caveat: I just pulled these from my browser bookmarks so I don’t remember which ones are best). It’s still a pain in the ass of course to resize the photos, but it’s at least a simple pain in the ass if you can find someone else who did all the coding and is willing to share the reward of all that effort. A big advantage of using one of these or something similar, is that most sites will “sharpen,” your photo as well as find a way to make your photo a decent size on the screen without looking like utter crap at the end of the process. As I said, some sites do this better than others.
(Free!) Image Resizing Websites (there are apps that do this too if you dig a little bit). Many of these will do other stuff too if you want them to. https://www.imgonl...g/resize-image.php http://webresizer.com/resizer/ https://resizeimage.net
Never tried this last one, but it looks interesting at first glance (and it looks user friendly): https://www.xnview.com/en/
The learning curve varies mostly by experience, but also by the website itself, as does each site’s picture quality, features, and customization abilities. Try out more than one because I’ve noticed some of these are better at creating a decent end result and some aren’t so great. I suck at this stuff, so I prefer simple myself.
Lastly, if someone finds one of these that works decently with batches or maybe some kind of preset option, please share it with the rest of us! I’m still looking for something like that, but it’s probably just another pipe dream.
