10015 is a useful website containing a ton of quick little web tools that handle a set of fairly mundane but cropping up surprisingly often computing tasks, mostly around text and images.
Some examples include mini tools that:
- change the case of text
- resize or crop images
- format code
- encode URLs
- get a colour code from an image
- pixelate part of a photo
and much more.
Saves you downloading a ton of single-use apps or attempting to penetrate multiple websites full of interstitial adverts to get your job done.
