Python Image Resizer
Small script for editing images in bulk or one by one
Supports:
- Resizing without altering the aspect ratio,
- Cropping, crops images to the specified size, cropped from the middle
- Rotating, tries to rotate images the right way around (JPG only)
Supported filetypes are JPG/JPEG, PNG and GIF*
*Not recommended as output gifs come out larger in file size relative to originals

resolution [resolution ...]
Required
-i INPUT, --input INPUT Input file or folder
-o OUTPUT, --output OUTPUT Output folder
resolution output resolutions, <width>x<height> OR <width>
-r, --resize resize images, maintains aspect ratio
OR
-c, --crop crop images, centered,
NOTE: Skips images with width OR height smaller or equal to target
Optional
-h, --help show this help message and exit
-q [1-95], --quality [1-95] Picture quality, Value between 1-95, Default is 75
Pick one:
-AA, --antialias Uses Antialias/Lanczos as resampler, Slow (DEFAULT)
-BC, --bicubic Uses Bicubic as resampler, Fast
-BL, --bilinear Uses Bilinear as resampler, Faster)
-N, --nearest Uses Nearest as resampler, Fastest
-v, --verbose Enable detailed logging
-y, --yes Skip confirmation
-O, --organize Organize output resolutions in their own folders,
disables the resolution suffix on files
