IMO ImageMagick on the commandline is more straightforward:
convert -resize X input.jpg output.jpg
Where X is either a specific output resolution (eg, "640x480") or a relative scale ("50%"). No cloud required!
Input and output filetypes are automagically determined by fingerprint and extension, so conversions like gif-to-jpeg "just work". Current versions even support the newfangled "webp" format that's being used by some websites. There's about a zillion other options, so spend some quality time with the documentation.
