EZGif
The internet's GIF workbench since forever — make, resize, crop, optimise, reverse and caption GIFs, convert video to GIF and back, and tweak APNG and WebP, all free with no account. ezgif.com ships a standalone manifest with a full icon set, so it installs as a quick-access media tool from the browser.

EZGif, as it opens in a browser tab.
Not sure how to add EZGif to your home screen? Step-by-step for Chrome, Safari, Firefox and Edge — it takes about ten seconds, and there is no app store involved.
