The company behind it (https://transloadit.com/ https://transloadit.com/) is also impressive. > We handle file uploads, resize, crop and watermark your images, make GIFs, transcode your videos, extract thumbnails, generate audio waveforms, and so much more. All that with a generous free tier. (Obs.: I'm not related to these people, had never heard of them until now.)
