The resizing process doesn't introduce any compression artifacts but there is some loss when the images are processed by CLIP, depending on the dimensions. CLIP likes perfect squares, so that's a limitation on the model size. In terms of general compression are you familiar with FFmpeg? It has support for lossless compression into a bunch of different image formats.
