ShrinkImage Bot
ShrinkImage Bot (@shrinkimagebot) is unusually specific for this category: its own bio states it can "compress JPG, PNG, WEBP files by up to 90%. Free, no watermark, no registration." That kind of concrete number and explicit no-watermark promise is a stronger trust signal than the vague "compress your images" pitch most similar bots use.
The use case is straightforward: you have a photo or screenshot that is too large to send comfortably, attach to an email, or upload to a form with a size limit, and you want a smaller file without visibly ruining the picture. Send the image, receive a compressed version back in the same chat.
Because compression is lossy by nature, very high compression ratios on already-compressed JPEGs can introduce visible artifacts; for the cleanest result, start from the original, uncompressed photo rather than a version that has already been through another compressor.
