Compress image to 300KB
Quick answer
300KB leaves real headroom, ideal for content-rich photos and large web images — keeping a finer picture while staying easy to upload.
300KB suits images that carry a lot of detail you don't want to lose: landscapes, group shots and dense web heroes. Drop an image in and image cat compresses it toward 300KB locally — never uploaded.
When to choose 300KB
When 100–200KB compresses a photo too hard and detail visibly drops, loosening the target to 300KB often fixes it instantly. Colour gradients, texture and small distant objects survive better, while the size still suits the web and most uploads.
300KB and page load
300KB is still lightweight for a modern web page, and pairs with WebP for fast loading. For a large in-article image, 300KB is a good balance between quality and speed.
