PixelToKB is a browser-based toolkit for compressing JPEG, PNG, and WebP files to preset or custom size limits. It checks the generated file’s actual byte count before download and also includes resize, crop, lossless PNG optimization, file-size, pixel, transparency, aspect-ratio, PPI, and DPI inspection tools. Selected images are processed locally and are not uploaded to a PixelToKB server. No account is required.
