Dimensions vs. File Weight
Resizing changes pixel width and height. Compression changes how compactly those pixels are stored on disk. By resizing first to sensible dimensions (e.g. 1000px wide), achieving a 100KB file size requires almost no noticeable visual compression.
Resizing to 100KB Step-by-Step
Upload your file to our [Resize Image to 100KB](/resize-image-to-100kb/) page. The tool inspects your original dimensions and runs a dual-pass algorithm to scale down excessive width and height while optimizing JPEG quantization to stop just shy of 100KB.
