Image Compression vs. Resizing
Optimizing images for web speed involves two distinct strategies:
Reduces pixel width and height—for example, scaling a 4000 × 3000 camera photo down to 1920 × 1440 Full HD. Since total pixel count is halved, raw memory size shrinks proportionally.
Retains pixel dimensions while psycho-visually optimizing subtle color frequencies. At 80%–85% quality, images look virtually identical to the human eye while saving up to 80% file weight.
All scaling and encoding algorithms execute directly in client-side HTML5 Canvas. Your private family photos and confidential images are never transmitted across the network or saved on any server.
