When 100KB is the right target
One hundred kilobytes balances quality and compliance for many university admission portals, professional licensing boards, and government photo upload systems. Unlike generic compressors, target-size mode hits the exact byte cap without manual trial-and-error. Passport-style headshots, document scans, and profile photos typically retain readable detail at 100KB when properly lit and cropped.
Compress to 100KB step by step
Upload your image, select 100KB target, preview, and download. If the source is a large PNG, convert to JPG first to reduce overhead from the alpha channel. For passport photos, crop to the correct dimensions with our Passport Photo Maker before compressing. Keep originals archived — compressed files are for upload only.
