Why Compress Images to 100KB?

Online portals, university admission forms, recruitment websites, and email systems often enforce a strict 100KB file size ceiling. Uploading an image even one kilobyte over this limit results in rejected uploads and frustrating error messages.

Our smart compression tool automatically balances perceptual clarity and file weight to guarantee your images stay strictly under 100KB without visible blur or pixelation.
