About ShrinkToKB

ShrinkToKB does one job: compress an image to an exact file-size target — 20 KB, 50 KB, whatever your form demands — entirely inside your browser.

It exists because of a gap between two facts. First, millions of people every year face upload forms with hard KB limits: exam applications, government portals, job boards, visa systems. Second, the photos those forms want — your face, your signature, your documents — are exactly the images that should never be uploaded to an anonymous "free tool" server for processing.

The fix is architectural, not cosmetic. This site is static: there is no upload endpoint, no processing queue, no account system. Your browser does the compression using its own built-in image machinery, which is why the tool works offline and why the privacy claim can be verified in two minutes rather than taken on faith.

Principles

• Local only. Files never leave your device. Not "deleted after" — never received.
• Exact, not approximate. The tool targets your byte limit precisely and tells you the true output size.
• Free without a catch. No signup, no watermark, no daily cap. Your device does the work, so serving you costs almost nothing.
• Honest about trade-offs. When a target requires shrinking dimensions or costs visible quality, the tool says so instead of pretending.

Who makes this

ShrinkToKB is built and maintained by an independent developer as part of a small family of single-purpose, local-first browser tools. It may eventually show unobtrusive ads to cover its costs — if it does, they will sit outside the tool and will never see your files, because the no-upload architecture doesn't change with the funding model.
