About KBWise
Built around one moment of frustration: “File too large to upload.”
The problem we work on
Somewhere right now, a form is rejecting somebody’s file. A visa portal wants the photo under 100KB. An exam board wants the signature between 10 and 20KB. A job application wants the certificate as a PDF under 200KB. The person uploading doesn’t care about compression algorithms — they have a deadline, and the form just said no.
KBWise exists for exactly that moment. Every tool here starts from the rule you’re trying to satisfy — an exact KB size, exact pixels, a format — and works backwards to the best file that passes it.
What makes it different
- Your files never leave your device. The tools are JavaScript running in your browser. There is no upload step in the code — not a promise, an architecture. We couldn’t see your files if we wanted to.
- Exact targets, not vague “levels”. Forms enforce numbers, so our tools hit numbers.
- Honest failures. When a target physically can’t be met at usable quality, the tool says so and tells you what to change — it never hands you a silently ruined file.
- No accounts, no watermarks, no daily limits. The free tools are simply free.
Who runs this
KBWise is a small independent project — no venture funding, no growth team, no data-harvesting business model behind it. The site is monetized the boring way: unobtrusive ads (Google AdSense) and, later, an optional paid tier for bulk features (see Pro). Ads never touch the tools — your files still never leave your device — and the free single-file tools stay free.
This website is served from servers in the United States (North Carolina). Your files, again, never travel to them.
