PixKB exists because of a specific, maddening moment: you're filling out an application form — a job portal, a visa system, a university admission — and your photo upload fails. "File too large." "Invalid dimensions." "Minimum size not met." The deadline is tonight, the error message doesn't explain itself, and every tool you try either uploads your photo to someone's server or buries the one function you need under ads.
PixKB does one job precisely: it gets your image to the exact file size and dimensions a form demands. Compression to an exact KB target, resizing in real-world units with correct DPI math, format conversion, and one-tap presets for specific portals whose requirements we verify against official sources — the verified badge on a preset means we read the portal's actual published spec, not a figure copied from another website.
Everything runs in your browser. Your photo is never uploaded to us — there is no server that could receive it. That's not a marketing line; it's the architecture.
The site is free, supported by ads that stay out of the tool's way.
