Why there's no upload step
100KB limits show up on exam applications, visa portals, and government forms that expect a one-or-two-page scanned document. Hitting it means re-rendering each page as a compact image and rebuilding the PDF — this tool searches for the best quality that still fits, entirely in your browser, so your ID scans and certificates never touch a server.
Is my document uploaded anywhere first?+
No — compression happens entirely in your browser, which matters for the ID and certificate scans these portals ask for.
Can every PDF reach 100KB?+
A 1–2 page scan almost always can. Long or graphics-dense PDFs may not fit at readable quality — the tool tells you honestly when it could only get close, rather than silently mangling the pages.
Will text stay selectable?+
No — pages are converted to images to hit a target this tight, so text stops being selectable. Portals only check the file size, not the text layer.
What if the portal allows 200KB or 300KB?+
Use the matching target page — every extra KB of budget buys visible quality at these sizes.
