How do I compress a PDF to exactly 200KB?

Choose the 200 KB preset and drop your PDF. Morphix runs an automatic quality search: it re-renders the pages at progressively lower resolution and JPEG quality until the output lands under 200 KB, then stops at the best-looking version that still fits.

Why do upload forms require 100KB or 200KB PDFs?

Government portals, university applications, job boards and visa systems often enforce hard per-file caps — typically 100 KB, 200 KB, 500 KB or 2 MB. A file one kilobyte over the limit is rejected without explanation, which is why an exact-size compressor is more useful than a generic quality slider.

Is my document uploaded anywhere?

No. The whole compression loop runs inside your browser tab using PDF.js and pdf-lib. Your PDF never touches a server, which matters for ID scans, contracts and medical paperwork.

What if my target is too small to reach?

Morphix tells you the smallest size it could reach and still offers that file. A 40-page scan cannot realistically fit in 100 KB — split it first, or raise your target.

Does text stay selectable?

No. To hit a hard byte target the pages are rasterised to images. That is the same approach desktop tools use for size-capped uploads. Use the standard PDF compressor if you need selectable text.

Compress PDF to an Exact Size (100KB / 200KB / 500KB)

Why an exact target beats a quality slider

Application portals, tax offices, visa systems and job boards enforce hard byte caps — 100 KB, 200 KB, 500 KB, sometimes 2 MB. A generic compressor gives you “about 40% smaller”, which is useless when the form rejects anything over 200 KB. Morphix instead runs an automatic search: it re-renders your pages at nine progressively lower resolution/quality combinations and stops at the first one that fits, so you get the sharpest document that still passes the upload check.

Everything stays on your device

Size-capped uploads are usually identity documents, diplomas, bank statements and medical forms — precisely the files you should not hand to a random cloud converter. Morphix does the entire multi-pass compression inside your browser tab. Open DevTools → Network and you'll see zero upload requests.
