Compress image to 200 KB

Two hundred kilobytes is the size a scanned page wants to be. It sits comfortably under the per-file limits on visa portals, HR systems and loan applications, yet stays large enough that printed text, stamps and signatures hold up when the reviewer zooms in.

Photo-quality targets like 20 or 50 KB are too aggressive for a full page of text — small print turns to mush — while an untouched scan from a phone or flatbed can run 3 to 8 MB per page, far too heavy to send a dozen at once. At 200 KB a ten-page bundle totals around 2 MB, which fits in a single email.

Documents fail differently from photos: what matters is that fine lines and small characters survive, not skin tone. Scan or shoot the page straight and evenly lit, then let the tool compress toward 200 KB.

Grayscale helps here — a black-text document in grayscale reaches 200 KB at a higher effective resolution than the same page in full colour, so switch colour off unless a stamp or highlight carries meaning. If a page holds dense small print, keep the resolution up and let quality drop instead; text tolerates lower quality far better than it tolerates being scaled down.

A 200 KB scan is almost always something private — a passport page, a payslip, a signed agreement. All the compression happens locally on this page, so the file is never uploaded, cached on a server, or shared; it is read from your disk, resized in memory, and written straight back. You can run a whole folder of scans through in one pass, which makes assembling a multi-document application quick without trusting any of it to a third party.

Applications frequently want a single PDF rather than loose images. The order that keeps the result small is to compress each page to around 200 KB first, then combine them, because compressing after merging gives you far less control over the final size.

A five-page PDF built from 200 KB pages lands near 1 MB — easy to email and quick for a reviewer to open. If the portal accepts images instead, uploading the compressed pages directly avoids the extra step entirely and keeps each file comfortably under its limit. Either way, compressing before the upload is what keeps the whole submission small enough to go through in one attempt.
