Compress PDF to 200KB Online — Free & Private

Reduce a scanned certificate, ID or supporting document to 200KB or under for visa, immigration, job and university portals. Honest compression, done entirely in your browser — your PDF is never uploaded.

How to compress a PDF to 200KB

1. Upload your PDF above. The tool reads it locally and shows the original size and page count.
2. Press Compress PDF to 200KB. Each page is rendered in your browser and rebuilt as an efficiently compressed page image.
3. The tool automatically tries higher quality first, then steps resolution and quality down until the rebuilt PDF fits 200KB — keeping the best quality that fits.
4. Compare the original and compressed sizes, then download the new PDF and upload it to your portal.

The complete guide to compressing a PDF under 200KB

Government recruitment systems, university admission portals, state licensing platforms and international visa and immigration services frequently require document attachments of 200KB or less — a scanned degree certificate, a passport copy, a bank statement. A single page scanned at a copy shop can be 1–3MB on its own, so a five-page document can exceed the limit by fifty times. This compressor closes that gap without asking you to hand a sensitive document to a stranger's server.

How the compression actually works. Most oversized PDFs are oversized for one simple reason: inside, each page is a very high-resolution photograph. This tool opens the PDF in your browser with the PDF.js library, draws every page onto a canvas at a controlled resolution, and rebuilds a fresh PDF with the jsPDF library using JPEG compression tuned page by page. It starts with generous settings — roughly print-quality resolution — and if the rebuilt file is still over 200KB, it steps the resolution and quality down and rebuilds again, as many times as needed. You receive the first version that fits the limit, which is by definition the best-looking version that fits.

What compresses well, and what does not — honestly. Scanned documents compress best of all: certificates, ID cards, transcripts, signed forms. These routinely shrink by 90% or more and stay perfectly readable. Two honest caveats follow from the method. First, because pages are rebuilt as images, text in the result looks the same on screen and in print but is no longer selectable or searchable — portals that only display or print your evidence will not care, but you should keep your original if you need an editable copy. Second, physics sets a floor: a 40-page full-color document cannot always reach 200KB and remain legible. When that happens, this tool still gives you its smallest result and says so plainly, rather than pretending the file passed.

If your document will not fit, do this. Split it: most portals ask for specific documents separately anyway, so upload the degree, transcript and ID as individual files instead of one bundle. Remove blank and duplicate pages. And if you are scanning the document yourself, choose grayscale at 150–200 DPI — color at 300 DPI is the single most common cause of multi-megabyte scans, and no official needs a birth certificate in photographic color depth.

Your documents stay yours. A PDF you attach to a visa or job application can contain your passport number, address, qualifications and financial history. Conventional online compressors require an upload, process the file on their servers, and ask you to trust their deletion policy. Here there is nothing to trust: the file is read by JavaScript running in your own browser tab, processed in memory, and gone when you close the tab. The only downloads this page makes are the standard PDF.js and jsPDF code libraries from a public CDN — your document itself is never transmitted anywhere.
