Free tool

Compress a PDF to under 200 KB.

200 KB is the most common document limit on Indian portals: one sharp page, or four or five plain ones. Drop the PDF in, and the tool redraws each page smaller until it's under the limit, then checks it. Nothing is uploaded.

Who asks for 200 KB

What 200 KB looks like

  • One or two pages come out sharp, at 150 DPI or better for typed pages: as good as the original scan to the eye.
  • Four dense pages fit at 85 DPI (193 KB in our test of a four-page form with tables): readable, with the smallest print soft. Five or more typed pages, split.
  • Grey pages shrink colour scans of black-and-white documents without losing anything. Keep colour only if a stamp or seal must show in colour.
  • The check counts 1,000 bytes to the KB, so a passing file passes on a portal that counts 1,024 too.

Every page is redrawn as a JPEG at the sharpest DPI that fits, from 200 down to 72, so the file is only as small as it has to be. The tool tells you the DPI it settled on when it goes below 120.

If it won't go that small

  • Five or more dense pages under 200 KB is under 40 KB a page, which is 72 DPI or won't fit at all. Split into two or three files if the portal lets you, or drop pages the portal didn't ask for.
  • A scan with a dark or textured background costs more than one on white. Rescan in flat light, or photograph on a white sheet.
  • Photos of documents from a phone are often 3,000 pixels wide. That's fine: the tool redraws them anyway, and it's the page's detail, not its pixel count, that sets the size.
  • If the tool says it couldn't get under 200 KB, it tells you the smallest it could make, so you can see how much would need to go.

Photos of documents rather than a PDF? The images-to-PDF tool makes one PDF under the same limits, and an Aadhaar goes through the safe Aadhaar copy tool, which masks the number as well.

Questions

Which is better for a certificate, colour or grey?+
Grey, unless the portal asks for colour. Most certificates are black type on white paper with one stamp; grey keeps the stamp visible and halves the bytes.
Will the pages still be A4?+
Yes. Each page keeps its size on paper; only the dots per inch change, so it prints and views as before.
Does it keep the text selectable?+
No. The pages are redrawn as images, so there is no text layer afterwards. Nothing hidden in the original is left behind either.
Is the PDF uploaded?+
No. It's opened and redrawn in your browser, and the result stays on your device.
