PDF Ready

300 KB is strict

Compress a PDF to 300 KB on Android

300 KB is an unusually tight PDF target. Use it only when the upload path really requires it, then inspect the prepared copy carefully before clean export.

When 300 KB makes sense

  • Some passport or visa upload paths set very small PDF limits.
  • A short, clean scan or a simple passport bio page has a better chance than a photo-heavy multi-page document.
  • If the portal allows 500 KB, 1 MB, or 2 MB, use the larger limit to preserve readability.

What to inspect before export

  • Zoom into passport numbers, dates, seals, signatures, and small print.
  • Check that compression did not turn text into blocks or make photos unusable.
  • If the copy is not readable, rescan cleaner or choose a larger allowed target.

How PDF Ready helps

  • Pick 300 KB directly from the size selector.
  • Prepare locally and review the result before paying for the final clean export.
  • Keep the original in Originals while testing another target if needed.

Common 300 KB failure cases

  • Screenshots and dark photos often compress poorly.
  • Dense certificates, multi-page records, and large scans may need more room.
  • OCR and PDF/A-2b can make the target harder, so enable them only when required.

Before you accept a 300 KB result

  • Read the smallest text on the page at normal phone zoom and again zoomed in.
  • Check whether the page became grayscale, blurry, or blocky in places where the destination needs detail.
  • If the source contains several pages, consider whether the destination actually expects a single combined PDF.
  • Use the 300 KB copy only when it satisfies both the file-size rule and the readability rule.

FAQ

Common questions

Can every PDF be compressed to 300 KB?

No. Some files can technically fit but become unreadable. Review the result and use a larger allowed target when needed.

Should I rescan or compress harder?

If the scan is dark, tilted, or photo-heavy, a cleaner scan usually helps more than pushing compression harder.

Is 300 KB mainly for India e-Visa?

It can be used for any real 300 KB upload limit. For India e-Visa, confirm that the specific document type uses the 10 KB to 300 KB PDF rule.
