About Compress PDF

Government forms usually cap uploads at 200 KB or 1 MB. This tool optimises every page and brings the file size down a long way. Scanned copies give the best results, and the black & white option shrinks them further still.

How to compress a PDF — step by step

  1. Upload the PDF you need to shrink.
  2. Pick a level. Balanced suits most uploads; Light keeps more quality; Strong squeezes hardest.
  3. Switch on black & white if the document is text and colour does not matter — it makes a large difference.
  4. Compress, then check the new size against the limit you have to meet.

Why government portals cap uploads

Most Indian application portals limit each upload to somewhere between 200 KB and 2 MB. A phone-scanned document runs to several megabytes because every page is a full-resolution photograph, so the file is refused with a message that does not explain what to do about it.

Compression re-encodes each page at a sensible resolution for reading and printing. A ten-megabyte scan commonly comes down to under one megabyte with the text still perfectly legible.

How much smaller will it get?

Type of PDFTypical reduction
Phone or scanner scans60–90% smaller
Documents with photographs50–80% smaller
Text made from Word or a websiteVery little — sometimes nothing

That last row surprises people. A text-only PDF is already tiny and highly efficient; there is nothing to squeeze. If your file is already small and will not shrink, the tool says so rather than pretending otherwise.

The trade-off you are making

Compression turns pages into images, so text in the compressed file can no longer be selected, searched or copied. For a form upload that is irrelevant — the office only looks at it. For a document you need to search or quote from, keep the original as well.

If the compressed text looks soft, step back to Light. If you still cannot meet the limit, black & white mode usually gets you there, or split the document into parts with Split by File Size.

Frequently asked questions

How much smaller does it get?

Scanned PDFs often drop by 60-90%. Text-only PDFs change much less.

Will the text still be selectable?

No. Compression turns the pages into images, so text cannot be copied. For form uploads that is perfectly fine.

How is the quality?

On the balanced setting the document reads comfortably. Choose 'Light' if you need higher quality.

Is my file uploaded to a server?

No. Compression runs in your browser and the file stays on your device.

Will the text still be selectable afterwards?

No. Pages become images. Keep your original if you need searchable text.

My file barely shrank. Why?

It is almost certainly a text PDF rather than a scan, and text PDFs are already small. There is genuinely nothing to remove.

Can I compress to an exact KB figure?

Not exactly — pick a level and check the result. For a hard limit on a single image, Image Resize targets an exact KB.

Is the quality good enough to print?

On Balanced, yes for ordinary documents. Use Light for anything with fine detail.
