  1. Lossless first

    We rebuild the PDF's internal structure. If that's enough, the text stays selectable.

  2. If not, exact size

    We turn each page into an image and find the highest resolution and quality that fit your limit.

  3. Download and done

    You see the final size against the limit and a preview before saving.

Everything runs in your browser. Your document is never uploaded to any server.

Where is a PDF under 300 KB required?

A 300 KB limit is common on:

  • Government, tax and immigration portals.
  • University enrolment and visa applications.
  • HR, payroll and recruitment platforms.
  • Invoices and receipts on expense tools.

At this size most documents with a few pages fit at 100 to 150 dpi, a resolution that still prints well.

Private by design

Most online tools upload your files to their servers. Not here: everything is processed in your own browser and nothing is ever sent anywhere. That's why you can safely use it with your ID, passport, payslips, medical reports or contracts.

Tip

Before scanning, use black and white or greyscale if the document has no photos: it takes less space and reads just as well.

Frequently asked questions

Are my files uploaded to a server?

No. Everything is processed inside your browser. Your files never leave your device.

Is it free?

Yes. No sign-up, no watermark and no usage limits.

How do I get my PDF under 300 KB?

Choose the file, keep 300 KB as the maximum size and click Compress. Lossless compression is tried first; if that's not enough, the best resolution and quality that fit are found.

Will the text still be selectable?

If lossless compression is enough, yes. If the file has to shrink further, pages are turned into images and the text is no longer selectable, although it reads exactly the same.

What if it can't reach the size?

It means the document would become unreadable at that size. Split the PDF into several parts or check whether the form accepts more than one file.

Is 1 MB 1,000 or 1,024 KB?

Here 1 MB = 1,024 KB. Some portals count 1,000. If you're close to the limit, pick a slightly smaller one to be safe.
