How it works

Each page is rendered and rebuilt as a JPEG image, and the quality is lowered until the whole file is at most 300 KB. A one- or two-page certificate scan usually stays sharp at that size. For long documents, upload only the pages asked for – extract them first with Extract pages.

Tips

  • Scan in colour at 150–200 DPI; higher DPI only adds bytes.
  • Crop away blank borders before making the PDF with JPG to PDF.
  • If the result is under 50 KB, use the original or a sharper scan.

Frequently asked questions

Which exams need a 50–300 KB PDF?

The NEET UG 2026 bulletin asks for certificates as PDF of 50–300 KB, and the JEE Main 2026 bulletin asks the same for the Class 10 certificate.

What if my PDF is already under 50 KB?

Upload it as it is if the form accepts it, or scan at a higher resolution – compressing will not make a file bigger.

PDF का साइज 300kb कैसे करें?

PDF ऊपर डालें, 300 KB टारगेट पहले से सेट है। Compress PDF दबाएँ और “Meets” दिखने पर डाउनलोड करें।

Is the text still readable?

For one to three pages, yes. Text becomes part of an image, so you cannot select it, but it reads clearly on screen.

Is my PDF uploaded?

No. Compression runs in your browser.
