Best for

  • Scanned marks card PDF
  • Caste / income certificate PDF
  • Hostel application document PDF
  • Scholarship document PDF upload

Important note

  • Text-only PDFs may already be small.
  • Maximum compression may reduce clarity.
  • Output may not keep selectable text.
  • Always verify final document before uploading.

Which Compression Option Should You Choose?

Use the correct option based on the portal upload limit. Very high compression can reduce clarity, so verify the final file before submission.

🎯
For 500KB upload limit

Select Try 500KB. This is usually better for one or two scanned certificate pages.

📉
For 200KB / 100KB limit

Select Maximum and grayscale. It may reduce clarity, so use it only when the portal rejects bigger files.

👁️
For readable documents

Select Balanced or High Quality for marks cards, certificates and reports where text clarity is important.

Tip: If the file is already a text-based PDF, use Image to PDF only when required. This compressor is mainly useful for scanned PDF and image-heavy PDF files.

PDF Size ಕಡಿಮೆ ಮಾಡುವ ಕನ್ನಡ ಮಾರ್ಗದರ್ಶಿ

SSP Scholarship, NSP Scholarship, Hostel Application ಅಥವಾ Government Application ನಲ್ಲಿ PDF file size limit ಇರುತ್ತದೆ. Marks card, caste certificate, income certificate, study certificate, Aadhaar copy ಮುಂತಾದ scanned PDF documents ಗಾತ್ರ ಹೆಚ್ಚು ಇದ್ದರೆ ಈ tool ಬಳಸಿ file size ಕಡಿಮೆ ಮಾಡಬಹುದು.

Upload ಮಾಡುವ ಮೊದಲು compressed PDF ಅನ್ನು ಒಮ್ಮೆ open ಮಾಡಿ clarity ಸರಿಯಿದೆಯೇ ಎಂದು check ಮಾಡಿ. Text ಸ್ಪಷ್ಟವಾಗಿ ಕಾಣದಿದ್ದರೆ Balanced ಅಥವಾ High Quality option ಬಳಸಿ ಮತ್ತೆ compress ಮಾಡಿ.

500KB limit ಇದ್ದರೆ Try 500KB option ಬಳಸಿ. ಸಾಮಾನ್ಯವಾಗಿ ಒಂದು ಅಥವಾ ಎರಡು certificate pages ಗೆ ಇದು useful.
200KB / 100KB limit ಇದ್ದರೆ Maximum + Grayscale option ಬಳಸಿ. ಆದರೆ clarity ಕಡಿಮೆಯಾಗಬಹುದು, ಆದ್ದರಿಂದ final PDF check ಮಾಡಬೇಕು.
Portal upload before final submit Official portal ನಲ್ಲಿ file type, size limit ಮತ್ತು clarity requirement verify ಮಾಡಿ.

Compress PDF FAQ

Common questions about PDF compressor, file size and student document upload.

Can I compress PDF to 100KB?

You can try the 100KB target option, but exact size is not guaranteed. A one-page scanned PDF may reduce close to target, but multi-page files may remain larger.

Is this useful for SSP scholarship?

Yes. This tool is useful for SSP scholarship, NSP scholarship, hostel admission, marks card PDF, certificate PDF and other student document uploads.

Are my files safe?

The PDF is processed inside your browser. Mahiti Sindhu does not upload or store your file. Still, verify the document before submitting to any official portal.

Why did the PDF quality reduce?

Compression reduces file size by optimizing PDF pages as images. Maximum compression creates smaller files but may reduce clarity.

Why is my PDF not reducing?

Text-only PDFs are often already optimized. This compressor works best on scanned PDFs and image-heavy certificate files.

Will the output keep selectable text?

No guarantee. This browser compressor converts PDF pages into optimized images, so text may not remain selectable in the final PDF.
