When you need a 500 KB PDF
Exam, scholarship and university admission portals often limit documents like caste certificates, income certificates and mark sheets to 500 KB. That's enough for a few clear pages if the PDF is compressed well.
Tips
- For text documents, turn on Black and white for a smaller, sharper result.
- If you're starting from photos of paper, use Scan document first so the pages are straight and clean.
