"Image to PDF for document upload India" is a high-intent search for a reason: recruitment and gov portals often accept PDF only, with strict size caps.
Prep before you convert
- Crop black borders; one doc per file unless the portal asks for a pack.
- 150 DPI is usually enough for screen verification; 300 DPI balloons size.
- Grayscale when colour is not required.
Convert -> check -> compress
- Convert images to PDF locally.
- Zoom 100% and check signature / stamp readability.
- Compress only after the text still looks fine.
