JPG से PDF बनाएं — फ्री

Converting images to PDF solves a specific problem: most formal document submission systems accept PDF but not raw image files. A scanned bank statement photographed with your phone produces a JPEG. Your university transcript is a photo of a paper document. Your ID card is two JPEGs (front and back). Converting these to PDF makes them acceptable for submission to portals that expect PDF documents.

Why do government portals and institutions prefer PDF? PDF provides consistent rendering across all devices and operating systems — a PDF looks identical whether opened on Windows, macOS, iOS, or Android. Image files (JPEG, PNG) can display differently based on color profiles, screen calibration, and viewing software. PDF also signals document finality — it's harder to casually edit than an image, which matters for submitted evidence and formal documents.

The most common use case is multi-image to single PDF: combining a front and back photo of an ID card, or multiple pages of a scanned document, into a single PDF file that can be submitted as one attachment. Portals that require "scan of ID card" expect a single PDF, not two separate JPEGs.

Image quality in the resulting PDF is crucial. FileCurve inserts images at their original resolution, so the output PDF quality is limited by your original photo quality. For legible document scans, ensure your source image is at least 150 DPI — for an A4 page, that's 1240×1754 pixels minimum. Phone cameras at full resolution typically produce more than enough pixel density for document PDFs.

File size of the resulting PDF depends on image size and compression. An A4 scan at 300 DPI produces a JPEG of about 2–5MB; the resulting PDF wrapping that JPEG will be a similar size. If you need a smaller PDF, compress the JPEG first, then convert to PDF.
