- ✓Identity Proofs: Front and back of Aadhaar, Voter ID, or Passport can be merged into a neat 2-page PDF document.
- ✓Page Sizing: A4 is the international standard for government applications, ensuring consistent rendering on reviewer screens and printers.

Frequently Asked Questions About Images to PDF Converter
Answers to common queries regarding file limits, quality preservation, and exam portals:
Can I combine both JPG and PNG images into the same PDF?
↓
Yes. Our tool accepts a mixture of JPG, PNG, and WebP images. They are decoded and seamlessly placed onto consecutive pages within the resulting PDF file.
What is the difference between A4 and Original dimensions?
↓
Choosing A4 scales each photo to fit within standard international paper boundaries (210 × 297 mm), ideal for printing. Choosing "Original Image Dimensions" creates a PDF page whose exact width and height match the pixel dimensions of that specific image.
Are my confidential certificates or ID cards uploaded to a server?
↓
No. The entire PDF compilation is performed using the client-side `pdf-lib` library directly in your browser JavaScript memory. Not a single byte of your documents is transmitted over the internet.
How do I keep the resulting PDF file size small?
↓
If your photos were taken with a high-resolution smartphone camera (often 5MB to 10MB per photo), use our Image Compressor to reduce each image to around 200KB to 500KB before merging them into a PDF. This ensures your final PDF remains well below portal file size limits.
