Frequently Asked Questions
1. How do I combine multiple JPG or PNG photos into a single PDF file?
Drop all of your photos into the converter above, arrange their sequence using the ↑ and ↓ buttons, and click "Download Merged PDF".
2. Are my scanned IDs, tax receipts, or signed contracts uploaded to a server?
No. The multi-page PDF 1.4 binary container is assembled 100% locally in your browser RAM. Your private documents never leave your phone or computer.
3. How can I change the order of pages before downloading the PDF?
When two or more images are loaded, each row in the file queue displays ↑ (Move Up) and ↓ (Move Down) buttons so you can reorder pages in one click.
4. What is the difference between A4, US Letter, and "Fit Page to Image"?
A4 and US Letter format every page to standard office paper dimensions so the document prints cleanly. "Fit Page to Image" sizes each PDF page to match the exact aspect ratio of the photo with zero white borders.
5. How does "Auto" page orientation work?
In Auto mode, portrait photos are placed on vertical pages and wide landscape photos are automatically rotated onto landscape pages so images appear as large as possible.
6. Can I convert PNG images with transparent backgrounds to PDF?
Yes. Transparent PNG areas are automatically composited onto a clean white PDF page background so dark text and signatures remain crisp.
7. Can I combine iPhone HEIC photos into a PDF too?
Yes! You can drop .heic files directly (or use /tools/heic-to-pdf) to merge iPhone photos into one PDF.
8. Is there a limit on how many photos I can merge into one PDF?
There are no artificial paywall limits; you can combine up to 100 photos into a single PDF right in your browser.
9. Does Vexolora add any watermarks or page footers to the PDF?
Never. Every page of your generated PDF is 100% clean and watermark-free.
