Why convert JPG to PDF?
Many forms, schools, employers and government portals accept documents only as PDF. If you photographed a receipt, ID page or signed form with your phone, you have JPGs.
This tool places each JPG on its own page and, if you like, merges them into a single PDF in the order you added them. Nothing is uploaded, which matters for personal documents.

Frequently asked questions
How do I combine several JPGs into one PDF?
Keep “Merge into one PDF” switched on, add all the images, and download the single PDF. Turn it off to get one PDF per image.
Is it safe to convert ID cards or documents here?

Will the image quality drop in the PDF?
Images are embedded at their full resolution with high JPG quality, so text in scans stays readable.
Which page size should I choose?
“Fit to image” makes each page exactly the size of the photo. Choose A4 (most countries) or Letter (US and Canada) if the PDF will be printed or must match a standard size.
