A common scenario

You have a stack of receipt photos on your phone and need to send a single PDF to your accountant instead of 12 image attachments.

Why privacy matters here

Most JPG-to-PDF converters upload your images to a remote server. DukPdf converts locally in your browser, so the photos never leave your device. See how local processing works.

Convert JPG to PDF — questions

Can I convert multiple JPGs into one PDF?

Yes. Drop in up to 50 images and they will be merged into a single PDF in the order you choose. Drag thumbnails to reorder before downloading.

What image formats are supported?

JPG, JPEG, PNG, and WebP. HEIC files from iPhones can be converted to JPG with any standard image converter first, then dropped into the tool.

Will image quality be preserved?

Yes. Images are embedded into the PDF at their original resolution. Use Compress PDF afterwards if the file is too large to email.

Are the images uploaded?

No. The conversion runs in your browser using WebAssembly. Open DevTools → Network tab and you will see zero upload requests while converting.
