Convert JPG to PDF

How to Convert JPG to PDF

1

Add your images

Click “Select images” or drag and drop JPG, PNG, or WebP files into the upload area. You can add up to 50 images at once.

2

Reorder and adjust

Drag images to reorder them. Set page size (A4 or Letter) and orientation. Each image becomes one PDF page.

3

Convert and download

Click “Convert to PDF”. The combined file saves to your Downloads — original images stay on your device.

Every step runs in your browser. No server uploads, no waiting.

Why use this tool

DukPdf’s JPG to PDF tool converts one or more images into a single PDF document directly inside your browser. Drop in a stack of photos, scans, or screenshots and get a clean, shareable PDF in seconds — no server uploads, no watermark on the output. If you need to go the other direction, use PDF to JPG to extract pages as images. To shrink the result for an email attachment, run it through Compress PDF afterwards. For a step-by-step guide, see our JPG to PDF guide.

JPG to PDF — questions

What image formats are supported?

JPG, JPEG, PNG, and WebP. HEIC and other formats can be converted to JPG first using any standard image converter.

Can I convert multiple images into one PDF?

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

Will the image quality be preserved?

Yes. Images are embedded into the PDF at their original resolution. If you need a smaller file, use Compress PDF afterwards.

What page size will the PDF use?

A4 by default, with the option to switch to US Letter. Each image is fitted to the page with its original aspect ratio preserved.

Are my images uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly. Open DevTools → Network tab while converting — you’ll see zero upload requests carrying your images.

Can I set a custom filename for the output PDF?

Yes. The tool lets you name the output file before downloading, so you don’t end up with a folder of “merged-1234.pdf” files.
