JPG to PDF converter
TL;DR: add photos or scans, drag them into the right order, choose A4, Letter or the image size and download one PDF. Everything happens in your browser, so the images are never uploaded.

A PDF is the easiest way to send several photos, receipts or scanned pages as one document: it opens the same way on any phone or computer, keeps the page order and is accepted by every online form that asks for “one file”. This tool puts each image on its own page and gives you a single PDF in a few seconds.
How to use it
- Add images. Drag up to 100 JPG, PNG, WebP, GIF or BMP files onto the box, choose them with the button or paste a copied image with Ctrl+V.
- Set the order. Drag the rows or use the arrows. The first image becomes the first page.
- Choose the page layout. A4 or Letter with automatic orientation suits documents and scans; “Same as image” makes each page exactly the size of its picture. Add margins if the PDF will be printed.
- Create and download. Press “Create PDF” and save the file.
A4, Letter or the image size?
| Page size | Dimensions | When to use |
|---|---|---|
| A4 | 210 × 297 mm | Documents for Europe, Asia and most of the world, scans for official forms |
| Letter | 8.5 × 11 in (216 × 279 mm) | Documents for the US and Canada |
| Same as image | Page = picture | Photo albums, screenshots, slides: no white bars around the image |
On A4 and Letter each image is scaled to fit inside the margins and centred; small images are not stretched beyond their natural size, so they stay sharp. With automatic orientation a wide photo gets a landscape page and a tall one gets a portrait page.
JPG files go into the PDF as they are, without being compressed again, so the photo quality does not drop. PNG keeps its transparency; WebP, GIF and BMP are converted on the fly, because PDF cannot store those formats directly.
At YuSMP Group we build websites and keep them fast, and heavy images and PDFs are the most common reason pages load slowly. If documents and images need optimising across a whole site, see our web development service or start with the page speed test.
FAQ
How do I convert JPG to PDF?
Add the images with drag and drop, the button or Ctrl+V, set the order, choose the page size and press “Create PDF”. The file is ready in a few seconds and is downloaded straight from your browser.
Are my images uploaded to a server?
No. The PDF is built in your browser with the open-source pdf-lib library. The images stay on your device and are not sent anywhere.
Can I combine several JPG files into one PDF?
Yes, up to 100 images at once. Each image gets its own page, in the order shown in the list. Drag the rows or use the arrows to change it.
Does the converter reduce photo quality?
No for JPG: the original file is placed into the PDF without recompression. PNG keeps its pixels and transparency. Only WebP, GIF and BMP are re-encoded, at high quality, because PDF does not support them natively.
Which page size should I choose?
A4 for most countries and official forms, Letter for the US and Canada. “Same as image” is best for photo albums and screenshots, because there are no white bars around the picture.
Why is my phone photo rotated correctly in the PDF?
Phones store the rotation in the photo’s EXIF data. The tool reads it and turns the image the way you see it in your gallery before placing it on the page.
Can I make a PDF from scans on my phone?
Yes. The page works in mobile Safari and Chrome: choose photos from the gallery, set the order and download the PDF. For long scanned documents A4 with small margins is a good default.
Is there a file size limit?
Each image can be up to 50 MB and up to 100 images per PDF. The real limit is your device’s memory: very large batches are faster on a computer.
