How to Convert JPG to PDF (and Combine Images Into One PDF)
6 min read • Updated October 2026
QUICK ANSWER
Drop your JPG, PNG or WebP images into a JPG to PDF converter, put them in order, choose A4, Letter or fit-to-image and press Convert. You get one PDF with one image per page. Clipaist embeds JPGs without recompression and never uploads them.
Forms, applications and homework often ask for "one PDF", but what you have is a handful of phone photos. Converting images to PDF takes a minute when the tool handles page size, order and rotation for you.
Here is how to get a clean, correctly sized PDF without losing quality.
How to do it, step by step
- Add images. Open JPG to PDF and drop your images (up to 100).
- Order them. Move images up or down. One image becomes one page.
- Choose page setup. Pick A4, Letter or fit to image, orientation and a margin.
- Convert and download. Press Convert to PDF and download the result.
A4, Letter or fit to image?
A4 and US Letter put each image on a standard page, centred, with an optional margin. Choose A4 for most of the world and Letter for the US and Canada. "Fit to image" makes every page exactly as big as its picture, with no white borders, which suits screenshots and designs.
Orientation can stay on Auto: wide images get a landscape page, tall images a portrait page.
Keeping quality
JPG and PNG files are embedded exactly as they are, so there is no recompression and no quality loss. Other formats such as WebP are converted once at high quality. If the PDF turns out too large, run it through the PDF compressor.
Phone photos that come out sideways
Phones save photos in the sensor orientation and add a rotation tag. PDF viewers ignore that tag, so the picture appears sideways. The converter reads the tag and redraws such images upright before adding them, so you do not have to rotate them by hand.
Scanning documents with a phone
Shoot in good light, keep the page flat and fill the frame. Then convert the photos in order, one page per image. For text-heavy scans, A4 with a small margin gives the cleanest result.
QUICK TIPS
- ✓ Name photos in order before adding them.
- ✓ Use fit to image for screenshots.
- ✓ Use A4 with a small margin for scanned documents.
- ✓ Compress the PDF if the result is too big to email.
