How to Convert JPG to PDF: Combine Multiple Photos Into One PDF (Free)

You photographed every page of a form, an agreement or your marksheets with your phone, and now the portal wants one PDF. Sending ten separate JPGs isn't an option. This guide shows how to convert JPG to PDF and combine all the photos into a single file, in exactly the right page order, free and on any device.

Convert JPG to PDF in 4 steps

1. Open the free JPG to PDF converter.
2. Tap Choose images and select all the photos you want in the PDF, or drag them onto the page.
3. Check the order. Use the ↑ and ↓ arrows, or drag a row, so page 1 is at the top. Remove a wrong photo with ×.
4. Tap Convert to PDF, then Download PDF.

Each photo becomes one page, in the order shown in the list. The file downloads as converted-images.pdf; rename it to something clear, such as Rental-agreement-signed.pdf, before you send it.

Getting the page order right

The number before each file (1, 2, 3…) is its page number in the PDF. Photos are listed in the order you select them, which isn't always the order of the document, so check the list before converting:

• ↑ and ↓ move a photo one place up or down; they work well on a phone.
• Drag a row to move it further in one go on a computer.
• Choose images again adds more photos to the end of the list.
• Clear empties the list so you can start over.

Phone cameras name photos by date and time (for example IMG_20261031_101.jpg), so if you photograph the pages in order, picking them in name order usually gives the right sequence straight away.

When you'll need a single PDF

Whatever the use, a single, well-ordered PDF looks more professional than a pile of loose photos, and reviewers can read it on any phone or computer without extra apps.

Take photos that make a clean PDF

The PDF looks exactly like your photos, so a few seconds of care when taking them makes a big difference:

• Lay the page flat on a dark, plain surface and shoot from directly above, not at an angle.
• Use daylight or bright, even light, and avoid your own shadow over the page.
• Fill the frame with the page. If there is table or floor around it, trim it first with Crop Image.
• Hold steady and check each photo is sharp before moving to the next page. Zoom in on small print.
• Turn sideways photos upright before converting, with Rotate Image.

Page size, quality and file size

Phone photos are often several MB each, so a 10-page PDF can easily run to tens of MB, too big for many upload forms. Two ways to make it smaller:

1. After converting: run the PDF through Compress PDF. Photo-based PDFs shrink a lot; see our guide on compressing a PDF to under 1 MB or 100 KB.
2. Before converting: compress each photo to a set size with Compress Image, then convert. This gives you the most control when a portal sets a strict limit.

PNG, WebP, HEIC and existing PDFs

• JPG to PDF only accepts JPG/JPEG files. For a mix of JPG, PNG and WebP images, use Image to PDF instead; it works the same way.
• iPhone photos in HEIC format need converting first with HEIC to JPG. See our HEIC to JPG guide.
• Need to add the photos to an existing PDF? Convert the photos to a PDF first, then combine both files with Merge PDF. Our guide on merging PDF files into one explains the order and the steps.
• Need to reorder or rotate pages afterwards? Use Organize PDF.

If something goes wrong

• A file is skipped. JPG to PDF accepts only JPG/JPEG. Use Image to PDF for PNG and WebP, or HEIC to JPG for iPhone photos.
• The pages are in the wrong order. Clear the list or move rows with the arrows, then convert again. It only takes a few seconds.
• A page appears sideways. Rotate that photo first, or fix the finished PDF with Organize PDF.
• The PDF is too big to upload. Compress it with Compress PDF, or compress the photos before converting.
• It's slow on a phone with many photos. The work happens on your device, so convert in smaller batches and merge the PDFs afterwards.
