JPG to PDF Converter

A PDF keeps a set of images together, in order, in one file that looks the same on every phone and computer. That’s why so many forms and inboxes ask for one. Common reasons to convert:

• Documents you’ve photographed: receipts, ID, signed forms, bank statements and handwritten notes.
• Applications and portals for jobs, visas, universities and insurance claims that only accept PDF uploads.
• One attachment instead of ten: send a set of photos as a single file that opens in order.
• Printing: page size and margins are fixed, so what you see is what prints.

The defaults (A4, automatic orientation, Contain, 20 pt margin) suit most documents. Here’s what each setting does:

Your images don’t lose quality. JPG and PNG files go into the PDF exactly as they are, without being compressed again, so every page looks identical to the original. Other formats (WebP, AVIF, GIF and BMP) are converted to high-quality JPEG on the way in. Phone photos that are stored sideways with a rotation tag are turned upright, so nothing comes out on its side.

The flip side is that the PDF is roughly as big as all your images added together. Ten 4 MB phone photos make a PDF of about 40 MB, which is too big for many email services and upload forms. To make it smaller:

• Compress the images first. Phone photos often shrink by more than half with no difference you can see.
• Resize them to about 2,500 pixels on the longest side. That’s still over 200 dpi on an A4 page, so text stays sharp when printed.
• Then add the smaller copies here and create the PDF again.

iPhones save photos as HEIC, which many websites won’t accept. You can add HEIC files here directly: they’re converted to JPG on your device, then placed in the PDF like any other image. If you only need JPG copies of the photos, use the HEIC to JPG converter instead.

Most PDFs made from photos are documents. A few habits make them far easier to read:

• Lay the page on a plain, dark surface in daylight, and turn the flash off to avoid glare.
• Hold the phone directly above the page, parallel to it, so the text isn’t skewed.
• Crop away the table around the page before converting.
• If the text looks faint, raise the contrast with Adjust Image Colors.

Most online converters upload your files to their servers to process them. This one doesn’t. The PDF is built by your browser, on your own phone or computer, so your images and the finished PDF are never sent anywhere. That matters when the images are passports, payslips or medical letters.

You can check this yourself: open your browser’s developer tools, watch the Network tab and create a PDF. The only requests are anonymous page-view counts, described in our privacy policy. After your first visit, the converter works offline too.
