How to Combine Multiple Images Into One PDF

Whether it's a multi-page form you photographed with your phone, a set of receipts for an expense report, or scanned pages of a document, the fastest way to make them shareable as one file is combining them into a PDF.

What matters before you start

• Photo order — arrange your images in the order you want the pages to appear before combining, since most tools keep the order you add them in
• Consistent orientation — rotate any sideways photos first, so pages don't appear rotated in the final PDF
• Reasonable lighting and framing — a PDF can't fix a blurry or badly cropped photo, so it's worth a moment to retake anything unreadable

The process

Using Digy's image-to-PDF tool, you add your images in order, and they're combined into a single PDF entirely on your device — nothing is uploaded to a server in the process. This matters more than it might seem for anything containing personal information: ID photos, bank statements, medical documents. The result downloads directly as a normal PDF file, openable anywhere.

A few practical tips

• If a page came out too large as a photo, compress it before combining — this keeps the final PDF a manageable size for email attachments, which often cap around 20-25MB
• For documents you'll need to reference often, name the resulting PDF clearly before saving — combined files are easy to lose track of in a downloads folder
• If you only have one image, there's rarely a reason to convert it to PDF — see our comparison of PDF vs images for when each format actually helps
