Whether you're scanning documents with your phone or compiling a photo collection, converting images to PDF is one of the most common digital tasks. Here's how to do it in seconds.

Why Convert Images to PDF?

Converting JPG or PNG images to PDF has several practical advantages:

• Single file for multiple images — combine 10 photos into one organized PDF
• Universal format — PDFs open on every device without special software
• Professional appearance — PDFs look cleaner than loose image files
• Easy to email — one attachment instead of multiple image files
• Print-ready — PDFs are the preferred format for printing services

Tips for Best Results

Upload in the right order. If you're combining multiple images, arrange them in the correct sequence before converting. ModifyPDF lets you drag and reorder.

Use high-resolution images. The quality of your PDF depends on the quality of your source images. Higher resolution images produce sharper PDFs.

Compress after converting. If the resulting PDF is large, use the Compress PDF tool to reduce the file size.

Common Use Cases

ID documents: Combine front and back scans of an ID into a single PDF.

Portfolios: Compile design work, artwork, or photography into a professional PDF portfolio.

JPG vs PNG — Which Should You Use as Input?
