Complete Guide to Converting Images to PDF
When and how to convert images to PDF. Supported formats, page layout, file size tips, and batch conversion best practices.
When PDF makes sense
Use PDF when you have multiple images to present in order, need consistent layout, or want reliable printing across devices.
Supported formats
Typical sources include JPEG, PNG, HEIC/HEIF, and screenshots. Converting once to PDF reduces the chance of repeated quality loss.
Page size and orientation
Choose page size (Letter, A4) and orientation to match your content. Rotate pages so photos read naturally top‑to‑bottom.
Margins and bleed
Add modest margins for printing, and avoid excessive cropping. Keep important content away from page edges.
Batch conversion best practices
Upload all images, reorder thumbnails, and delete duplicates before exporting. Name the final PDF clearly for sharing.
File size tips
Use efficient formats or compression at conversion time rather than recompressing later. For email, keep PDFs under common size limits (e.g., 20–25 MB).
