Use Image to PDF when you need to combine document photos into one PDF for email or portal forms.
When to use it
- Combine document photos into one PDF for email or portal forms.
- Prepare phone-scanned pages for IRCC-style, USCIS-style, HealthCare.gov-style, or generic size targets.
- Package receipts and supporting images into a single attachment while checking page order.
How to use it
- Add images in page order.
- Choose output quality and, if needed, a portal file-limit preset.
- Create the PDF and check that every image appears on the expected page.
What to check
- Rotate and crop photos before making the PDF when alignment matters.
- Large image batches can still produce a heavy PDF, even after quality reduction.
- Portal checks help prepare the file but do not guarantee acceptance.
