How to use Images to PDF
- Choose the images you want to include and select them in the order you want them to appear.
- Open PDFLeo’s Images to PDF tool and add the selected files.
- Create the PDF, then open the downloaded file to review every page.
- If a page is sideways or cropped, adjust the source image and create the PDF again.
Best practices for reliable results
- Keep an untouched backup of the source document.
- Use a file you have permission to process and share.
- Review every page of the output, not just the first page.
- Check text, page order, links, forms and images where relevant.
- For important work, compare the output with the original before sending it to anyone.
Limitations to know
Large photos can make a large PDF. Image dimensions, aspect ratios and orientation affect the result; inspect the output before sending it.
Frequently asked questions
Can I combine multiple pictures?
Yes, supported image files can be placed into one document. Will the PDF be small? Not necessarily—high-resolution photos can increase file size.
Should I delete the original after conversion?
No. Keep the original until you have checked the result and confirmed it contains everything you need.
