PDF DocOfficeHow to Convert Images (JPG, PNG) into a Single PDF
Photographed receipts, scanned certificates and screenshots are much easier to share when they are collected in one PDF. The recipient opens a single file instead of a dozen attachments.
The Image to PDF tool builds the document in your browser. You choose the order of the images and the margins, and the PDF is created on your device.
How it works
Images and PDFs behave differently. A photo is just pixels, while a PDF page can hold many images together with page size, margins and order. Combining pictures into a PDF gives you a single, predictable file that prints at a known size and opens the same way on every device, which is why institutions often prefer it for supporting documents.
When this is useful
- Submitting scanned certificates and ID documents online.
- Making a single file from photos of a handwritten note or whiteboard.
- Bundling product photos or portfolio pages for a client.
- Sending receipts for reimbursement.
- Creating a quick PDF from screenshots for a bug report.
Step-by-step instructions
- Open the Image to PDF tool and add your images (JPG, PNG, WebP or BMP).
- Drag them into the order you want them to appear.
- Choose margins if you like, then press convert.
- Download the PDF and check that each image is the right way up.
Tips for the best results
- Rotate photos before conversion if they were taken sideways.
- Crop the edges of scans so that the page looks clean.
- Large phone photos create heavy PDFs. Use the Compress PDF tool afterwards.
- Use consistent image sizes for a neat result.
- If you need editable text rather than pictures, use the Image to Excel & Word tool.
Common problems and how to fix them
Pictures are upside down or sideways
Rotate them in your photo app before conversion, then upload them again.
The PDF is too heavy to email
Run it through Compress PDF, or resize the photos before converting them.
Margins look uneven
Use consistent image sizes and set the same margin for every page.

How many images can I add?
As many as your device can handle comfortably, usually dozens.
Does it change image quality?
Images are embedded at their original quality. Compress afterwards if you need a smaller file.
Are my pictures uploaded?
No. Conversion runs in your browser.
