How to Convert JPG, PNG Images to PDF Online for Free
Need to send a photo as a PDF? Want to combine multiple screenshots into a single document? Converting images to PDF is a common task — and you can do it for free online in seconds, without installing any software.
Why Convert Images to PDF?
There are many situations where PDF is better than a raw image file:
- Professional documents — PDFs look more formal than JPGs when submitting applications or reports
- Combine multiple images — merge several photos or screenshots into one neat file
- Preserve quality — PDFs don't lose quality when shared or printed
- Universal compatibility — PDFs open correctly on any device or operating system
- Smaller file size — PDF compression can make images smaller without visible quality loss

| PNG | Screenshots, graphics with transparency | ✅ Yes |
| WEBP | Modern web images | ✅ Yes |

How to Convert an Image to PDF Online
Follow these simple steps to turn any image into a PDF file:
- Go to our free PDF Tools page
- Select "Image to PDF" from the tool list
- Upload your image(s) — drag and drop or click to browse
- Arrange the order if you uploaded multiple images
- Choose page size (A4, Letter, or fit to image)
- Click "Convert" and download your PDF
How to Combine Multiple Images Into One PDF
If you have several photos or screenshots you want in a single PDF document:
- Open the Image to PDF tool
- Upload all your images at once (or one by one)
- Drag to reorder the pages as needed
- Click "Convert to PDF"
All images will be combined into a single PDF, one image per page — perfect for reports, portfolios, or collections of receipts.
💡 Pro Tip: If your PNG has a transparent background, the PDF will show a white background by default. This is normal — PDFs don't support transparency the same way PNG does.
Tips for Best Results
- Use high-resolution images — at least 150 DPI for screen, 300 DPI for print
- Choose the right page size — "Fit to image" preserves the original dimensions exactly
- JPG for photos — use JPG source files for smaller output PDFs
- PNG for screenshots — PNG preserves text and UI elements more clearly
Is My Image Safe?
Yes. Your images are processed entirely in memory and never stored on our servers. Files are deleted immediately after the PDF is generated. We do not access, share, or analyze your images.
Common Use Cases: When to Convert Images to PDF
Converting images to PDF solves a wide range of everyday problems:
- Submitting documents online — Job applications, visa forms, and university portals often require PDF. A phone photo of your ID or certificate can be converted in seconds.
- Sending invoices or receipts — A photo of a handwritten receipt or paper invoice looks far more professional when converted to PDF.
- Creating a portfolio — Designers and photographers can combine multiple JPGs into a single multi-page PDF to share with clients.
- Archiving printed documents — Photograph paper records and convert to PDF for long-term digital storage.
- Sharing screenshots as a report — Multiple screenshots are easier to share as a single PDF than as separate image files.
How to Adjust Page Size When Converting
When you convert an image to PDF, the page size can be set to standard paper sizes for professional results:
- A4 (210×297mm) — Standard in most countries, ideal for official documents and letters
- Letter (8.5×11 inch) — Standard in the United States and Canada
- Fit to image — PDF page matches the exact dimensions of your image, with no white border
For documents you plan to print or submit officially, use A4 or Letter. For archiving photos or screenshots, "Fit to image" is usually the best choice.

Frequently Asked Questions
Does converting an image to PDF reduce quality?
No. Our converter embeds the image at its original resolution. The PDF looks identical to the source image. Quality only changes if you separately run PDF compression afterward.
Can I convert a screenshot to PDF?
Yes. Screenshots are PNG or JPEG files and convert to PDF perfectly. This is especially useful for sharing app errors, mockups, or web captures as a professional document.
How many images can I combine into one PDF?
Our tool supports multiple image uploads in one conversion — each image becomes a separate page in the final PDF. There is no fixed limit on the number of images.
