How to convert JPG and PNG images to a PDF

Why convert images to PDF?

A PDF is easier to share, print and archive than a folder of loose images. Many forms and portals also accept only PDF uploads. Combining photos of a receipt, pages of a notebook or a set of screenshots into one document keeps everything together and in order.

Step-by-step

  1. Open the Images to PDF tool and add your JPG, PNG or WebP files.
  2. Drag the files into the order you want the pages to appear.
  3. Choose the page size: A4, Letter, or fit to image, which sizes each page to match its picture.
  4. Set the orientation and margin, then convert and download the PDF.

Choosing page size and orientation

  • A4 or Letter suits documents you plan to print. Use A4 in most of the world and Letter in the US and Canada.
  • Fit to image keeps each image at its own proportions with no white borders. It is a good choice for screenshots and for anything you will only view on screen.
  • Automatic orientation switches between portrait and landscape to suit each image, which is useful when a batch mixes both.

Getting good results

  • Start from good source images. A blurry photo stays blurry inside a PDF, and converting does not add detail.
  • Photograph documents in even light, flat and straight-on, to avoid shadows and skewed text.
  • Large photos make large PDFs. If the file is too big to email, resize the images before converting.
  • A PDF made from photos is an image, not searchable text. It will look like a document, but you cannot select or search the words.

Which image format should you start with?

The tool accepts JPG, PNG and WebP images. JPG is the usual format for photographs. It stores photos compactly, but it is lossy, which means some detail is discarded every time the image is saved. PNG is better for screenshots, diagrams and anything with sharp text or flat colours, because it keeps edges crisp. WebP is a newer format that many websites and phones use, and it can be smaller than either.

For a document scan or a photo of text, a clear JPG or PNG both work well. What matters more than the format is the quality of the picture itself.

Taking photos that convert into readable documents

When people photograph a paper document with a phone, the same few problems appear again and again. Fixing them at the source gives a much better PDF than any conversion setting can.

  • Use even light. Avoid a shadow from your hand or phone falling across the page.
  • Hold the camera directly above the page, not at an angle, so the text is not skewed.
  • Fill the frame with the page but keep all four edges visible.
  • Place the paper on a plain, contrasting surface.
  • Check that the text is sharp before you move on. Zoom in on the photo to confirm.

Understanding what the PDF contains

A PDF built from photographs holds pictures of pages, not text. That has two consequences. First, you cannot select or search the words. Second, the file size depends on the size of the images, so a phone photo of several megabytes will produce a large page.

If the PDF needs to be small, resize or crop the images before converting. If it needs to be searchable, the pages need text recognition, which is a separate step this tool does not perform.

Common uses

  • Submitting ID or proof of address to a portal that accepts only PDF files.
  • Combining photos of a handwritten form, a signed page and a supporting document into one submission.
  • Turning screenshots of a conversation or a web page into a single document you can share.
  • Archiving receipts, warranty cards and manuals as one file per purchase.
  • Assembling a simple photo booklet or portfolio for printing.

Frequently asked questions

Can I mix JPG, PNG and WebP in one PDF? Yes. Each image becomes its own page whatever its format.

Will the images be compressed? The tool places your images into the document. It does not deliberately reduce their quality.

What if my photos are sideways? Rotate the finished PDF, or use Organize Pages to fix individual pages.

Are my photos uploaded anywhere? No. The conversion runs in your browser, so your images stay on your device.

Troubleshooting common problems

  • The PDF is far too large: the source photos are probably several megabytes each. Resize them to a sensible size, such as the pixel dimensions you actually need for reading or printing, and convert again.
  • Pages have unwanted white borders: choose the fit to image page size and set the margin to a small value, so each page matches its picture.
  • Images appear stretched or cropped: use automatic orientation so landscape and portrait pictures each get a suitable page, and avoid forcing a fixed shape on mixed images.
  • The text in the picture is hard to read: retake the photo in better light and closer to the page. Conversion cannot recover detail that the photo does not contain.
  • One page is upside down: fix that page afterwards with the Organize Pages tool rather than starting again.
