Whether you need to send a photo as a PDF, combine multiple images into one document, or turn a phone photo of a form into a submittable PDF — this guide covers every method.
How to Convert a Single JPG to PDF
Open the Image to PDF converter. Go to convertfloor.com/tools/image-to-pdf in any browser.
Upload your JPG. Click the upload area or drag and drop your image. JPG, JPEG, and PNG files are all accepted.
Adjust settings if needed. Choose page orientation (portrait or landscape) and page size (A4 or US Letter) if the defaults do not suit your image.
Click Convert. Conversion is instant for single images.
Download your PDF. Click the download button. The PDF opens in any PDF viewer.
The resulting PDF will have exactly one page — your image fills the page at high quality.
How to Combine Multiple JPGs into One PDF
If you have several photos — scanned pages, receipt photos, or multiple images that belong in one document — you can convert them all at once:
Go to convertfloor.com/tools/image-to-pdf
Click upload and select all your JPG files at once (hold Ctrl or Cmd to select multiple)
Drag to reorder the images if needed — the order you see is the order of pages in the PDF
Click Convert
Download the single PDF containing all your images as separate pages
Tip: If you need a searchable PDF (where the text in your images can be found by Ctrl+F), use convertfloor.com/tools/images-to-searchable-pdf instead — this runs OCR on all images before creating the PDF.
Page Size and Orientation Options
When converting images to PDF, two settings affect the output:
Portrait vs Landscape
Portrait is taller than wide — the standard for documents and text. Landscape is wider than tall — better for photos taken in landscape orientation. Choose based on how you shot the image.
Page Size (A4 vs US Letter)
A4 (210 × 297mm) is standard in most of the world. US Letter (8.5 × 11 inches) is standard in North America. If you are sending the PDF to someone in the US, use US Letter. For everything else, A4 is fine. The image will be scaled to fit the chosen page size.
How to Save a JPG as a PDF Without a Converter (Built-In Methods)
On Windows
Right-click the JPG file
Select Print
Choose Microsoft Print to PDF as the printer
Click Print — Windows saves a PDF to your chosen location
On Mac
Open the JPG in Preview (double-click or right-click → Open With → Preview)
Go to File → Print (Cmd+P)
Click the PDF dropdown at the bottom left → Save as PDF
On iPhone
Open the photo in the Photos app
Tap the Share button (square with arrow pointing up)
Tap Print
On the print preview screen, pinch outward with two fingers — this creates a PDF preview
Tap the Share button again and save to Files
The built-in methods produce a basic PDF with no quality settings. For better control over page size, orientation, and quality, use the online converter.
JPEG vs JPG — Is There a Difference?
No. JPEG and JPG are the same format. The difference is only in the file extension — .jpg is a shortened version of .jpeg used on older systems that required three-letter extensions. Both work identically and our converter accepts both.
JPG to PDF vs PNG to PDF
Both JPG and PNG can be converted to PDF. The difference is in the source image quality:
JPG uses lossy compression — good for photographs, smaller file size
PNG uses lossless compression — better for screenshots, diagrams, and images with text
For photos, convert from JPG. For screenshots or documents, convert from PNG for better sharpness. The conversion process to PDF is identical for both formats.
How to Convert a Photo to PDF on Android
Open Chrome on your Android device and go to convertfloor.com/tools/image-to-pdf. Tap the upload area and select your image from your phone's gallery. After conversion, tap the download link and save the PDF to your device. No app download required.
