When to convert JPG to PDF
A JPG is great for a single picture. Once you have several pages that belong together, a PDF is easier for everyone to handle.
- Expense reports: photograph each receipt, then send your manager one PDF instead of a pile of images.
- School work: snap handwritten pages and submit them as one file in the right order.
- Forms and applications: many portals ask for a single PDF with all supporting documents.
- Printing: a print shop or office printer handles one PDF faster than many separate photos.
A PDF also keeps the page order fixed. The person who opens it sees page 1, then page 2, exactly as you arranged them.
Choosing page size, orientation and margins
| Setting | Pick this when |
|---|---|
| Fit to image | You want each page to match the shape of the photo. With Margin set to None there is no white border. Good for viewing on screen. |
| A4 | You plan to print or submit an official document in a country that uses A4 paper, which is most of the world. |
| US Letter | You print in the United States or Canada. |
| Orientation: Auto | Your photos mix tall and wide shots. Each page turns to match its image. |
| Margin: Small or Large | You want white space around the photo so nothing is cut off by the printer. |
Not sure? Use A4 or US Letter with Auto orientation and a small margin. It looks clean on screen and on paper.
Tips for a sharper, smaller PDF
Take document photos in daylight, hold the phone flat above the page and fill the frame. A straight, bright photo makes a far more readable PDF than any setting can.
Crop away the table or floor around the paper first with Crop Image. If the finished PDF is too large for an email or upload form, run it through Compress PDF. Have PNG screenshots instead of photos? The PNG to PDF tool works the same way.
