JPG to PDF: Common Problems and How to Fix Them
Quick summary
- Choose the page size and orientation to match your document, and set margins deliberately.
- Use the black-and-white filter for photos of paper documents, and compress if the file is too big.
- Good lighting and a flat page matter more than any setting.
Converting photos to a PDF should be easy, yet results sometimes look wrong: pages are rotated, the text is blurry, or the file is far too large. Here is what causes each problem and what to do about it.
Problem 1: images appear sideways
Phones often store a rotation flag instead of rotating the pixels. Some programs ignore it. If a page comes out sideways, rotate it afterwards with Rotate PDF, or set the orientation correctly when you convert.
Problem 2: the text is blurry
Blur usually comes from the photo itself, not from the conversion. Retake it with:
- Bright, even light with no shadow across the page.
- The paper flat on a table, not curved.
- The phone parallel to the page so that edges are straight.
- A steady hand, and a tap to focus on the text.
Problem 3: the PDF is far too big
A dozen full-resolution phone photos can add up to tens of megabytes. After converting, run the file through Compress PDF. For tips on how to choose the level, see How to Compress a PDF Without Losing Quality.
Problem 4: white borders or cropped edges
JPG to PDF lets you choose the page size (such as A4 or Letter), the orientation, the margins and how the image is scaled. Pick "fit" if you want to see the whole image, or a smaller margin if you want it to fill more of the page. If every page should match its image exactly, choose the option that sizes the page to the picture.
Problem 5: pages are in the wrong order
Images are usually added in the order you select them or by file name. Rename them with numbers (01, 02, 03) before converting, and check the order of the list before you run the tool. If it is still wrong, Organize PDF lets you drag pages into place.
Problem 6: photos of paper look grey and dull
Camera photos of white paper often look slightly grey. The black-and-white filter in the JPG to PDF options gives a clean, high-contrast look that is closer to a real scan and usually produces smaller files too.
