Quick answer

What you need to know first

Use original images, avoid enlarging small files, choose Fit when edges matter and do not repeatedly resave JPGs before PDF conversion.

  1. 1Start with the original image.
  2. 2Avoid screenshots of images.
  3. 3Use a page size close to the image shape when possible.
  4. 4Check the PDF before compressing it.

Sharpness is mostly decided before export

If an image is already low resolution, placing it in a PDF will not restore detail. The PDF can preserve pixels, but it cannot invent missing pixels.

For screenshots with small text, PNG often stays sharper than JPG. For camera photos, JPG is usually fine if the original has enough resolution.

FAQ

Common questions

Does PDF make images blurry?

PDF itself does not have to blur images. Blurriness usually comes from low source resolution, stretching or heavy compression.

Should I use Fit or Fill?

Use Fit when the whole image must remain visible. Fill can look larger but may crop edges.
