Keep PDF screenshots readable as JPG

Why this happens

Lossy image compression can introduce halos around letters and fine lines. Enlarging a low-resolution result will not restore detail.

What to try first

Keep the highest-quality result that fits your destination. Try PNG instead for pages dominated by text, tables or diagrams.

Try it on a fresh copy

1. Open the PDF and convert its pages to JPG.
2. Download the images and check that you have every required page.
3. Look closely at small lettering. If you see distracting compression marks, try PNG instead.

How to tell whether it worked

Check small print for compression artifacts and confirm that all required pages were converted.
