How to Prepare Images for a Clean PDF
Good source images lead to a better PDF. Here’s how to prepare them.
Resolution and Size
Use images that are clear enough for their purpose. For documents, around 150–300 DPI (or equivalent pixel dimensions) is usually enough. Very large images can slow conversion and bloat the PDF.
Format
We support JPEG, PNG, and WebP. JPEG is fine for photos; PNG is good for screenshots or graphics with text. WebP is supported and will be converted for the PDF.
Order
Add images in the order you want pages. Use Remove and re-add if you need to change the order before converting.
Limits
Keep the total under 20 MB and use up to 50 images per PDF for reliable, fast conversion.
