Question 1

Does PDF247 upload my PDF?

Accepted Answer

No. PDF reading, page rendering, image encoding, and ZIP creation happen in the current browser without sending the file to a PDF247 server.

Question 2

Which image formats are supported?

Accepted Answer

PNG, JPG, and WebP are supported. PNG suits text and diagrams; JPG or WebP can reduce files containing many photos.

Question 3

Can I convert only some PDF pages?

Accepted Answer

Yes. Choose a custom range such as 1-3, 5, 8 or select and deselect pages from the thumbnail grid.

Question 4

Why can a large PDF take longer?

Accepted Answer

Time and memory use depend on page count, page complexity, resolution, and device performance. Fewer pages or a lower resolution reduces both.
