Question 1

Why was PDF invented in the first place?

Accepted Answer

Before PDF, sharing documents between different computers and operating systems was a persistent headache — fonts would be missing, margins would shift, and graphics would break. Adobe co-founder John Warnock envisioned a format that would preserve the exact visual appearance of any document on any system. That idea became PDF, and it solved the "what you see is what I see" problem that had plagued publishing for years.

Question 2

What DPI setting should I choose?

Accepted Answer

72 DPI is fine for quick screen previews. 150 DPI (the default) works well for most uses including emails and presentations. Choose 300 DPI when you need print-quality images or need to zoom into fine details.

Question 3

What about multi-page PDFs?

Accepted Answer

Each page of your PDF becomes a separate JPG image. You can download them individually or grab all pages at once in a single ZIP file. Progress is shown as each page is converted.

Question 4

Can I adjust the JPG quality?

Accepted Answer

Yes. A quality slider lets you choose between smaller file sizes and sharper images. The default of 92% offers a good balance. Lower values shrink files significantly with minimal visible difference for most documents.
