When should I use PNG instead of JPG for PDF creation?

Use PNG for screenshots, UI mockups, and logos needing sharp edges or transparency. JPG is better for noisy camera photos at smaller sizes.

Why is my PNG-based PDF larger than a JPG version?

Lossless PNGs are bigger for photographic content. Consider JPG for photo albums, PNG for diagrams.

How do I avoid blurry text in slides exported as PNG?

Merge PDFs after generating the PNG-based PDF from QwerPDF.

Does QwerPDF strip metadata from PNGs?

Assume metadata may remain unless you strip locally first for privacy (GPS in photos).

Use split/merge tools or regenerate with correct upload order—faster than page reorder in some viewers.

Transparency compositing over gray backgrounds—check flattening settings if available.
