Question 1

How do I combine images into one PDF?

Accepted Answer

Drop multiple images, drag to reorder, choose page size (A4/Letter/fit), set margin, click Build PDF. Single PDF downloads with one image per page.

Question 2

What image formats are supported?

Accepted Answer

JPG, PNG, WebP, GIF, BMP. WebP/GIF are auto-converted to JPG inside the PDF.

Question 3

Is there a page limit?

Accepted Answer

No hard limit, but very large batches (100+ high-res images) may slow your browser. For best performance, batch in chunks of 20–50.

Question 4

Are my files uploaded?

Accepted Answer

No. PDF assembly runs entirely in your browser using pdf-lib. Files never leave your device.
