FAQ

Do my images ever leave my computer?
No. Everything happens locally in your browser using pdf-lib — no upload, no server, no third-party API. JPEGs and PNGs are embedded losslessly; WebP is re-encoded to JPEG before embedding.
What's the difference between Contain, Cover, and Stretch?
Contain scales the image to fit inside the page with whitespace on the short edge. Cover scales to fill the page and crops the overflow. Stretch distorts the image to fill the page exactly — aspect ratio is not preserved.
What does Auto page size do?
Each image becomes a page sized to match its own pixel dimensions (treated at 72 DPI). Use this when you want one image per page and no whitespace. The fit and margin settings are ignored in Auto mode.
Can I mix portrait and landscape images?
Yes. With Orientation set to Auto, each page follows the longer edge of its image. Lock to Portrait or Landscape to force every page the same way (useful for printable booklets).
Why does my transparent PNG show black in the PDF?
Most PDF viewers render transparent page regions as black, not as the surrounding UI colour. If your image has transparent corners, pick the White background option so the page itself is opaque white behind the image.
