What image formats are supported?

PNG and JPG/JPEG images are supported. Drop multiple images to combine them into a single PDF document.

Can I combine multiple images into one PDF?

Yes. Upload as many images as you want: each image becomes one page in the final PDF. You can reorder them before converting.

Are images compressed during conversion?

Images are embedded at their original resolution. The resulting PDF preserves the quality of your source images.

Do my files get uploaded to a server?

No. The conversion runs entirely in your browser using pdf-lib. Your images and the resulting PDF never leave your device.

What happens to the page size when converting images?

Each image is placed on its own page sized to match the image dimensions. The PDF page adapts to the aspect ratio of each image.
