Drop PNG screenshots, charts or scans and get one PDF. Lossless is on by default, so small text and thin lines stay exactly as sharp as the PNG; switch it off for a much smaller file.

## How to use it

1. Drop the PNG files and put them in order.
2. Keep Lossless on for screenshots and diagrams, or turn it off for photos.
3. Choose the page size and press Make PDF.

## Details

- **Input:** PNG, plus JPG, HEIC, WebP, AVIF, GIF and BMP
- **Lossless pages:** PNG data embedded as-is after drawing (Flate compression), transparency kept
- **Smaller pages:** Lossless off: JPEG quality 92 on a white background, typically 3–10× smaller for photos
- **Pages:** A4, Letter or the image's own size (150 DPI)

## Questions

### Are my files uploaded?

No. The page loads its code once, then reads and processes your files inside the browser tab. Nothing is sent to a server; you can confirm it in your browser's network panel while a file is processed.

### Why is my PNG-based PDF large?

Lossless pages keep every pixel. Screenshots compress well, but photos saved as PNG do not; turn Lossless off for those, or use Compress PDF afterwards.

### What happens to transparent areas?

With Lossless on they stay transparent, which shows as white in PDF readers. With it off they are filled with white.
