# Convert PNG to PDF.

> PNG screenshots into one PDF — assembled on your device.

Bundle PNG screenshots, scans or graphics into a single PDF **without anything leaving your browser**. Each PNG becomes one page sized to the image, in the order you arrange; transparent areas are flattened to white, since PDF pages have no transparency. Perfect for turning a screenshot trail into one shareable document.

**No uploads · No ads · Free & open source.**

## How it works

1. Drop files anywhere on the page, click to browse, or paste with Ctrl/⌘ + V.
2. Pick a quality or preset — or set an exact target size and let the tool find it.
3. Compress, compare before/after, and download — individually or as a ZIP.

## Screenshots to a single document

The classic use: a bug report, a chat export or a step-by-step walkthrough captured as a dozen screenshots. Drop them all, order them with the arrows, convert — and send one PDF instead of twelve attachments that arrive shuffled. Page size follows each image’s pixels, so nothing is cropped or letterboxed.

## Keeping the PDF small

The quality slider re-encodes every page as JPEG inside the document. Screenshots tolerate 75–85 well; photographic PNGs can go lower. If the combined file still needs to hit a limit — a 2 MB application-portal cap, say — run the result through [Compress PDF](https://compress-pro.com/compress-pdf) with target-size mode afterwards.

## Frequently asked questions

### What happens to PNG transparency?

PDF pages are opaque, so transparent regions are flattened onto white — logos and UI screenshots come out looking like they would on paper. If you need transparency preserved, PDF isn’t the format for it.

### How do I order the pages?

Pages follow the file list — use the row arrows to rearrange before converting. The result downloads as a single images.pdf with one PNG per page.

### Why is the PDF bigger than my PNGs?

Pages are re-encoded as JPEG inside the PDF, which usually shrinks screenshots — but flat graphics with few colors can grow slightly. Lower the quality slider to trade sharpness for size; around 80 is a good screenshot setting.

### Is it private?

Yes. The document never leaves your browser — nothing is uploaded, and the server only delivers this page. That makes it safe for contracts, invoices, medical records — anything you would not email to a stranger. Want proof? Run one file through, switch your connection off, and run another — it still works.
