Turn a multi-page PDF into one tall image that people can simply scroll through in a chat or social feed without downloading a PDF. Choose all pages or a page range, set the image width (every page is scaled to the same width), the gap between pages, the background color and outer padding, and export as JPG (smaller) or PNG (lossless). Browsers cap a single canvas at roughly 32,000 pixels tall, so for long documents the tool automatically splits the result by page into several images and tells you in advance how many to expect — no blank output or crashes. Everything runs in your browser and nothing is uploaded.

## How to use

1. Upload a PDF file
2. Pick the page range, width, gap and background color, and check how many images will be produced
3. Click Create long image and download it (several images download as a ZIP)

## Features

- Stacks pages vertically into one image
- Adjustable width, gap, padding and background
- Automatic split when over browser limits
- JPG or PNG, processed locally

## FAQ

### Why did I get several images?

Browsers limit how tall a single canvas can be (around 32,000 px, less on phones). When there are many pages or the width is large, the tool splits the output by page so each image stays under the max height you chose and opens reliably.

### The long image looks blurry — what can I do?

Increase the width (for example 1600 or 2000 px) and choose PNG. A wider image is sharper but also larger.

### Can I stitch only some of the pages?

Yes. Choose Specific pages under page range and enter something like 1-3,5; only those pages are stitched.

### Are my files or data uploaded?

No. Everything runs locally in your browser with no network upload, and is discarded when you close the page.
