How to: PDF to Long Image
- Select a PDF.
- Choose image width, pages, gap and format.
- Download one tall image (or a few parts for very long documents).
Sharing a PDF in a chat app usually means the recipient has to download and open it. A single long image can be scrolled straight away in WhatsApp, Telegram, Instagram, Slack or on a web page. This converter renders the pages you choose and stacks them vertically with an optional gap, producing one tall JPG, PNG or WEBP.
Common uses
- Share menus, flyers and price lists in chat apps.
- Post multi-page infographics and reports on social media.
- Embed short documents on websites as a scrollable image.
- Preview contracts or forms on phones without a PDF reader.
Tips for best results
- Convert only the important pages with a page range.
- Use a light grey gap so pages remain visually separate.
- Choose PNG for documents with small text and WEBP for smaller files.
- For individual page images use PDF to JPG instead.
How pages are stacked
Each page is rendered at the chosen width, so pages of different sizes line up neatly. The gap is added above, below and between pages using the background colour you choose. Text is rasterised at the selected width, so a wider image keeps small fonts readable.
Private conversion
Rendering happens in your browser with pdf.js, the same engine Firefox uses. Your PDF is never uploaded.

Browsers limit how tall a single image can be. The tool keeps each image under 16,000 pixels and, if allowed, splits longer documents into several parts, downloaded together as a ZIP.
Which width should I choose
1080 px matches most phone screens and social apps. Choose 1400 or 2000 px for small print or detailed drawings.
