A PDF in a group chat is a file people have to tap, download and open. A single tall image shows up right in the chat and scrolls like a web page. This tool draws the pages you pick at one width and stacks them top to bottom, with an optional gap, into one JPG or PNG. It runs in your browser, and if the result would be taller than a browser can make, it splits it into parts instead of failing.
How to use it
- Choose a PDF or drop it here.
- Pick a width, the gap between pages and, if you like, a page range.
- Press Create long image and check the preview.
- Download the image, or every part as a ZIP if it was split.
Frequently asked questions
Why would I want one long image instead of a PDF?
Chat apps like WhatsApp show an image straight in the conversation, while a PDF has to be downloaded and opened. One tall image lets people scroll through a menu, notice or certificate without leaving the chat.
Why was my image split into parts?
Browsers can only create images up to a certain size: about 32,000 pixels tall, and on iPhone and iPad about 16.7 million pixels in total. At 1080 px wide that is roughly 15,500 px, about 11 A4 pages. Longer documents are split into parts in page order. Pick a smaller width to fit more pages in one image.
Which width should I choose?
1080 px suits phones and WhatsApp. Use 1440 or 2048 px if the PDF has small print that people will zoom into, and 720 px for the smallest file.
Will WhatsApp make it blurry?
WhatsApp compresses images it sends as photos, and very tall ones get shrunk. If the text ends up hard to read, send the image as a document instead, which keeps it unchanged.
Is my PDF uploaded?
No. The pages are drawn and stitched together in your browser tab. Nothing is sent anywhere.
