PDF to Long Image — One Tall Picture for Social
Stitch every page of a PDF into one tall image, ready to post on social media or send in a chat.
Turn a whole PDF into a single image that runs from top to bottom. Share it in a chat or on social media as one picture, instead of sending the pages one by one.
How to turn a PDF into a long image (3 steps)
- Open your PDF.
- Choose the image width and the format (JPG or PNG).
- Create the long image and download it.
When it's useful
- Sending a multi-page document in a chat — the recipient scrolls straight through without opening a PDF.
- Posting announcements, menus, or price lists on social media — one image you can post right away.
- Keeping a record as an image — for example, a multi-page receipt that has to be attached to a system that only accepts pictures.
Options
- Width — 800, 1200 (the default), or 1600 pixels. Every page is scaled to the same width and stacked from top to bottom.
- Format — JPG gives a smaller file, which suits chat apps. PNG is sharper for text-only documents, but the file is larger.
Limits on length
Browsers have a ceiling on image size, especially on iPhone and in Safari. Go past it and you get a blank image. To prevent that, MyPDF automatically reduces the width when a file has many pages, keeping each image to a maximum of about 30,000 pixels long or 16 million pixels in total.
- About 10 A4 pages gives an image roughly 1,000 pixels wide.
- About 30 A4 pages drops to roughly 600 pixels wide, and the text may be too small to read.
For a very long document, split the PDF into sections first, or use PDF to JPG to get a separate image for each page.
FAQ
What is it best for?
Summaries, infographics, restaurant menus, and announcements — anything you want people to scroll through in a single image.
Will a file with dozens of pages be too long?
The tool can do it, but no more than 10–15 pages is recommended so chat apps can display the image properly.
Can I change the width?
Yes: 800, 1200, or 1600 pixels, depending on how sharp you need it.
The image looks blurry after I send it in a chat app. What can I do?
Chat apps often shrink long images when sending. If the document has small text, send it as a file instead of a photo, or divide the document into sections and make a long image for each one.
Should I choose JPG or PNG?
For chats or social posts, choose JPG — smaller files that load quickly. For text-only documents that need to be sharp, choose PNG.
Can I get one image per page instead?
Yes. Use the PDF to JPG tool, which gives you a separate image for each page in a ZIP file.
