One picture to scroll through
Sending a PDF in a chat means the other person has to tap it, wait for it to open in another app, and pinch around. A long image opens right in the conversation and scrolls like a web page. That suits menus, price lists, itineraries, short reports, bills, results and anything someone will glance through on a phone.
This page draws each page and stacks them top to bottom into one tall JPG, with a thin grey gap between pages so it’s clear where one ends.
How many pages fit
Browsers can’t make an image bigger than about 16 million pixels, so a long image has a natural limit:
| Quality | A4 pages per image |
|---|---|
| Standard (the default here) | about 7 |
| High | about 4 |
Standard is the default because it fits the most pages and still reads clearly on a phone. Pick High when the pages have small print people will zoom into.
When the PDF has more pages than fit, you get several long images in order, named for the pages in each, like menu-long-pages-1-7.jpg and menu-long-pages-8-14.jpg. The note under the result says how they were grouped. You can download them as one .zip or share them one by one.
Sending it without losing sharpness
Chat apps shrink photos to save data, and a very tall image gets shrunk a lot. Small text that was crisp turns to mush. The fix is to send it as a file rather than a photo:
- WhatsApp: tap Attach, choose Document, and pick the image. It arrives exactly as it left.
- Telegram: send it as a file, not as a photo.
- Email sends it as it is.
If it’s going to Instagram or a status, it’ll be cropped or shrunk anyway. Use PDF to JPG with one image per page for that.
Only some pages
Under More options, you can choose pages, like 1-3 for the first three, so the image holds just what you want to show.
Nothing leaves your phone
The pages are drawn and stacked by your own browser. The PDF isn’t uploaded, which matters when it’s a bill, a result or anything with your name on it. If you later need the pages as a PDF again, JPG to PDF puts images back into one.
