Merge PDF into One Image
Convert a multi-page PDF into a single long JPG or PNG image, with every page kept in full resolution.
Ever tried to send a PDF over WhatsApp or Slack and watched it show up as a dead file icon nobody opens? Turning it into one scrollable image fixes that instantly.
The Problem
Most chat apps and messaging platforms preview images inline but treat PDFs as generic attachments people have to download first. A scanned contract, a multi-page report, or a signed agreement gets buried as a file link nobody bothers to open. Pasting a PDF into a slide deck or webpage is even messier, since it usually needs a separate viewer plugin or breaks the layout entirely.
The Solution
Auto Merge Images converts each PDF page into an image and stitches them vertically into one continuous JPG or PNG, so the whole document scrolls like a single tall picture. Because the conversion runs entirely in your browser using the PDF.js and Canvas APIs, the file never touches a server, which matters when the PDF contains contracts, medical records, or anything else you would not want passing through third-party infrastructure.

Frequently Asked Questions
Does the PDF get uploaded to a server during conversion?
No. The entire conversion happens locally in your browser using JavaScript, so the PDF file and its pages never leave your device or touch our servers.
How many pages can I merge into one image?
There's no hard page limit. We've tested PDFs with over 100 pages successfully, though very long documents produce a correspondingly tall output image, so plan for scrolling.
Will the output image lose quality compared to the original PDF?
Not if you keep the quality slider at a high setting. The tool renders each page at its native resolution, so text and details stay sharp in the merged JPG or PNG.
Can I choose PNG instead of JPG for the final image?
Yes. PNG keeps text and line art perfectly crisp with no compression artifacts, while JPG produces a smaller file, useful when the document is photo-heavy.
