What is a PDF long image?

A PDF long image stitches every page vertically into one large picture for quick full-document previews, social sharing, or archiving.

This tool renders and combines pages locally with pdf.js; no upload required.

How to use

Three steps to create a long image:

  • Upload a PDF document.
  • Choose the output format and sharpness.
  • Click "Generate long image", preview, then download.

Tips

  • For large multi-page documents use JPEG to keep the file smaller.
  • Long image height is limited by the browser; lower sharpness for very large files.
  • To export pages individually, use the "PDF to JPG" tool instead.

Frequently Asked Questions

What is a long image?+
A long image stitches every page of a PDF vertically into one complete picture for continuous reading, ideal for sharing on social platforms or archiving.
How do I choose the sharpness?+
Sharpness is the render scale: 1x is smallest, 3x is sharpest. Very large images may hit browser canvas limits; lower the scale in that case.
PNG or JPEG?+
PNG is lossless with crisp text but larger; JPEG is smaller and suits big documents. Use JPEG for regular documents and PNG for documents with screenshots.
Is the document uploaded to a server?+
No. The PDF is rendered and merged locally with pdf.js in your browser and never leaves your device.
