PDF to Long Image

PDF to Long Image is an online tool that stitches an entire PDF into one vertical image. Unlike the page-by-page PDF to Image tool, it joins all selected pages from top to bottom into a single continuous long image, which is ideal for scrolling on phones, sharing on WeChat or social media, and embedding in web pages. The whole conversion runs locally in your browser and files are never uploaded.

Key Features

• All pages in one image: merges every PDF page top to bottom into a single vertical image ready to share.
• Format choice: export as JPEG or PNG; JPEG is smaller for sharing, PNG keeps cleaner edges.
• Multiple resolutions: standard, clear, and HD settings balance quality against file size.
• JPEG quality: a slider fine-tunes compression when JPEG is selected.
• Custom page range: convert all pages or a subset such as “1-3, 5, 8-10”; it tolerates Chinese commas and tildes.
• Local processing: conversion happens entirely in the browser with no upload, keeping files private.

Use Cases

• Turn contracts, manuals, or slides into one long image for easy scrolling on mobile.
• Combine pages into a vertical image for WeChat, social feeds, chats, or web layouts.
• Convert only the pages you need using the page-range option.
• Control output size by combining format, resolution, and JPEG quality.

How to Use

1. Click the upload area or drag a PDF in; the total page count is read automatically.
2. Choose the output format and resolution, then set all pages or a specific range.
3. Click Make long image, preview the result, and Download to save the image.

About the Height Limit

Browsers cap how tall a single image can be. When there are many pages, the tool automatically reduces resolution so the image can still be produced; if the content exceeds the limit entirely, it asks you to narrow the page range so you can convert fewer pages at a time.

FAQ

Q: Is this tool free?

A: Yes. It runs directly in your browser with no registration or installation.

Q: What is the difference between PDF to Long Image and PDF to Image?

A: This tool merges all pages into one continuous vertical image. To export each page as a separate image, use the PDF to Image tool instead.

Q: Are my files uploaded?

A: No. Conversion runs entirely in your browser; files are never uploaded and the resulting image stays on your device.

Q: Why is the image softer in quality, or why does it say it cannot fit?

A: Due to the browser’s single-image height limit, resolution is reduced automatically when there are many pages; if it still exceeds the limit, narrow the page range and convert in batches.

Q: Can I convert an encrypted PDF, and does it work on mobile?

A: Encrypted PDFs must first be unlocked with the PDF Unlock tool. The page is mobile-friendly, so you can generate and download long images on phones and tablets.
