What is a PDF to Long Image Converter Tool?
A PDF to Long Image Converter is a free online tool that takes all the pages of a PDF document and stitches them together vertically into a single continuous long PNG image. Unlike a standard PDF to image converter that creates one separate image per page, this tool merges every page into one tall scrollable image — perfect for sharing, embedding, or archiving an entire document as a single visual file.
This type of output is especially popular for sharing documents on platforms that do not support PDFs natively. Social media platforms like Twitter, Discord, Reddit, and WhatsApp do not display PDFs inline — but an image can be viewed, scrolled, and shared instantly. A long scrollable image lets anyone read a full document without needing to download or open a PDF reader.
Toolnex AI's PDF to Long Image Converter runs entirely inside your web browser using the PDF.js rendering engine. Your PDF is never sent to any server — all rendering and image stitching happens locally on your device using the HTML5 Canvas API. This makes it one of the most private and secure online PDF tools available, with zero risk of data exposure.
The tool offers several customisation options: you can set the render quality (High, Medium, or Low) to control the sharpness versus file size trade-off; you can enable or disable page separator lines between stitched pages for better visual clarity; and you can choose whether to apply a white background behind each page, which is important for PDFs with transparent or dark backgrounds.
Common use cases include sharing full PDF documents on messaging apps and social platforms, creating scrollable product catalogues or portfolios, archiving reports or research papers as a single image file, generating long-form visual content from structured PDFs, and embedding complete documents as inline images on websites or blogs. Whatever your use case, this tool delivers a fast, private, and watermark-free result every single time.

Frequently Asked Questions
Yes, it is 100% free with no hidden fees, no subscription plans, and no usage limits. You can convert as many PDF files to long images as you want without spending anything at all.
Absolutely. All processing happens entirely within your browser using PDF.js and the HTML5 Canvas API. Your PDF files are never uploaded to any external server and never seen by any third party. Your documents remain completely private on your own device from start to finish.
PDF to Image converts each page into a separate image file (one file per page), while PDF to Long Image stitches all pages into a single tall continuous PNG. The long image is ideal for sharing an entire document as one file — for example on social media, messaging apps, or website embeds — without needing to share multiple separate files.
No, absolutely not. Toolnex AI never adds any watermark, logo, or branding to your converted image. The output file is completely clean and ready for professional use or sharing anywhere.
When this option is enabled, a thin horizontal line is drawn between each stitched PDF page in the final long image. This makes it easy to visually identify where one page ends and the next begins, which is particularly helpful for multi-page documents like reports and books.
There is no hard limit imposed by the tool itself — performance depends on your browser's available memory. For best results, files under 50MB and PDFs with fewer than 50 pages are recommended. Very large or high-page-count PDFs can produce extremely large image files and may take more time to process.
No installation and no account is required whatsoever. Simply open the page in your browser, upload your PDF, configure your options, and convert immediately. The entire tool runs inside your browser with zero setup required.
For best results, use the latest version of Google Chrome, Microsoft Edge, or Firefox. These browsers provide the best performance with the PDF.js rendering engine and Canvas API. Safari on macOS and iOS also works well for most documents.
