PDF to Long Image: Step-by-Step Guide
Turn multiple PDF pages into a single tall, scrollable PNG or JPG. Choose the output width, page gap and format, then download one continuous image. This free PDF tool targets a specific document task rather than offering an unrelated bundle of features. Processing occurs locally after the JavaScript libraries load.

What Is a PDF to Long Image Converter?
A PDF to long image converter stacks each PDF page vertically, producing one tall picture rather than a ZIP of separate pages. This is useful for sharing a multi-page instruction sheet, simple report, or handout in a chat, publishing a continuous reference image, or scrolling through pages in a phone gallery. This tool renders page appearances; text in the final PNG or JPG is not selectable.
How to Convert PDF Pages into One Long Image
Choose a PDF or drag it onto the upload area. Select an image width, PNG or JPG output, and the gap you want between pages. Click Create Long Image. The converter reads the PDF page geometry, finds a safe size for your browser, draws pages in their original order, and offers the finished image as a download. Open the output to confirm that all pages are present and readable.
Choosing PNG or JPG for PDF Pages
PNG uses lossless compression and is a good default for diagrams, tables, screenshots and text-heavy documents. JPG is often smaller for photographic pages, although letters and thin lines may show compression artifacts. A width of 1080 pixels is practical for phones and chat apps, while 1440 pixels can make small text easier to read on modern displays.
Why Very Long PDFs Need a Size Limit
Browsers limit the dimensions and memory used by a single canvas. Combining hundreds of large PDF pages into one extremely tall bitmap can fail or create a blank image. This converter automatically reduces width to fit conservative limits when possible. If the result would still be too large, split your PDF into smaller parts or use the separate-page PDF to PNG tool. This safeguard avoids silently truncating pages.
Common Uses for a Long PDF Image
Save presentation notes as a vertically scrolling image, share a short manual in a single message, prepare a mobile-friendly reference graphic, and combine a multipage invoice or checklist for internal review. Remember that a flattened image does not preserve hyperlinks, selectable text or editable PDF form fields.
Keep the Original PDF
A long image is a visual export, not a replacement for an accessible PDF. Keep your source PDF for printing, searching, copy-and-paste, archiving and assistive technology. For documents with signatures, confidential content or legal importance, distribute the original PDF through your approved secure workflow.

Frequently Asked Questions
Can I convert all PDF pages into one image?
Yes, for documents that fit safe browser canvas limits. The tool automatically scales long outputs down when needed and reports unsupported sizes instead of cutting off pages.
Is PNG or JPG better for PDF text?
PNG usually keeps small text and line drawings sharper. JPG may be preferable for photos when a smaller file matters.
Will links or selectable text remain in the image?
No. PDF pages become raster pixels. Keep the original PDF if you need text selection, links, or accessibility features.
Do I need an API key or upload my PDF?
No paid API or key is needed. Page rendering runs locally in your browser after the open-source PDF library loads.
