How to Split a Tall PDF Page into Multiple JPEG Images
Question details
The user needs to divide a single elongated PDF page into multiple fixed-size JPEG image tiles.
- Product
- PDF Editors / Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Preparing graphics for an email marketing system that requires specific image block dimensions (e.g., 800 by 800 pixels).
- Observed behavior
- The user has an 800x3200 PDF page but needs four separate 800x800 JPEG images, and standard PDF editors lack a one-click tile splitting feature.
Verify the exact image dimensions required by your email marketing platform. Since most PDF readers cannot slice a single page into precise pixel-based images natively, having a basic image editing tool installed will streamline the process.
Export PDF to Image and Slice in an Image Editor
Since direct precise pixel splitting isn't natively supported in Acrobat, exporting the PDF as a single image and slicing it in a photo editor is the most reliable method.
PDF editors focus on document layout rather than pixel-perfect graphic slicing. By converting the PDF to a high-resolution JPEG first, you gain access to the precise cropping tools available in image editors like Photoshop.
Open the tall PDF file in your PDF editor. Navigate to File > Export To > Image, select JPEG, and save the file to your computer.
Launch Adobe Photoshop or a similar image editor and open the newly created JPEG image.
Select the Slice Tool or Crop Tool. Manually configure the grid or selection box to create four exact 800-by-800-pixel sections.
Use the 'Save for Web' feature or save each cropped section independently as a high-resolution JPEG file.
Use Free Online Image Splitting Tools
If you do not have professional image editing software, you can export the PDF to an image and use a free web-based tool to split the tall graphic automatically.

Frequently Asked Questions
Can I split a PDF page into smaller PDF pages directly?
While you cannot directly split a single page into fixed-size grid tiles natively in most standard PDF viewers, you can use the Crop tool in an advanced PDF editor to isolate the top quarter, save it as a new PDF, and repeat this process for the remaining sections.
Why do my exported JPEG images look blurry?
This usually happens if the PDF-to-Image export resolution is set too low. Check your software's export settings before converting the PDF and ensure it is set to a minimum of 150 or 300 DPI (Dots Per Inch).
Is there an automated way to slice images for email marketing?
Yes. While standard PDF software doesn't offer this, many email marketing platforms have built-in image croppers. Alternatively, you can use dedicated slicing software like Photoshop's Slice Tool to lay out a grid and export all tiles simultaneously.
Does WPS PDF support exporting long PDFs to image?
Absolutely. The 'PDF to Picture' feature in WPS Office allows you to export entire long PDF pages, or specific sections, into high-quality JPEG or PNG images seamlessly with customizable quality settings.
