How to Fix "Image Is Too Wide" Error When Exporting PDF to JPEG
Question details
The user is unable to export a large PDF collage to a JPEG file due to an image width dimension error.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Attempting to export a large PDF document (such as a collage) to a JPEG image format.
- Observed behavior
- The software rejects the export and displays an "Image Is Too Wide" error because the output pixel dimensions exceed the maximum supported size limit.
Before troubleshooting, verify the physical dimensions of your PDF document (e.g., by pressing Ctrl+D in Acrobat to view Document Properties) to understand the exact size you are trying to export.
Reduce the Output Pixel Density (DPI)
Lowering the export resolution keeps the physical dimensions and aspect ratio intact while preventing the total pixel count from exceeding the software's limit.
Acrobat has a hard limit on the maximum pixel dimensions an exported image can have (typically around 32,766 pixels on any side). When you export a physically large PDF at a high DPI (Dots Per Inch), the resulting image exceeds this limit.
Open the large PDF in Adobe Acrobat. Go to 'File' in the top menu, hover over 'Export To', select 'Image', and then click 'JPEG'.
In the Save As dialog box that appears, click on the 'Settings' (or gear icon) button located near the 'Save' button.
Look for the 'Resolution' dropdown menu in the File Settings window. Change it from 'Automatic' or a high value (like 300 pixels/inch) to a lower value such as 150 or 72 pixels/inch.
Click 'OK' to confirm the settings, choose your save location, and click 'Save'. The image will now export successfully without triggering the width error.

Rasterize the PDF Using an Image Editor
If adjusting the DPI in Acrobat still fails, use a dedicated image editing software to open and rasterize the PDF directly.
Export Large PDFs to Images Seamlessly with WPS Office
If you are struggling with Acrobat's dimension limits, WPS Office provides a dedicated 'PDF to Picture' tool that handles large canvases and collages efficiently, allowing you to customize the output quality without frustrating width errors.
- 1. Open the PDF in WPS: Launch WPS Office and open your large PDF file in the WPS PDF reader.
- 2. Select PDF to Picture: Navigate to the 'Tools' tab on the top ribbon and click on the 'PDF to Picture' button.
- 3. Configure Output Settings: In the pop-up dialog, select 'Export to Picture', choose 'JPG' as your desired format, and adjust the quality slider to an optimal level.
- 4. Export the Image: Click 'Export' to save your large PDF as a high-quality JPEG seamlessly.

Frequently Asked Questions
What is the maximum image dimension Adobe Acrobat can export to JPEG?
Adobe Acrobat generally limits image exports to 32,766 pixels in either dimension. If your PDF's physical size combined with a high DPI exceeds this pixel limit, Acrobat will trigger the "Image Is Too Wide" or "Image Is Too Tall" error.
Does reducing the DPI affect the quality of my exported JPEG?
Yes, lowering the DPI (Dots Per Inch) reduces the pixel density, which can make the image less sharp when zoomed in tightly. However, for large collages intended for general screen viewing, 72 to 150 DPI is usually sufficient and prevents export errors.
Can I split the PDF to avoid the width error?
Yes. If you need to maintain an extremely high resolution, you can crop the PDF into smaller sections, export each section individually as a JPEG, and then stitch them back together using image editing software.
