Question details
The user is looking for ways to preserve sharp text and prevent blurry or jagged edges when converting PDF pages into JPEG images.

- Device & OS

- Scenario
- Exporting pages from a PDF document to image files to be shared, printed, or published online.
- Observed behavior
- Exported JPEG files exhibit jagged, blurry, or low-quality text artifacts due to image compression and resolution limits.
Determine if your final output strictly requires a JPEG file format, or if you have the flexibility to use a lossless format like PNG for perfectly sharp text.
Export PDF as a PNG for Lossless Quality
PNG format uses lossless compression, making it superior for preserving sharp text and crisp lines from PDFs without introducing compression artifacts.
JPEG is designed primarily for photographs and uses lossy compression to reduce file size. This compression often struggles with high-contrast edges like text, causing blurriness.
By switching your export format to PNG, the image will retain 100% of the original text sharpness.
Launch your PDF editor and open the document you wish to convert.
Locate the 'Convert' or 'Export' menu at the top toolbar and select 'PDF to Picture' or 'PDF to Image'.
In the output format dropdown menu, change the selection from 'JPG' or 'JPEG' to 'PNG'.
Click 'Export' or 'Save' to process the document and save your high-quality, lossless images.
Maximize JPEG Resolution and Quality Settings
If you are required to use JPEG, increasing the export resolution (DPI) and selecting the highest quality setting will significantly minimize text blurriness.

Frequently Asked Questions
Why does text look blurry when I convert a PDF to JPG?
JPG uses a lossy compression algorithm optimized for photographs, not text. To keep file sizes small, it discards minor image data, causing compression artifacts that make sharp, high-contrast edges like fonts look blurry or jagged.
What is the best DPI setting for exporting PDFs to images?
For standard digital viewing on screens, 150 DPI is usually sufficient. However, if you want to maintain sharp font quality, print the image, or allow users to zoom in, setting the export resolution to 300 DPI is highly recommended.
Can I convert multiple PDF pages into images at the same time?
Yes, most modern PDF editors like WPS Office offer batch processing features. You can use the 'PDF to Picture' tool and choose to export all pages as individual, high-quality images with a single click.
