Why Is My PDF to JPG Conversion Blurry?
Troubleshoot blurry PDF to JPG images by checking source scans, rendering resolution, JPEG compression and viewing size before exporting again.
Check the source first
Open the original PDF and zoom into the same text or picture. If it is already blurry, increasing export DPI cannot create missing detail. A PDF containing a low-resolution scan behaves differently from a document with vector text: vector content can render sharply at higher pixel resolutions.
Increase pixels before quality
If the source looks sharp but the exported text is soft, move from Email & Compact to Web & Social Media or Print & Docs. Higher DPI produces more pixels. Increasing JPEG quality alone does not increase image dimensions. Test one page first to avoid unnecessarily large outputs.
Check compression artifacts
Blocks or halos around letters can be JPEG artifacts. Use a higher JPEG quality or the Print preset’s PNG option. Disable an aggressive target-size setting while testing, because reaching that target may lower quality and shrink the image. Inspect Downloads for the actual export.
Avoid enlarging the image
A small export displayed much larger on a screen or page can appear soft. Compare at 100% viewing scale and choose enough pixels for the intended use. Rotating or cropping can improve composition but does not sharpen missing detail. For text editing or search, keep the PDF; image conversion does not perform OCR.
Frequently asked questions
Will higher DPI fix a blurry scan?
It can create a larger image but cannot recover detail that was never present in the scan.
Why does the same image look blurry when enlarged?
Enlarging a fixed pixel image spreads its pixels over a larger area and lowers apparent sharpness.
