How to Compress a PDF Without Losing Text Readability
Reduce PDF file size while keeping text sharp and readable. Compression settings explained.
Text quality is preserved differently from image quality during PDF compression. Understanding this helps you choose the right level.
How PDF Compression Works
Text in PDFs is vector data — it compresses perfectly without quality loss at any level. Images are raster data — high compression can cause pixelation. FixMyPDF's compression primarily targets images, leaving text vectors untouched.
Recommended Setting
Low or Medium compression maintains image quality while significantly reducing file size. High compression is better for archiving where file size matters more than image sharpness.
Testing
After compressing, zoom in to 200% on text and images. Text should remain crisp. Images may show slight softening at High compression — acceptable for most uses.
