Frequently Asked Questions about Compress PDF

How does AllEdits compress PDFs?
Our engine renders each PDF page via PDF.js on a browser Canvas and re-encodes it as a JPEG at a tuned quality level. This reduces file size significantly by converting page content to compressed image data. Note: after compression, text becomes part of an image layer (not selectable vector text).
Does compression affect readability?
Text remains visually legible at recommended presets, though extremely aggressive settings (High/Extreme) may reduce sharpness on small print. For documents where text selectability or embedded hyperlinks are critical, use Low compression or keep a backup of the original.
