PDF compression reduces file size so documents fit email, forms, and upload limits.
PDFs can contain text, fonts, vector art, and embedded images. Size grows quickly when pages are scanned or image-heavy.
Client-side Phase 1 compression on Konvert re-encodes pages as images to shrink the file. That trades some text selectability and vector sharpness for a smaller download.
Always prefer a larger target when readability matters, and keep an original copy when you still need searchable text.
