Frequently asked questions

How much smaller will my PDF get?

It depends on the content. Scanned and image-heavy PDFs often shrink 80-90%. PDFs that are already lean may not compress further — in that case everySIMPLEtool keeps your original instead of making it bigger.

Does compressing reduce quality?

Slightly, depending on the level you pick. "Recommended" keeps documents crisp and readable; "Extreme" trades more quality for the smallest size.

Why compress a PDF?

Smaller files send faster, fit under email attachment limits (usually 25 MB) and upload successfully to portals with strict size caps.
