Compressing PDFs: Online tool vs other methods
Shrink PDF size with in-browser compression, re-saving, or rasterizing pages—trade-offs for quality, speed, and text selectability.
Updated: 2026-05-08
Does compression always mean quality loss?
PDF size usually comes from images, so compression often involves some quality trade-off.
For email attachments, uploads, or archives, the right settings can still deliver big wins.
Alternatives: re-save and convert
Some apps offer “optimize” or “reduced size” exports—great results, but may require install or licensing.
Rasterizing heavy pages can shrink files a lot, but you may lose selectable text.
