Frequently asked questions
Is my PDF uploaded?
No. Compression runs locally in your browser.
Why can I no longer select text?
Each page is turned into an image to reduce its size, so text becomes part of the picture. Keep your original if you need searchable text.
Why is the result sometimes larger?
PDFs that are mostly text are already small. If the result is not smaller, keep the original or use a stronger level.
