Frequently asked questions
How many files can I process at once?
No limit — everything happens locally in your browser. Many large files may take a moment.
How much is saved?
It varies per PDF. Simple documents can shrink significantly. PDFs with many images or already-optimised files shrink less.
Are my files uploaded?
No. Everything happens in your own browser. Your file never leaves your device and is not stored anywhere.
Is it free?
Yes, completely free and without watermark, ads or account.
