Frequently asked questions
What is the difference between Basic and Strong compression?
Basic cleans up and optimises the PDF structure and keeps text selectable. Strong turns each page into an optimised image, which makes scanned and image-heavy PDFs much smaller, but text can no longer be selected.
Why did my PDF not get smaller?
Some PDFs are already well optimised. Try Strong compression, or a lower quality setting.
Are my files uploaded to your server?
No. Everything happens inside your browser, so your files never leave your device. That also makes it fast.
