Frequently asked questions
What's the difference between the levels?
Lossless optimizes the file structure and keeps everything exactly the same. Recommended and Strong turn pages into optimized images for much smaller files, but the text can no longer be selected.
What if the file doesn't get smaller?
Some PDFs are already optimized. In that case we keep your original and tell you.
Are my files uploaded to a server?
No. All processing happens in your browser on your own device. Your files never leave your computer or phone, which makes PDFwise safe for confidential documents.
