Frequently asked questions
Will compression hurt quality?
Compression aims to balance size and readability; documents stay legible, though heavily image-based PDFs may show some reduction in image detail.
Why is my PDF so large to begin with?
High-resolution scans and embedded images are the usual culprits. These are where compression yields the biggest savings.
Are my files uploaded?
No. Compression is performed locally in your browser, so your PDF stays on your device.
