Frequently Asked Questions

How does PDF compression work?▼

PDF compression reduces file size by re-encoding embedded images at a lower quality and stripping metadata. Text and vector graphics remain sharp.

Will compression affect PDF quality?▼

At medium compression, the visual difference is imperceptible for most documents. High compression may show slight artifacts in photographs.

Is my PDF uploaded to a server?▼

No — compression happens entirely in your browser. Your files never leave your device.
