FAQ
Is my data uploaded to a server?
No. Whenever possible, processing happens locally in your browser and we do not store your inputs or results on our servers. (Network requests may still occur for page loads and ads.)
Can conversion quality (fonts/layout/image quality) vary?
Yes. Results can vary by browser/OS, embedded fonts, source structure, and options (quality/resolution/compression). For important documents, always review the output.
My watermark is hard to read on dark or busy backgrounds. What can I do?
Turn on Auto Contrast, choose a brighter text color, and enable Stroke (outline). If it still looks faint, increase opacity or font size.
Should I download as JPG or PNG?
JPG is smaller but lossy. PNG keeps text sharper and preserves transparency. Use JPG for photos and smaller size; use PNG for crisp text or transparency.
