Frequently asked questions
Will the watermark cover my content?
Lower the opacity so the watermark sits subtly behind your text — the live preview shows the exact effect before you apply it.
Can I use my brand color?
Yes. Pick from the swatches (including a neutral and a few common colors); the watermark uses your chosen color.
Is my file uploaded anywhere?
No. The watermark is applied entirely in your browser; your document never leaves your device.
