Preguntas frecuentes
Can I use my own text?⌄
Yes — type anything up to 60 characters, like "CONFIDENTIAL", "DRAFT", or a company name.
Does it cover the content underneath?⌄
No — the watermark is semi-transparent (you control the opacity), so the original content stays fully readable.
Is my file uploaded?⌄
No — the watermark is drawn entirely in your browser. Your PDF never leaves your device.
Can I remove a watermark added by this tool?⌄
Not with this tool — keep your original file if you might need an unwatermarked copy later.
