Frequently Asked Questions
Is this watermark tool really free?
Yes, our watermark tool is completely free to use. No registration required, no watermarks on your output, and no hidden costs. All processing happens in your browser.
Do you store my images?
No. Your privacy is our priority. All processing is done in your browser using JavaScript - your images are never uploaded to our servers. Your files stay completely private.
How do I create a transparent watermark?
Use the opacity slider in our tool to make your watermark semi-transparent. For logos, we recommend uploading a PNG file with a transparent background for the best results.
What is the best format to save a watermarked image in?
If your original image has transparency, or you want the highest quality, choose PNG. For web use where file size is a concern, JPG is a great choice. WebP offers the best of both worlds.
Can I watermark multiple photos at once?
Currently, our free tool processes one image at a time. For batch watermarking of multiple images, we're working on a Pro version that will allow you to process entire folders at once.
What file formats are supported?
Our tool works with all common image formats including JPG, PNG, WebP, GIF, and more. You can output in PNG (best quality), JPG (smaller files), or WebP (modern format).
