Frequently Asked Questions
Is this watermark tool free?
Yes, completely free. There are no sign-ups, no limits, and no hidden fees. All processing runs inside your browser.
Can I watermark multiple images at once?
Yes. Select or drop multiple image files at once. Click "Download" and all images are processed with your current settings and packaged into a single ZIP file.
What is tile mode?
Tile mode repeats your watermark across the entire image in a grid pattern. You can control horizontal and vertical spacing, and optionally stagger alternate rows — ideal for copyright protection.
Does it support transparent PNG logos?
Yes. Upload any PNG with a transparent background as your logo watermark. The transparency is fully preserved when applied to your photos.
Will my images lose quality?
If you export as PNG, there is no quality loss. For JPG and WebP, set the quality slider to 90–100% to minimize compression artifacts.
Are my images uploaded to a server?
No. This tool is 100% client-side. Your images are processed entirely within your browser using the Canvas API and are never transmitted anywhere.
