FAQ
Q: Will watermarking reduce image quality?
A: Watermarking adds an overlay without compressing the original image. Quality remains intact. However, we recommend keeping unwatermarked originals for your archives.
Q: Can I remove watermarks later?
A: Once applied and saved, watermarks become part of the image and cannot be removed. Always keep original unwatermarked copies.
Q: What’s the best opacity for watermarks?
A: For subtle protection that doesn’t distract from the image, 20-40% opacity works well. For stronger branding, use 50-70%.
Q: Should I use text or image watermark?
A: Text watermarks are simpler and work well for personal use. Image watermarks (logos) look more professional for businesses and brands.
Q: Can I watermark multiple images at once?
A: Yes. Upload multiple images and apply the same watermark settings to all. Download them individually or as a batch.
Q: Is my image safe?
A: All processing happens locally in your browser. Your images are never uploaded to any server.
