Frequently Asked Questions

Q: Do I need design skills to use this? A: Not at all! Watermark Image API is designed for non-technical users. Simply upload your images, choose your watermark settings from easy dropdowns, and let the tool do all the work. No Photoshop or design experience required.

Q: Can I watermark many images at once? A: Yes! You can upload multiple images or provide multiple image URLs, and the tool will process them all in one batch. This is perfect for photographers with hundreds of photos or e-commerce businesses with large product catalogs.

Q: What image formats are supported? A: For input, we support JPEG, PNG, and WebP formats. You can choose to output your watermarked images as JPEG (smaller files), PNG (transparency support), or WebP (modern web format).

Q: Will watermarking reduce my image quality? A: No! We use Sharp, a professional-grade image processing library that maintains the quality of your original images. You can choose quality settings for JPEG compression, and PNG outputs are lossless.

Q: Can I use both text and logo watermarks? A: Currently, you can use either a text watermark or a logo watermark in each run, not both simultaneously. This ensures clean, professional-looking results without cluttering your images.
