FAQ
Image Watermark Tool FAQ
Common questions answered about this free tool.
What watermark types are supported?
Text watermarks (customizable font, size, color) and image watermarks (upload your logo or signature as an overlay).
Can I adjust watermark opacity?
Yes. You can set opacity from 0-100%. Semi-transparent watermarks (30-50% opacity) protect images without completely obscuring them.
Are these image tools free to use?
Yes, all our image tools are completely free with no usage limits. You can compress, resize, convert, and edit images directly in your browser without uploading to any server.
Do you store my images on your servers?
No. All image processing happens entirely in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy and security.
What image formats are supported?
We support JPEG, PNG, WebP, GIF, BMP, and SVG formats for input. Output formats include JPEG, PNG, WebP, and PDF depending on the tool.
Is there a file size limit?
Since processing happens in your browser, the limit depends on your device's memory. Most modern browsers can handle images up to 50MB without issues.
What is the best format for web images?
WebP offers the best compression with quality, reducing file sizes by 25-35% compared to JPEG. PNG is best for images with transparency, and JPEG is universal for photographs.
Can I use these tools on mobile devices?
Yes, all our image tools work on mobile browsers. The Canvas API is fully supported on iOS Safari and Android Chrome.
What resolution should I use for social media?
Each platform has optimal sizes. Our social media image resizer provides preset dimensions for Instagram, Facebook, Twitter, LinkedIn, and YouTube.
How much can I compress an image without quality loss?
Lossless compression typically reduces file size by 15-25%. With minimal quality loss (90-95% quality), you can achieve 40-60% reduction. Our compressor lets you balance size and quality.
