Free Online Image Watermark Tool - Add Text & Logo Watermarks

A Currently, our free online Image Watermark tool processes one image at a time to ensure optimal customization and performance for each photo. While batch watermarking isn't available right now, you can quickly apply your desired text or image watermark, then download and repeat the process for subsequent files. We are continuously improving our tool based on user feedback, and appreciate your suggestions.

A Yes, our free online Image Watermark tool provides full rotation control for both text and image watermarks. After adding your watermark, simply use the dedicated rotation slider or input field to adjust its angle. This allows you to place watermarks diagonally, along edges, or at any specific orientation, offering complete creative flexibility to effectively protect your photos or brand your visual content.

A Yes, our free online Image Watermark tool is designed to be fully responsive and works directly in your web browser across various devices, including smartphones and tablets. Since all processing happens locally, you can easily add text or image watermarks to your photos on the go, without needing to download any apps or compromise your privacy.

A Our free online Image Watermark tool makes it easy for small businesses to brand product photos. Upload your image, then select 'image watermark' and upload your logo. You can then adjust its size, position, opacity, and rotation directly on your product photo to ensure it complements your branding without obscuring details. This helps protect your intellectual property and promote your brand across e-commerce platforms and social media.

A You can upload common image formats like JPEG (.jpg) and PNG (.png) for watermarking. This covers most of the photos you'll be working with. If you're converting a screenshot from PNG to JPG, that works too. Just ensure the file is a standard web image.

A No hard limit exists. You can scale text up to fill the entire image if you want. The font size slider goes from 10px to 300px, but you can also type in a custom value. Just keep in mind that oversized text might look unprofessional. For product photos, I'd recommend keeping it between 40px and 80px for a clean brand mark.

A No, the original image stays untouched. The watermark is rendered on top during export, but the source file isn't altered. You can download at the same JPEG quality setting (default 90%) or switch to PNG for lossless output. For social media, JPEG at 80% quality keeps file size under 500KB while looking sharp. One tip: always keep a clean backup before watermarking.

A You need an internet connection to load the website initially, since it's a web app. But once the page is fully loaded, the browser can handle everything locally. If you disconnect your WiFi, the tool still works perfectly — all processing happens right in your browser's memory, not on a remote server. Great for coffee shops with spotty connections or when you're editing sensitive client files.

A Usually under 30 seconds, including upload and download. The actual processing is instant, since everything happens in your browser locally. Your computer's speed and image file size affect the export time. A 10MB JPEG exports in about 3 seconds on a modern laptop. For small business owners preparing marketing materials, that means you can watermark a dozen product photos in under 5 minutes. Tip: keep your browser updated for best performance.

A None whatsoever. Your images never leave your device. Every pixel stays inside your browser's memory, so there's no upload, no temporary file on a server, and no data leak. That's the entire point of local processing. Teachers handling student work or designers watermarking confidential drafts can use this tool without worrying about privacy. For extra peace of mind, close the browser tab after downloading your finished file.
