Yes, our platform is 100% cross-platform compatible. Because it is a progressive web application, it does not matter if you are using macOS, Windows 11, Linux, or ChromeOS. As long as you have a modern web browser, you can instantly access and utilize our Custom JPG watermarking engine. There are no executable files to download, no drivers to update, and no compatibility issues. Just open the page and start protecting your files.
Handling mixed file sizes in a batch is a common challenge. If you use absolute pixel sizing (e.g., exactly 300px wide), a watermark might look huge on a low-res image and microscopic on a 4K photo. To solve this, our Custom JPG tool uses relative scaling. When you set your watermark to cover 20% of the image width, the system intelligently resizes the stamp for every single file in the batch. This ensures your Custom JPG watermark looks perfectly proportional across all resolutions.
You absolutely do not have to save them individually. When you finish processing a batch of Custom JPG files, our engine compiles everything into a single, highly compressed ZIP archive. With just one click, you can save hundreds of protected files to your hard drive instantly. This ZIP generation happens locally in your browser, meaning it is blazingly fast and completely private. You can then simply extract the folder and your protected documents are ready for immediate publishing or client delivery.
For legal and corporate watermarks on your Custom JPG, clarity and legibility are far more important than artistic flair. We highly recommend using clean, geometric sans-serifs like Helvetica, Arial, Roboto, or Montserrat. These fonts scale beautifully even when subjected to heavy JPEG compression or small screen sizes. Avoid using highly decorative script fonts, grunge typography, or overly thin weights, as they can become completely unreadable when the opacity is lowered, defeating the purpose of the watermark.
Yes, our tool is 100% free for both personal and commercial use. Whether you are a freelance photographer protecting client proofs or an e-commerce store batch-processing product listings, you can use our Custom JPG watermarker entirely for free. We do not inject any of our own promotional branding into your files, ensuring your output looks completely professional and bespoke. Our mission is to provide enterprise-grade digital security tools to everyone, regardless of their business size or budget.
Our tool is strictly designed for applying watermarks, not removing them. In fact, removing a legitimate copyright watermark from a Custom JPG is a direct violation of copyright law in most jurisdictions. A properly applied watermark, especially one that is tiled or placed over complex details is mathematically baked into the image pixels, making it incredibly difficult to remove without leaving obvious, ugly smudges. If you made a mistake on your own file, you should always return to your original, unwatermarked master file rather than trying to digitally erase the stamp.
