Yes, we understand that consistency is key. While our tool respects your privacy by not requiring an account, the system utilizes your browser's local storage to remember your last used settings. This means that the next time you visit, your custom text, chosen font, uploaded logo, and opacity levels will automatically load for your next Custom JPG batch. This auto-save functionality ensures your brand remains perfectly consistent every single time you use the tool.
If your logo has an unwanted white background, it means the file you uploaded is likely a JPG. JPG files fundamentally do not support transparency, so any empty space is automatically filled with white. To fix this on your Custom JPG, you must ensure that your logo is saved and exported as a PNG file with transparency enabled. Once you upload a proper transparent PNG, our rendering engine will perfectly blend the logo onto your Custom JPG, removing the ugly white box entirely.
Because our tool processes everything locally, there are virtually no strict file size limits on your Custom JPG uploads. Unlike cloud-based tools that restrict you to 5MB or 10MB, our engine leverages your device's own hardware to render the watermark. This means you can easily watermark massive 4K raw exports, high-res panoramas, or large PDF manuals as long as your computer has the memory to handle it. For the absolute best performance on massive batches, we recommend closing unused browser tabs to ensure a smooth export.
Yes, combining text and graphics is a highly recommended way to create a comprehensive Custom JPG watermark. While our primary interface focuses on streamlined single-element application, you can easily apply your logo, save the file, and then quickly drop it back in to add text. Many professionals prefer to use a subtle transparent logo in the corner and a bold copyright text string across the center. This multi-layered approach ensures that even if one watermark is cropped out, the other remains for your creative Custom JPG assets.
When watermarking text-heavy documents, maintaining legibility is just as important as protecting the file. If your watermark is too dark, it will obscure the underlying paragraphs, which ruins the utility of the Custom JPG. We highly recommend setting the text opacity to around 10% to 20%. Additionally, placing the watermark diagonally across the page prevents easy removal while allowing the human eye to easily read the actual document text 'through' the watermark.
Yes, due to our advanced architecture. Because the entire watermarking engine is loaded into your browser, the actual processing does not require an active internet connection. If your Wi-Fi drops while batch processing a massive folder of Custom JPG files, the tool will continue to work flawlessly. Your files are processed using your local CPU, and the final ZIP download is generated directly on your hard drive, making this the most reliable and secure tool for off-grid or travel workflows.
