Free Online Image Watermark Tool – Protect Your Photos in Seconds
The Image Watermark tool from ConvertFree.net helps photographers, designers, agencies and content creators protect their work with a clear text watermark. Instead of opening a heavy desktop editor every time you share new photos, you can upload a batch of JPG or PNG images, type your brand name or URL and apply the watermark to all of them in a single click. It’s a fast way to keep your visual content attributed, even when it travels across websites, social media and messaging apps.
All processing happens directly on our server through the Imagick engine. Your images are never sent to external conversion APIs, which keeps the workflow private and predictable. You can choose the watermark position (bottom-right, corners or center), adjust the font size and control opacity, so the text is visible without completely blocking the underlying photo. The tool uses a combination of light text and subtle outline to stay readable on most backgrounds.
When you upload a single image, you’ll receive a direct watermarked file ready to download. When you upload multiple pictures, the tool processes each one and bundles all results into a ZIP archive, so you can protect an entire shoot, product catalog or portfolio page in one go. Filenames are cleaned and tagged with “-watermarked” so you can keep original and protected versions side by side in your folders or DAM (digital asset management) system.
This watermark tool fits nicely with other utilities on ConvertFree.net. You can first prepare images with the Image Resizer to reduce dimensions for web, then apply your watermark text here. If you need to convert formats before or after watermarking, use JPG to PNG or PNG to JPG. For document workflows, you can export pages with PDF to JPG or PDF to PNG, protect those images with watermarks and then rebuild everything as a shareable document using JPG to PDF or PNG to PDF.
ConvertFree.net is designed with clean HTML, fast loading and a layout that works well with Google AdSense guidelines. There are no watermarks from us, no forced login and no confusing menus – just a simple, reliable image watermark tool that you can bookmark and use any time you want to protect your photos before posting or sending them to clients.
Image Watermark Tool – Frequently Asked Questions
How do I add a watermark to my images on ConvertFree.net?
Upload one or more JPG/PNG images, enter the watermark text, choose a position, font size and opacity, then click “Apply watermark to images”. The tool processes each file on our servers and gives you either a single download or a ZIP archive containing all watermarked images.
Can I watermark multiple images at once?
Yes. You can upload a whole batch of photos or graphics. The same watermark settings are applied to every image, and when there is more than one result, the tool bundles everything into a ZIP file so you can download all watermarked images in one click.
Which image formats are supported for watermarking?
The Image Watermark tool currently supports JPG/JPEG and PNG files. If you start from other formats or documents, you can convert them first using tools like PDF to JPG, PDF to PNG, JPG to PNG or PNG to JPG, then apply your watermark here.
Will the watermark affect the quality of my images?
The watermark is drawn directly onto each image using a balanced quality setting. JPG images are recompressed at a high-quality level, and PNG images stay in PNG format. There may be a small change in file size, but visual quality remains suitable for web, social media and everyday client use.
Are my images safe and deleted automatically?
Yes. Your files are processed only on ConvertFree.net servers and are not sent to third-party conversion APIs. An automated cleanup routine regularly removes old uploads and watermarked results from our storage folders, so your content is not kept longer than necessary.
