Bulk image watermark tool
Build your branded batch
Everything happens locally. Large batches depend only on your device's available memory.
01 Upload your logo
03 Add your images
04 Preview and download
Add an image to check placement before exporting.
Consistent by default
Set the treatment once. Apply it everywhere.
Every image in your batch uses the same logo settings, so a product launch, property listing, or client proof stays visually consistent.
- Position
- Choose any of the four corners.
- Size
- Scale the logo from subtle to prominent.
- Edge spacing
- Keep a controlled margin from the image edges.
- Opacity
- Use a solid brand mark or a softer watermark.
Privacy by architecture
Your image files stay in your browser.
LogoMatic processes the images you select locally on your device. The tool does not upload those image files to a LogoMatic server for editing.
Temporary browser URLs are used to show previews while the page is open. Your original files are not changed; PNG sources remain PNG and other supported sources export as JPEG copies.

Quick answers

Direct answers about privacy, supported files, editing controls, and downloads.
What is LogoMatic?
LogoMatic is a free browser-based tool for adding a logo or watermark to multiple images in one batch. You can choose the logo position, size, padding, and opacity before downloading the processed images.
How much does it cost?
LogoMatic is free to use. There is no paid tier and no email address is required.
Do I need to create an account?
No. You can use LogoMatic without creating an account or signing in.
Are my images uploaded to a server?
No. LogoMatic reads and processes the image and logo files locally in your browser. Your selected image files are not uploaded to LogoMatic for processing.
Does LogoMatic store my images?
No. LogoMatic does not send or store the image files you select. Temporary browser URLs and processed image data are used in the open page so you can preview and download your results.
Does LogoMatic use analytics?
LogoMatic may use Google Analytics when analytics is configured by the site operator. Analytics can record general usage information, but your selected image files are processed locally and are not sent to Google Analytics.
What image formats are supported?
LogoMatic accepts JPG, JPEG, PNG, HEIC, and HEIF files for both the logo and source images. PNG results stay PNG; other inputs are converted to JPEG before or during editing.
How many images can I process at once?
LogoMatic does not set a fixed batch limit. The practical limit depends on your device memory, image dimensions, and browser. Smaller batches are more reliable for very large photos.
Can I adjust the logo position and size?
Yes. Place the logo in the top-left, top-right, bottom-left, or bottom-right corner. You can also adjust its size, edge padding, and opacity.
What happens to the original images?
Your original files are not modified. LogoMatic creates processed copies for you to download.
How does the processing work?
LogoMatic decodes each selected file, resizes and positions the logo, composites it onto the image, and generates a PNG or JPEG result locally in your browser.
