Add a watermark to your photos
Import images, choose text or a logo, then adjust opacity, size, rotation and position. Tiling repeats the watermark across the image. Compare the preview with the original before exporting.
Free, with no account required
Process up to 20 images per batch, with limits of 20 MB and 24 megapixels per image, and 80 megapixels per batch. These limits protect browser memory; a less powerful phone may require a smaller batch.
Your files stay on your device
Photos, logos and text are processed in your browser and are not sent to Outilo. Only display and export settings are saved locally, without your text or files. The reset button removes these preferences. Content-free usage events are sent only with your analytics consent.
Export one image or a batch
Choose PNG, JPG or WebP. Pixel dimensions are preserved; images are re-encoded and original metadata is not copied. JPG may affect quality and replaces transparency with white. Multiple images are bundled in a ZIP archive.
A watermark helps identify your work but cannot guarantee that an image will not be copied or edited. Keep your originals: this tool creates new files without modifying the files on your device.
FAQ
Is it free without signing up ?

Are my photos sent to a server?
No. Processing and exports take place on your device. The tool does not send your photos, logo, filenames or text.
Which settings are saved?
Watermark type, font, colour, opacity, size, rotation, margin, position, tiling and format. Neither text nor files are saved. Reset settings to remove these preferences from this browser.
What are the batch limits?
Up to 20 images, 20 MB and 24 megapixels per image, and 80 megapixels per batch. On a less powerful device, start with a few images.
Is the original quality preserved?
Pixel dimensions are preserved, but the image is re-encoded. JPG and WebP may affect its quality. PNG is suitable for transparency. Original metadata is not copied.
Does a watermark prevent copying?
No. It helps identify an image and may discourage reuse, but it can be cropped or edited. Always keep your original files.
