Watermark
Puts a visible caption with mahevi and today’s date on a photo and gives you the image back. For images you pass on that should show where they come from and when they were marked.
- JPEG · PNG · HEIC
- EXIF
Processed on the server
The image is uploaded to the mahevi server and processed there, not in your browser. The server keeps a copy of the result with a digital signature – including your photo’s metadata, the location too. So do not upload images that must stay private.
What goes onto the image
At the bottom centre, the caption “mahevi - YYYY-MM-DD” with today’s date, in semi-transparent white with a dark shadow, about 2% of the image height. A photo the camera stored rotated is turned upright first, so the text ends up at the bottom. The server also writes an identifier into the file’s EXIF comment.
Daily quota
How many watermarks you can set today is shown right above the upload. Without signing in it is fewer than with an account. Once today’s are used up, it works again the next day.
Set a watermark on an image
Click the box or drop an image onto it, the upload starts right away. You get back a JPEG under the original file name: it is downloaded and shown here with its metadata, with a map of where it was taken if it has GPS data. The switch below the image shows or hides the full list of metadata.
