Add watermark to image, without the upload.

Write a line of text on a picture, in a corner or across the middle. This adds a watermark; it does not remove one. Photos, scans and screenshots stay on your device.

How to add a watermark to an image

  1. Add your pictures

    Drop them above or choose them. The same mark goes on every picture.

  2. Type your mark

    Write the text, then pick the place, the size, the colour and how see-through it is. The button waits for some text.

  3. Add it and download

    Save each picture, or all of them as one .zip.

What stays and what doesn't

The mark is drawn into the pixels and the picture is saved again in the format it came in. These are the things that do not come along to it:

  • camera and capture details such as make, model and date taken
  • the GPS location
  • titles, authors, keywords and comments
  • the small preview stored inside the file
  • content credentials and edit history (C2PA)
  • the embedded colour profile (colours are changed to sRGB first; very saturated colours can look slightly flatter)
  • the stored print resolution
  • other data stored in or after the picture, such as a motion-photo clip, program-specific blocks or a modification time

A JPEG or WebP saved again loses a little detail.

When it won't run

Two things stop a run before it writes anything, and each is said on the file's row. A file that cannot be read is reported as damaged, and a picture too large for this device says so, with the limit. In both cases nothing is changed and your original stays as it was. A file in a format the page does not take, such as a GIF, gets a sentence instead of a row.

  • The picture is an animation. This tool would keep only the first frame, so it leaves the file alone.
  • The picture stores its colours as CMYK. This tool can't change it without altering the colours.
  • The picture stores 16 bits per colour. This tool works in 8 bits and would flatten it, so it leaves the file alone.
  • Type 1 to 64 letters, digits or marks, on one line.
  • Opacity runs from 5 to 100 percent.
  • That text can't be drawn with the font we have. Latin, Cyrillic, Greek and Vietnamese letters work.

Adding a watermark: what to expect

The mark is one line of text of 64 or fewer letters. You choose where it goes (the middle, slanted across the picture, or one of the four corners), how big it is (small, medium or large, as a share of the shorter side of the picture) and its colour, white or black. Opacity runs from 5 to 100 percent, and a low value lets the picture show through. A long mark is made smaller so that it fits, and is never cut.

This tool adds a watermark and never removes one. The text is drawn into the pixels, and once the picture is saved there is no layer to take it off again, so keep your original. A watermark discourages casual reuse. It does not stop someone who crops it out or paints over it, so do not treat it as protection.

Latin, Cyrillic, Greek and Vietnamese letters work. A letter the font does not have, or a right-to-left script, is refused with a sentence and nothing is drawn, rather than a box or a reversed word. A PNG or a WebP keeps its transparency. A JPEG or a lossy WebP is saved again at about the quality it had, and a PNG is written exactly.

The work happens in your device's memory: a JPEG or WebP of up to 40 megapixels and a PNG of up to 50 on a computer, and 16 megapixels of any format on a phone.

Questions

Are my pictures uploaded?

No. Your pictures are processed inside your browser, on your own phone or computer, and saved straight from this page. The reading at the top of the page counts every byte sent, and it stays at 0 B.

Can this remove a watermark?

No. It only adds one. Taking a mark off a picture means guessing what was underneath it, which this page does not do.

Can I use my logo?

Not here. This page writes text. A logo needs a picture laid over the first one, which is a different tool.

Which letters can I use?

Latin, Cyrillic, Greek and Vietnamese letters, with digits and common marks. Other scripts and right-to-left scripts are refused with a sentence that says so.

Will it still be there if someone crops the picture?

A mark in the middle is harder to crop out than one in a corner, and a slanted one across the picture is harder still. Anyone with time and an editing program can paint over any mark, so use one as a signal, not a lock.

Does it change the rest of the picture?

Only the pixels under the letters change. The rest is saved again in the same format: exactly for a PNG, and at about the original quality for a JPEG or a lossy WebP.
