Why watermark your photos?
If you are a photographer, artist, online seller or content creator, your photos can be copied and reposted within minutes of going online. A watermark puts your name on the image, so credit follows the photo wherever it is shared.
This tool processes everything locally. Many online watermark makers ask you to upload your full-resolution photos to their servers. Here the watermark is drawn in your browser with the HTML5 Canvas, so your photos stay on your device and large batches do not wait on an upload.
Need to shrink the files before posting? Use the image compressor or the image resizer after watermarking. If you need to clean a watermark from your own photo or an old export, try the image watermark remover, which is meant for your own or permitted content only.
Features of this free watermark maker
Discourage copying
A visible watermark with your name or brand makes it harder for others to reuse your photos without credit.
Batch watermarking
Add the same watermark to up to 20 images at once instead of editing each photo by hand.
Private, runs in your browser
Your photos are not uploaded to a server. The watermark is drawn in your browser using the HTML5 Canvas API.
Full control
Change text, size, color, opacity, rotation and position. Tiled mode repeats the text across the whole photo.
Watermark tips: opacity, position and text
A good watermark is visible but does not spoil the photo. These settings work well for most images.
- 1
Keep opacity between 30% and 60%
A semi-transparent watermark is easy to read but does not hide the subject of your photo.
- 2
Use tiled mode for stronger protection
A mark in a plain corner is easy to crop out. Tiled mode repeats it across the whole image, which is much harder to remove.
- 3
Use your name or brand, not a long sentence
Short text such as your name, studio or website stays readable at small sizes and on phones.
- 4
Choose a color with contrast
White works on dark photos and black or dark gray works on bright photos. A slight rotation also helps the mark stand out.
- 5
Watermark copies, keep originals
Always keep your original, unmarked photos safe and publish only the watermarked copies.
Who uses an online image watermarker
Photographers
Share previews and portfolio shots online with your name on them before the client pays for the full-resolution files.
Online sellers
Put your shop name on product photos so competitors cannot reuse them in their listings.
Artists and designers
Post your artwork on social media with a visible credit that travels with the image.
Real estate and events
Mark property or event photos with your agency or studio name before sharing them publicly.
Content creators
Add your handle to photos and graphics so people can find you when your content is shared.
Proofs and drafts
Mark images as DRAFT or PROOF so nobody mistakes an unfinished image for the final one.
What works well and what to keep in mind
What works well
- Text watermarks on JPG, PNG and WebP photos, up to 20 per batch
- Full original resolution is kept, only the watermark is drawn on top
- Tiled mode makes cropping the mark out much harder
- Same settings applied to every photo, with size relative to image width
What to keep in mind
- Text only for now. Logo or image watermarks are not supported yet
- JPG and WebP are saved as JPG, PNG stays PNG. JPG applies standard compression
- A watermark discourages casual copying but cannot stop a determined editor
- Very large photos or low-memory phones may need smaller batches

Watermark tool FAQ
How do I add a watermark to a photo online for free?
Upload your photo with the tool above, type your watermark text, choose the size, opacity and position, then download the result. There is no sign-up and no cost.
How do I add a watermark to multiple photos at once?
Upload several images together (up to 20 at a time), set your watermark once, and download. The tool processes every image and gives you a ZIP file.
Is this watermark tool free?
Yes. It is free to use with no sign-up and no watermark added by us.
Does it upload my photos to a server?
No. Everything runs locally in your browser using JavaScript, so your images stay on your device.
Can I adjust the transparency of the watermark?
Yes. Use the opacity control to make the watermark semi-transparent. This protects the image without ruining how it looks.
What image formats are supported?
You can upload JPG, PNG and WebP images. JPG and WebP photos are saved as high-quality JPG files and PNG photos stay PNG.
Does watermarking reduce image quality?
The watermark is drawn onto the full-resolution pixels in your browser, so the image keeps its original dimensions. Saving as JPG applies standard JPG compression.
Can I use a logo or image as a watermark?
Not yet. This tool currently supports text watermarks only.
Will a watermark stop people from stealing my photos?
A watermark discourages casual copying and gives you credit when the photo is shared, but it cannot stop a determined person from editing it out. Use it together with lower-resolution previews and keep your originals private.
What is the best watermark opacity and position?
Most people use 30% to 60% opacity. For stronger protection use tiled mode or place the text over the main subject, since corner marks are easy to crop out.
How do I add a copyright symbol to my watermark?
Type or paste the © symbol in the watermark text box, for example "© Your Name". On Windows press Alt+0169, on Mac press Option+G.
How do I move the watermark to an exact spot?
Drag the text on the live preview with your mouse or finger. Keyboard users can focus the preview and use the arrow keys. Choose Custom position to keep it where you placed it.
