How to add a watermark to images
- 1 Drop your photos on the box, or click browse to choose them. You can add many at once.
- 2 Choose Text or Logo, type your text or pick a logo file, then set position, size and opacity while watching the preview.
- 3 Press Watermark. One image downloads directly; several come in a ZIP file.
- 4 Check the new size and file size shown under each image.
Choosing a watermark style
A small corner mark suits portfolios and social posts, while a tiled mark suits previews you send to clients before payment. For a caption rather than a mark, use Add Text to Image. Before posting, remove hidden location details with Remove EXIF Data.
- Use a transparent PNG logo so only the logo shows.
- White text at around forty percent opacity works on most photos.
- Keep a clean, unmarked master copy of every photo.

Frequently asked questions
Where should I put a watermark?
A bottom corner is subtle and keeps the photo clean. For stronger protection, place it in the centre or tile it across the image so it cannot be cropped out easily.
What opacity is best?
Thirty to fifty percent is visible without spoiling the photo. Lower values are more discreet; higher values make copying harder.
Can I use my logo as a watermark?
Yes. Choose Logo and select an image file. A PNG with a transparent background looks best, because only the logo itself is placed on the photo.
Will the watermark stay the same size on different photos?
The size is set as a share of each photo's width, so it looks the same on large and small images and on portrait and landscape photos.
Can a watermark be removed by others?
Simple corner marks can be cropped or edited out. A tiled watermark across the whole picture is much harder to remove, although no watermark is impossible to defeat.
Does adding a watermark reduce quality?
The photo is saved again at high quality, so any change is very small. Keep your original files without watermarks for printing and future edits.
Can I watermark photos on my phone?
Yes. Open the page in your mobile browser, add photos from your gallery and download the watermarked copies.
Are my photos and logo uploaded?
No. The watermark is drawn onto your photos inside your browser, so neither the photos nor your logo are sent anywhere.
How this tool works. These image tools run entirely in your browser using the Canvas API built into every modern browser, the open-source libheif decoder for iPhone HEIC photos and Tesseract, a widely used open-source OCR engine, for reading text. Each tool is tested with real phone photos, screenshots and scans before it goes live, and nothing you open is sent to a server.
