Don’t take our word for it: after loading your files you can even disconnect from the internet and the tool keeps working. How we handle your files
Click Choose logo and select your logo file. A PNG with transparency gives the cleanest edges.
Logo on a white background? Tick Make white background transparent.
Add the images you want to brand — one or hundreds.
Set the logo size (as a % of each image’s width), opacity and position. Bottom-right with a 3% margin is a safe default; 100% opacity gives a solid logo, 60–80% a subtle watermark.
Click Add watermark and download.
Logo or watermark? Same tool, two looks
A logo overlay is usually small, fully opaque and in a corner — branding for social media posts, product photos, real-estate listings or YouTube thumbnails. A logo watermark is larger, semi-transparent and often centred or tiled — protection for previews and proofs. Both use the same settings here: just change size, opacity and position. Need it on documents? Use Add logo to PDF.
Best practices for putting your logo on photos
Use a white or light version of your logo for dark photos and a dark version for bright ones; a white logo with a soft edge works on most images.
Keep it proportional: 12–20% of the image width is enough for branding.
Consistency: use Pixels mode to place your logo at exactly the same distance from the corner on every image of a series, or Percentage mode for mixed sizes and orientations.
Save your settings: tick “Remember my settings” so next time you only need to load the logo and your photos.
Frequently asked questions
How do I add a logo to a picture for free?
Choose your logo with “Choose logo”, add your pictures, pick a corner and size, and click “Add watermark”. Free, no account.
What file format should my logo be?
A PNG with a transparent background is ideal. JPG, WebP and SVG also work; for JPG logos on white, enable the white-removal option.
Can I add a logo to many photos at once?
Yes. Upload the logo once, add all your photos and the logo is applied to every one of them. Download them as a ZIP.
Do you keep a copy of my logo or photos?
No. Your logo and photos are processed in your browser and never uploaded or stored on our servers.
