Add a Logo Watermark to Images
Overlay your logo on photos with position, scale and opacity control. Perfect transparent PNG logo support.
About the Logo Watermark
Brand every photo with your logo. Transparent PNG logos overlay beautifully at any scale; the margin control keeps them safely inside the frame. Upload your photos, pick a logo from the file slot, and batch-brand up to 10 images.
How it works
Your logo (ideally a transparent PNG) is composited over each photo at a scale relative to image width, with independent opacity, margin and one of nine position anchors. Because compositing happens per image, the same settings produce consistent branding across a whole batch.
How to use it
Drop your photos, add the logo file in the watermark section, set scale and opacity (20–35% keeps photos readable), pick a corner with a sensible margin, then process and download.
Supported formats & limitations
Accepts .jpg, .png and .webp photos up to 30MB each, 10 per batch; the logo itself loads as a separate file. Transparent PNG logos composite cleanly — opaque logos bring their own background rectangle, so export yours with alpha.
Common use cases
Photographers protecting portfolio shots, stores branding listing photos, agencies watermarking campaign previews, and teachers marking handout imagery. One settings pass brands up to ten photos identically.
Frequently asked questions
Where are my images processed?
Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.
Can it open JPG, PNG and WebP files?
The common formats are covered — JPG, PNG or WEBP, each up to 30 MB. Queue them one batch at a time.
How many images can I process at once?
Batch runs take up to 10 files at once (30 MB each). There's no account, no daily quota and no watermark — process as many batches as you need.
Can I fine-tune the result before downloading?
Yes — settings include Logo file (PNG recommended), Logo width and 3 more controls. Each run regenerates the preview, so you can compare options before downloading.
