What this tool doesAdd Logo to Image overlays a brand logo, badge, watermark, or signature on top of a photo and exports a flattened copy. Position, size, opacity, margin, and rotation are tuned with live preview, so you can compare layouts in seconds before downloading.
Why use a logo overlayBranding photos before publishing protects authorship, reinforces identity on social posts and product shots, and keeps marketing assets consistent. A clean PNG logo with transparency takes a couple of seconds per image — far faster than reopening a desktop editor for each photo.
Step-by-step1. Upload a photo (JPG, PNG, WebP, GIF, or BMP up to 20 MB). 2. Upload a transparent PNG or WebP logo up to 5 MB. 3. Pick a corner from the 3×3 position grid or a quick preset, then fine-tune Size, Opacity, and Margin. 4. Choose JPG, PNG, or WebP and download.
Tuning the lookUse 60–80% opacity for photos so the subject stays primary. Drop Size to 8–12% for subtle signatures and lift to 25–35% for prominent branding on banners. Increase Margin when the logo touches important edges of the composition.

Interface walkthroughUpload Image — drop a photo or click to browse. The card shows the resolution and file size so you can confirm the right asset was loaded.
Upload Logo — pick a transparent PNG or WebP. A checkerboard preview makes alpha edges visible before compositing.
Position grid — nine anchors map to corners, mid-edges, and center. The Quick Presets row mirrors the four corners and Center for one-click placement.
Size / Opacity / Margin — Size is a percent of photo width, Opacity controls the logo's alpha, and Margin is the pixel distance from the chosen edge.
Advanced Settings — open this for Rotation if you need a tilted stamp or diagonal watermark.
Output — JPG flattens transparency to white and respects Quality, PNG keeps transparency lossless, WebP supports both with the smallest files.
