How to add a watermark to an image
Drop an image into the tool, choose Text watermark or Logo watermark, adjust the style and position, then select Apply Watermark. The preview updates locally while you edit.
How to watermark multiple images
Add several JPG, PNG or WebP files, set one shared watermark style, and choose Apply to All Images. Each source keeps its own dimensions while the watermark size and position use the same relative percentages.
Text watermark vs logo watermark
Text watermarks are useful for a name, copyright notice or draft label. Logo watermarks keep your brand artwork intact and support transparent PNG and sanitized SVG files.
How to choose watermark position and opacity
Use the nine-grid shortcuts for a consistent anchor, or drag the mark in the preview. Lower opacity protects the underlying image; a small edge margin keeps the mark visible without covering the subject.
Are images uploaded?
No. Files, logos, names and pixels stay in browser memory. Canvas performs decoding and encoding locally, and ZIP creation also happens on this device.
Which image formats are supported?
Images can be JPG, JPEG, PNG or WebP. Logo files can also be SVG. The output can keep the source format or be encoded as JPG, PNG or WebP.
