Watermark Tool

Text and logo marks without upload

01

Text and logo layers

Stack a copyright line and a PNG, JPEG, or WebP logo. Edit each layer’s size, opacity, and rotation independently.

02

Single mark or tiled repeat

Place one mark, or tile it across the photo with adjustable X/Y spacing — including diagonal repeats for proof copies.

03

Ready-made templates

Start from corner, center, diagonal, dense, brand, or subtle presets, then tweak the selected layer.

04

Local export, no upload

Rendering uses the Canvas API in this browser. Download PNG, JPEG, or WebP — the source photo is not sent to a server.

How it works

Four short steps

01Upload a photo

Drop a PNG, JPEG, or WebP. The preview canvas stays on this device.

02Add text or a logo

Insert a text layer or a logo image. You can keep both on the same photo.

03Position and tile

Drag, resize, set opacity, rotate, or switch to repeat mode and adjust spacing.

04Export

Choose PNG, JPEG, or WebP and download the watermarked file.

FAQ

Questions answered

How text, logo, and tiled watermarks work in the browser.

Yes. Add as many text and logo layers as you need, then select one to edit size, opacity, rotation, and repeat.

Switch a layer to Repeat, then set spacing X/Y and rotation. Diagonal and dense templates are a quick start for proof or public previews.

No. Watermark compositing runs in your browser. ImgSplit never receives the image or the logo.

PNG, JPEG, and WebP. JPEG and WebP include a quality control; PNG keeps transparency around the canvas.
