Stamp your name, brand or copyright onto any photo with adjustable opacity, size and position — or tile it across the whole image. Everything runs in your browser.
Add one or many — PNG, JPG & WebP. Or paste with ⌘/Ctrl + V
Type your text or pick a logo image, choose one of nine positions or tile it diagonally across the photo, and set opacity (10–100%) and size (2–12% of the image width). Click Apply and the watermark is drawn straight into the pixels — locally, with nothing uploaded.
Clean the Gemini sparkle, then finish the job — crop, resize, convert and adjust without uploading a single pixel.
Reverse-alpha math restores the true pixels under the Gemini logo — no blur, no AI guesswork.
Crop to any aspect ratio with draggable handles, then resize to exact pixels or quick scales.
Export to PNG, JPG or WebP with a quality slider and a live file-size estimate.
Every tool runs locally with undo/redo. Nothing is uploaded — it even works offline.
Text or logo, positioned or tiled — your call.
Open the Watermark tool and type your text (e.g. "© Your brand") — or switch to Logo and pick an image file, ideally a transparent PNG.
Click a cell on the 3×3 position grid or flip on "Tile across image" for a diagonal repeat. Dial in Opacity (10–100%) and Size (2–12% of the image width).
Click Apply — the watermark is stamped into the image — then download as PNG, JPG or WebP. Undo removes it instantly if you change your mind.
Send clients tiled, low-opacity proofs so images can be reviewed but not used before payment.
A small corner handle or brand name that travels with your image when it gets reshared.
Stamp your shop name on listing photos so competitors can't lift them straight into their own listings.
Mark concept art, designs and drafts with a logo watermark while keeping the piece viewable.
Tile CONFIDENTIAL or DRAFT diagonally across a page image so the status is impossible to miss — or crop out.
Everything about adding watermarks with PixKit.
PixKit adds a text watermark to your images entirely in your browser. Type your text, choose the opacity and font size, and place it in any of nine positions — or switch to tiled mode to repeat it diagonally across the whole picture so it can’t be cropped out. The watermark is drawn with a translucent white fill and a subtle dark shadow so it stays legible on both light and dark backgrounds.
Alongside text, a Logo mode stamps an image of your choosing — a brand mark, signature PNG or icon. Pick the file, and the same position grid, opacity slider and tiling switch apply to it; a transparent PNG logo composites cleanly over any photo.
A relative font size (2–12% of the image width) means your watermark scales correctly whether the image is a tiny thumbnail or a full-resolution export. Opacity runs from a faint 10% hint up to a bold 100% stamp, and the 3×3 position grid lets you tuck it into a corner or center it dead-on. Tiled mode rotates the repeats diagonally, covering the frame edge to edge.
Your images are never uploaded — the watermarking runs 100% locally and keeps working offline. There are no accounts, no usage limits, and no watermark-of-the-tool added to your output. Apply, undo, and re-apply as many times as you like, then export as PNG, JPG or WebP.
