Watermark Adder
Add a text or logo watermark to your photos — drag to position, adjust size and opacity. 100% private — runs in your browser, no server.
A watermark adder stamps text or a logo onto an image before you share it. Drag to place it, set size and opacity, and download at full original resolution —no upload, no sign-up, and no watermark of ours on your file. Photographers, designers and sellers use it to credit work and discourage casual reuse.
Text mode and logo mode
Text mode takes up to 60 characters with a colour picker, drawn in a bold system typeface. It is the right choice for a copyright line, a handle, a URL or a DRAFT / SAMPLE / CONFIDENTIAL stamp. White at reduced opacity works on most photographs; switch to a dark colour for images that are mostly light.
Logo mode composites any image file you choose. Use a PNG with a transparent background — whatever surrounds your logo is drawn too, so a logo saved on a white square arrives as a white square sitting on your photo. The logo keeps its own proportions, and its own transparency is combined with the opacity slider, so a semi-transparent PNG at 70% opacity ends up fainter still.
Placement, size and opacity
Drag anywhere on the image and the watermark centres on the point you release, starting near the bottom-right where photo credits usually sit. Size runs 5% to 60% and is measured against the image width, so the same setting produces a proportionally identical result on a 1000-pixel thumbnail and a 6000-pixel original. Opacity runs 10% to 100% in 5% steps.
| Goal | Size | Opacity | Placement |
|---|---|---|---|
| Discreet photo credit | 10–15% | 40–60% | A corner, inside the frame |
| Brand mark on social images | 15–25% | 70–90% | Consistent corner across the set |
| Deterring reuse of a proof | 40–60% | 25–40% | Centred, over the subject |
| DRAFT or SAMPLE stamp | 40–60% | 30–50% | Centred |
The pattern in that table is worth internalising: a corner watermark is a credit, not protection. Anyone can crop a corner in seconds. If the actual goal is to make an image unusable without permission, it has to sit over the subject where removing it damages the picture.
Preview versus output — one thing to know
Placement is accurate, but treat the preview's appearance as approximate. The on-screen overlay is drawn at a fixed screen size, while the exported file scales the watermark relative to your image's real pixel width, so the proportions shift a little between the two. The preview also adds a soft drop shadow for legibility that the exported file does not include — which matters most for white text on a pale photograph, where the preview can look perfectly readable and the download can look washed out.
The fix is simply to press Add watermark once and look at the result before committing to settings. It re-runs instantly and there is no limit on attempts.
What comes out the other end
The output keeps your exact original pixel dimensions — nothing is resized. The format matches what you put in: PNG stays PNG and keeps its alpha, WebP stays WebP, and everything else becomes JPG. Lossy formats are written at 92% quality, high enough that a second generation of compression is not visible at normal viewing sizes. One consequence worth flagging: a transparent PNG saved out as JPG gains a white background, because JPEG cannot store transparency.

What a watermark does and does not protect
A watermark is a deterrent and an attribution, not a legal mechanism. Copyright exists in your work whether or not you stamp it, and a watermark neither creates nor strengthens that right — what it does is make casual copying inconvenient and keep your name attached when an image travels. It is also removable: inpainting tools, including our own object and watermark remover, can take out a small corner mark convincingly. Placement over the subject is what actually raises the cost of removal.
Only watermark images you own or are licensed to distribute. Putting your mark on someone else's photograph does not transfer any rights and may well infringe theirs.

Removing a mark from your own image is the object and watermark remover, and PDFs are handled separately by add watermark to PDF. Before stamping, you may want to resize orcrop so the watermark sits correctly in the final frame, and after stamping the image compressor brings the file size down for upload. Stripping camera and GPS metadata before publishing is the EXIF remover — often a bigger privacy win than the watermark itself. Need a mark to stamp with? Thelogo maker produces a transparent PNG.
Frequently Asked Questions
How do I add a watermark to a photo online for free?
Choose a JPG, PNG or WebP image, pick Text or Logo mode, then drag anywhere on the preview to place the watermark. Set size and opacity with the two sliders, press Add watermark, and download. Nothing is uploaded and no watermark of ours is ever added to your file.Can I use my own logo instead of text?
Yes — switch to Logo image mode and choose any image file. A PNG with a transparent background works best, because whatever is behind your logo gets composited too, so a logo on a white square will show that square. The logo keeps its own aspect ratio and its own transparency.How do I position the watermark exactly?
Drag anywhere on the image and the watermark centres itself on the point you release. It starts near the bottom-right, the usual place for a photo credit. Because it is centred on that point, dragging right to the very edge will leave part of the watermark cropped off.Why does the watermark look different in the download than in the preview?
Position is accurate, but size and legibility are only indicative. The preview draws the text at a fixed screen size while the output scales it to your image’s real width, and the preview adds a subtle drop shadow that the exported file does not have. Apply once and check the result before settling on your settings.What size and opacity should I use?
Size runs from 5% to 60% of image width and opacity from 10% to 100%, defaulting to 20% and 70%. For a discreet credit, 10–15% size at 40–60% opacity reads clearly without dominating. For deterring reuse of a preview image, go larger and more central — a corner mark is trivially cropped out.Can I watermark several photos at once?
Not here — it is one image at a time, which is the trade for being able to drag the placement and judge the result on each photo. For a whole shoot you would want desktop software or a script, since a per-image drag is the point of this tool rather than a limitation to work around.Does watermarking reduce image quality or change the size?
The output keeps the original pixel dimensions exactly. The watermark is composited onto a full-resolution canvas and re-encoded in the same format you supplied, at 92% quality for JPG and WebP and lossless for PNG. A transparent PNG saved as JPG will gain a white background, as JPEG has no alpha channel.Is my photo uploaded anywhere?
No. The image, your logo file and the finished composite all stay inside the browser tab — the watermark is drawn with the Canvas API and handed to you as a local download. Nothing is transmitted, stored or logged, and the page keeps working offline once loaded.
