Add Watermark to Image Online Free
Watermarking protects your images from unauthorised use, establishes attribution, and helps viewers track your work back to its source. Whether you are a photographer sharing portfolio images online, a designer sending proofs to clients, or a business branding product photos, the free watermark tool on PublicSoftTools adds text or logo watermarks directly in your browser — no upload, no account.
How to Add a Watermark to an Image
- Open the watermark image tool.
- Upload your image (JPEG, PNG, WebP, GIF supported).
- Choose watermark type: text (type your name, website, or copyright notice) or logo (upload a PNG with transparency).
- Set position: bottom right, bottom left, centre, diagonal, or tiled.
- Adjust opacity (30–50% is typical — visible but not overwhelming).
- For text: set font, size, and colour.
- Preview the watermarked image, then click Download.
Watermark Position Options
| Position | Use | Removal risk | Best for |
|---|---|---|---|
| Bottom right | Most common; unobtrusive for viewers while clearly visible | Easiest to crop out if image has generous borders; move to centre for high-value content | Photography portfolios, stock images, product photos |
| Bottom left | Alternative to bottom right; less expected crop position | Still croppable; same limitations as bottom right | When subject occupies right side of frame |
| Centred (opaque) | Maximum protection; prevents removal without destroying the image | Obstructs the image significantly; affects viewer experience | Proof images sent to clients before final delivery; preview watermarks on high-value content |
| Tiled (repeated) | Covers entire image with repeated watermarks; hardest to remove | Heavily obtrusive; typically used only when protection is critical | High-value artwork; images with significant removal risk; commercial preview galleries |
| Diagonal centre | Covers both portrait and landscape compositions; harder to crop | Obstructs middle of image; may be acceptable with low opacity (20–30%) | When bottom corners are part of the composition; architectural or landscape photography |
Types of Watermarks
| Watermark type | Examples | Pros | Cons | Best for |
|---|---|---|---|---|
| Text watermark (simple) | © [Your Name] 2026, @yourusername, yoursite.com | No separate file needed; easy to create; clear attribution | Can be edited or cloned out with Photoshop; name could be changed | Social media photography; blog images; moderate protection needed |
| Logo watermark (PNG with transparency) | Your business logo, stylised signature, brand mark | Branded; more recognisable; transparent PNG blends naturally with image | Requires a logo PNG file; still removable from image corners | Professional photographers; brand content; portfolio images |
| Combined text + logo | Logo above with business name below | Maximum brand recognition; harder to remove than single element | More prominent; takes up more image space | Commercial photography; stock image licensing; high-value work |
| Steganographic (invisible) | Hidden metadata or pixel-level encoding | Does not affect image appearance; can track unauthorised use | Requires specialist software; not supported by most basic tools; watermark may not survive JPEG compression | Professional photographers tracking licensing; high-value commercial content |
Watermark Opacity: Finding the Right Balance
Opacity is the key tension in watermarking — too transparent and it doesn't deter theft; too opaque and it ruins the viewing experience:
- 10–20% opacity: Barely visible; used when brand presence matters but content must remain fully viewable. Low protection value.
- 30–50% opacity: The sweet spot for most portfolio and social media use. Clearly visible but not distracting from the image. Can be removed by a determined person with Photoshop but deters casual theft.
- 60–80% opacity: High visibility; used for proof images sent to clients before payment. Image is usable at preview resolution but clearly marked.
- 100% opacity: Fully opaque watermark; maximum visibility. Used for proof watermarks that deliberately obstruct the image to prevent use before payment.
Watermarking for Photographers
Photography watermarking involves specific considerations:
- Before sharing proofs: A prominent centre watermark on proof images allows clients to review composition while preventing free use of the final image. After payment, deliver the unwatermarked file.
- Portfolio and social media: A subtle bottom-right watermark with your name and website increases discoverability when images are shared without credit. Someone who sees your work on Pinterest and is interested can find you.
- Consistent positioning: Use the same watermark style and position across your portfolio for consistent branding. A watermark that becomes recognisable trains viewers to associate the style with you.
- Keep the original unwatermarked: Always keep a clean master file. The watermarked version is a derivative for sharing; the original is your asset.
- EXIF metadata: In addition to visible watermarking, embed copyright information in EXIF metadata (creator, copyright, website). Many reverse image search tools and stock image platforms use this data. Lightroom and Photoshop can embed EXIF automatically.
Legal Protection: What a Watermark Does and Does Not Do
A watermark is a deterrent and attribution tool — it is not a legal barrier to copying. Understanding the actual protection:
- Copyright is automatic: In the UK (and most countries), copyright in a photograph belongs to the creator the moment it is created — you do not need to watermark, register, or publish it to have copyright. A watermark makes enforcement easier (proving attribution) but does not create copyright.
- Removal of watermarks is illegal: Under the Copyright, Designs and Patents Act 1988, removing a watermark or copyright notice from an image is a criminal offence in the UK, separate from the underlying copyright infringement.
- Reverse image search: Register your work with Google Image Search by ensuring your images are indexed. If your watermarked image appears elsewhere, reverse image search can find unauthorised uses.
- Enforcement: For commercial infringement (someone selling prints of your watermarked photo), a letter before action often resolves the issue. Persistent or commercial infringement can be pursued through the Copyright Tribunal or court. Many photographers use image licensing platforms to simplify enforcement.
Common Questions
Can a watermark be removed?
Yes — with image editing software, a corner watermark can often be removed by cropping, cloning, or AI-based inpainting (Adobe Firefly, Photoshop Generative Fill can remove watermarks from simple backgrounds). This is why corner-only watermarks provide limited protection against motivated infringers. Tiled watermarks across the full image are significantly harder to remove convincingly. The goal of most watermarks is to deter casual copying and ensure attribution when legitimately shared — not to create an unbreakable technical barrier.
Should I watermark images before or after editing?
Always watermark after editing is complete, and apply the watermark to a copy (not the original). Watermarks are added to the final export file for sharing, not to the working file. Keep original editable files (RAW, PSD, TIFF) clean for client delivery, further editing, or licensing. Only the distribution copy (web-optimised JPEG, PNG) should have the watermark.
What text should I use for a copyright watermark?
The standard copyright notice format is: © [Year] [Your Name or Business Name]. Example: © 2026 Jane Smith Photography. You can also include your website (© 2026 janesmith.co.uk) or social media handle (@janesmith). The © symbol is sufficient in all Berne Convention countries (virtually all countries) — you do not need to write "All rights reserved" for copyright to apply, though it is sometimes added for clarity. For business use, the business name is preferred over personal name for branding purposes.
