Add Watermark to Image Online Free. Protect Certificates, Photos, and Documents - Text or Logo.

RepetiGo's free image watermark tool lets you add a visible text or logo watermark to any photo, certificate, document scan, or graphic. Type your name, institution, or custom text, or upload your logo - drag it into position, set its opacity and rotation, and download the protected image. No software required, no account needed, and your image is never uploaded to a server.

Adding a watermark to an image embeds a visible mark - your name, studio logo, "DRAFT," "CONFIDENTIAL," or any custom text - directly into the image file. Once embedded, it becomes a permanent part of the downloaded image, helping deter unauthorized copying, misuse, or falsification.

A watermark serves as both a visible identification mark and a deterrent against unauthorized use. Different users add watermarks for different reasons - here are the most common:

Click Add Text or Add Image to place a watermark layer on your photo - you can add as many text and logo layers as you like and combine them:

Text layer - type your name, studio name, website, or a notice like "DRAFT," "CONFIDENTIAL," or "PROOF." Choose font, size, bold/italic/underline, colour, opacity, and rotation - drag it anywhere on the image, diagonal placements are harder to crop out.

Logo layer - upload your logo (a PNG with a transparent background gives the cleanest result). Drag it into position and adjust its size, opacity, and rotation independently from any text layers.

India tip: for certificates and official documents, add your institution name as a diagonal text layer at 30-40% opacity, dragged across the centre. Visible enough to deter falsification without obscuring the document.

Click Watermark Image (or Download Watermarked Image). The watermark is permanently drawn into the image on your device, and downloads as PNG or JPG - whichever you choose. If you want the same watermark on more photos, scroll down to Apply This Watermark to More Images, upload the rest, click Apply, and download them individually or all together as a ZIP.

A logo layer uses an image - your logo, signature, or custom graphic - as the watermark element. For the cleanest result, use a PNG logo with a transparent background rather than a JPG with a white box around it. If you only have a JPG logo on a white background, run it through Remove Background at Open Remove Background first to get a transparent PNG, then upload that as your watermark logo. You can add a logo and one or more text layers on the same image at once.

There are no fixed position presets - you drag each watermark layer directly on the image to wherever you want it, and each layer's opacity and rotation are independent sliders.

These are the watermarking needs specific to India - certificate protection, print shop proofing, and professional photography - that drive the most practical value:

Print shops share design proofs, ID card prints, photo proofs, and certificate designs with customers before final payment. Without a watermark on the proof, some customers print directly from the proof and don't pay for the final file. A clear "PROOF ONLY - NOT FOR PRINT" watermark is standard practice to prevent this.

PrintPilot - RepetiGo's print shop software - can fold proof watermarking into the same automated workflow customers already use to upload documents via QR code, instead of a shop owner watermarking every proof by hand.

Upload your certificate scan. Click Add Text and type your institution name or a notice like "XYZ College - Not for Reproduction." Set the rotation slider to around 45° for a diagonal look, and opacity to 30-40% - clearly visible without obscuring the certificate content. Drag it across the centre of the image. Download. The diagonal watermark makes it noticeably harder to edit the certificate content without disturbing it. For stronger protection, add a second or third copy of the same text layer and drag each to a different part of the image.

Upload your photo. Click Add Image and upload your studio logo (a PNG with a transparent background gives the cleanest result), or click Add Text and type your name or studio. For a finished photo being delivered to a client, drag the watermark to a bottom corner and set opacity around 20-30% - subtle but present. For a proof not yet paid for, drag it across the centre, rotate it diagonally, and set opacity to 50-60% - clearly visible. Download. The watermark is permanently drawn into the downloaded image.

It depends on the purpose. For subtle branding on delivered photos: 15-25% - barely visible but present. For certificate protection and professional proofing: 30-50% - clearly visible but the image content still readable through it. For strong proof/draft protection: 60-80% - prominently visible, partially obscures the image. For a maximum copyright lock: close to 100% - the watermark itself becomes fully solid. The most common setting for Indian professional use (certificates, proofs, photo sharing) is 30-50%.

Use RepetiGo's browser-based watermark tool at Open Watermark Image - no Photoshop, no software installation, no subscription. Upload your image, add your text or logo, drag it into place, set opacity, download. If you have a set of photos that all need the same watermark - an entire wedding album, for example - design the watermark once on your first photo, then upload the rest under "Apply This Watermark to More Images" to stamp all of them the same way in one pass.

In Canva: create a design, upload your image, add a Text element with your watermark text or upload your logo as an element, adjust the element's opacity in its settings, and position it over the image before downloading as JPG or PNG. Canva's free tier limits some export options. For watermarking a standalone image file without building a design from scratch, RepetiGo's dedicated tool is more direct - upload the image, add your watermark, download.

Word has a built-in watermark feature, but it applies to Word documents, not standalone image files: go to the Design tab, click Watermark, and choose a preset ("DRAFT," "CONFIDENTIAL," "DO NOT COPY") or Custom Watermark for your own text or picture watermark, then Apply. This watermarks the document background, not a JPG or PNG file. To watermark a standalone image file, use RepetiGo's watermark tool at Open Watermark Image instead.

Yes. Design your watermark - text, logo, or both - on your first uploaded image exactly the way you want it. Then, in the "Apply This Watermark to More Images" section below the main editor, upload the rest of your photos and click Apply. The same layers, positions, and opacity are stamped onto every image you added, and you can download each one individually or all together as a ZIP archive. This is useful for wedding photographers watermarking a full event gallery, print shops adding "PROOF" marks to several designs, or businesses marking a batch of product photos.

No. RepetiGo's watermark tool does not add any tool branding, logo, or watermark to your output image. The only watermark in your downloaded image is the one you created - your text, your logo, your settings.

No. RepetiGo's watermark tool is for adding watermarks to images you own - not for removing watermarks from images.
