Bulk Image Watermark – Add a Text or Logo Watermark to Images in Bulk

Add a text or logo watermark to many images at once. Give the tool a list of image URLs, choose what to stamp and where, and get back every image watermarked, with a ready download link for each one.

A fast, no-code bulk image watermark API: watermark product photos, brand your images, protect photos from theft, or add a copyright mark across a whole batch — in one run, no Photoshop.

Features

• Text or logo watermark — stamp custom text, or overlay a logo image (a transparent PNG works best, so only the logo shows).
• Bulk processing — pass a whole list of image URLs and watermark them in a single run.
• 5 positions — top-left, top-right, center, bottom-left, bottom-right, with a clean inset margin so the mark never touches the edge.
• Adjustable opacity — from a light 10% tint to a solid 100% stamp.
• Readable text — a soft shadow keeps text legible even on busy photos.
• Transparent-edge safe — logo watermarks keep their transparency; no ugly white box.
• Keeps the original format — JPEG stays JPEG, PNG stays PNG, WebP stays WebP.
• Never fails the whole run — if one image link is broken, that row is marked failed with a reason and the rest keep going. Nothing is silently dropped.
• Ready download link per image — every watermarked image comes back with its own URL.

Common use cases

• E-commerce sellers — brand hundreds of product photos with a logo before listing.
• Photographers & studios — protect galleries with a copyright watermark before sharing.
• Marketing teams — stamp campaign images consistently across a batch.
• Content creators — add a channel or brand mark to images at scale.
• Developers — a simple watermark API step inside a larger image pipeline.

How to use

1. Add your image URLs (direct links to .jpg, .png, or .webp files).
2. Pick Watermark type: text or logo.
   • For text: type the words and (optionally) a font size.
   • For logo: paste a logo image URL — ideally a transparent PNG.
3. Choose the position and opacity.
4. Click Start. When it finishes, open the Output tab for a download link per image.

Example input

{
    "imageUrls": [
        "https://example.com/photo1.jpg",
        "https://example.com/photo2.jpg"
    ],
    "watermarkType": "text",
    "text": "© My Brand",
    "fontSize": 48,
    "position": "bottom-right",
    "opacity": 50
}

Output

Each image becomes one row in the results table:

{
    "originalUrl": "https://example.com/photo1.jpg",
    "downloadUrl": "https://api.apify.com/v2/key-value-stores/.../records/watermarked-1.jpg",
    "status": "done"
}

The watermarked images are saved to the run's key-value store. Download them promptly — Apify clears unnamed run storage after its retention period.

Pricing

Pay per image: you are charged only for each image that is successfully watermarked. Failed images (e.g. a broken link) are free. Simple, predictable, no subscription.

FAQ

Does it remove watermarks? No. This tool adds a watermark to your own images. It does not remove watermarks.

What image formats are supported? JPEG, PNG, and WebP. The output keeps the same format as the input.

Do I need a transparent logo? For logo watermarks, a transparent PNG is best — otherwise the logo's background box shows over your photo. Text watermarks need no image at all.

Can it handle a large batch? Yes. Pass a long list of image URLs in one run. For very large libraries, split into multiple runs.

Will one broken link stop everything? No. That image is marked failed with a reason and the run continues with the rest.
