Add a watermark to photos in bulk

To add a watermark to photos in bulk, you place the same logo or text at the same position on every photo of a series, then export them together. The bulk watermark tool in SwipeAtelier does exactly that, for free and in your browser: choose an image or a text mark, set its position, margin, size and opacity once, preview each photo, and export the whole batch. Your photos are never uploaded.

Why watermark a whole series at once

Photographers, makers and small shops often post several photos from the same shoot. Adding a logo by hand to each one takes time, and the mark ends up in a slightly different place every time. Applying one setting to the whole series keeps the result consistent, and the tool remembers your logo and settings for the next batch.

Logo or text watermark

• Image: your logo as an image file. A PNG with a transparent background is recommended, so only the logo shows.
• Text: your name, handle or website in one of the 8 editor fonts, with color and bold.

Settings

• Position: 9 spots, the four corners, the middle of each edge and the center.
• Margin: the distance between the mark and the edge of the photo.
• Size: relative to the photo, so the mark looks the same on large and small images.
• Opacity: from discreet to fully visible.

Each photo keeps its own proportions: nothing is cropped. The longest side is limited to 4096 pixels. Photos are exported as JPEG, or as PNG when the original is a PNG.

How to add a watermark to photos in bulk

1. Open the bulk watermark tool.
2. Add all the photos of the series.
3. Choose the type of mark: an image (your logo) or a text.
4. Set the position, margin, size and opacity.
5. Go through the preview photo by photo to check that the mark never sits on an important detail.
6. Export. On a computer, the photos come as a ZIP; on mobile, the share sheet saves them to Photos.

Next time, your logo and settings are already there: they are remembered on your device.

Tips for a clean watermark

• A corner position with a small margin is the least intrusive.
• Lower the opacity for a discreet signature; raise it if the photos are often reposted.
• Use a white or light logo on dark photos and a dark one on light photos, or run two batches.
• For Instagram, prepare the right size first with the multi-size resizer, then add the mark. Formats are listed in the Instagram sizes guide.
• Before posting the series, see how the photos sit side by side on your profile with the Instagram grid planner.
