Does this upload my photos to a server?

No. Watermarking runs entirely in your browser using the Canvas API. Up to 30 photos are decoded locally, processed with your watermark spec, and bundled into a ZIP - all without a single network request.

What's the maximum number of photos I can watermark at once?

30 photos per batch. Above that, browser memory becomes unreliable on phones (especially older iPhones with HEIC sources). For more, run multiple batches sequentially.

How does bulk save work?

Click 'Save all (.zip)' - we process each photo sequentially with a progress bar, then bundle every result into a single ZIP file named watermarked-photos- .zip. One click, one download.

Does each photo get the watermark in the same spot?

Yes - position is stored as percent of the photo's dimensions, so a single Anchor lands consistently on photos of mixed aspect ratios. If you drag the watermark in the preview, the custom percent applies to every photo too.

Can I use my own logo as a watermark?

Yes - switch to Logo mode and upload any image (PNG with transparency works best). Adjust size as a percent of the photo and tune opacity to taste. The same logo applies to the whole batch.

Does the output have any 'made with...' watermark?

No. The output is pixel-clean - exactly what you'd get if you'd watermarked the photos in Photoshop yourself. We never overlay our brand on your work.

Why use this online tool

Up to 30 photos at once

Bulk apply the same watermark to a whole batch - portfolio, product catalogue, event coverage. Each photo processed locally with progress tracking.

Live drag-to-place

Drag the watermark anywhere on the preview. Same percent-based position applies to every photo in the batch, regardless of dimensions.

Settings remembered

Your text watermark spec persists between sessions - drop a new batch and your © Studio 2026 styling is already there.

100% browser-side, free

Photos never leave your device. No upload, no watermark on output (the irony), no signup, no per-photo cost.
