Interactive synthetic batch

Place one mark across four example images.

This public demo changes self-created product illustrations only. It uploads nothing and does not claim that a watermark prevents removal.

Three controlled steps

From originals to one consistent marked batch

Add target images.Upload static JPG, PNG, WebP or AVIF files one at a time with validation and retry.
Design the watermark.Use printable text or a PNG/WebP logo, then confirm position, relative size, opacity, margin, rotation and optional tiling.
Review and download.The worker keeps source dimensions, creates safe filenames and returns successful outputs plus a CSV manifest.

Useful for repeated publishing work

Shop previewsApply the same brand mark across a product set before sharing drafts.

Photography proofsPlace an attribution mark over a complete proof batch.

Marketplace assetsCreate consistently positioned marked copies while keeping clean originals separately.

Agency reviewDeliver documented preview files in one organised package.

An honest protection boundary

A visible mark can attribute and discourage casual reuse. It is not copy protection, does not prove ownership by itself and cannot stop deliberate cropping or removal. Keep your unmarked originals independently.

Watermark questions

Bulk Image Watermark FAQ

Clear answers about logos, placement, formats, metadata and deletion.

Can I watermark several images at once?

Yes. One job applies the confirmed text or logo settings to every target image and returns the successful files in a ZIP with a CSV manifest.

Can I use my own logo?

Yes. The protected app accepts a PNG or WebP logo from the same draft. The logo is treated as a watermark source and is not exported as a target image.

Which positions are supported?

Choose any of nine fixed positions, set a relative margin, or use a repeated tiled pattern across the complete image.

Does the tool change image dimensions?

No. Watermarking keeps the source width and height. It composites the watermark without stretching the underlying image.

Which output formats are available?

Keep the original JPG, PNG, WebP or AVIF format, or explicitly convert the batch to one of those formats. JPEG outputs use the confirmed background colour when transparency must be flattened.

Are camera and GPS details kept?

Metadata is removed by default. The protected app shows this setting before the confirmed run.

Does a watermark prevent copying or removal?

No. A watermark can identify and discourage reuse, but it is not DRM and cannot guarantee that a determined person will not remove or crop it.

When are files deleted?

Original images and the logo are deleted after processing. The generated ZIP and previews expire after 24 hours and are removed by the recurring cleanup.
