Batch Watermark Images
Apply one text or logo watermark to as many as 20 images without uploading the source files. Control placement, opacity, scale, text color, and padding, preview the result in the batch queue, and download verified image files in a ZIP archive.

Built for dependable batch work
This tool creates a visible ownership or review mark on flattened copies. It does not provide forensic watermarking, rights management, tamper detection, or guaranteed protection against cropping and editing. Keep unwatermarked masters and treat the exported ZIP as a delivery copy.
One consistent mark across many files
Built for repeatable image workflows with clear output evidence.
Nine practical placement positions
Your selected files remain in the current browser session.
Local preview and rendering
Each queue row reports its own result without blocking valid files.
Source masters remain unchanged
Downloadable output uses names and formats that match the generated bytes.
How to use Batch Watermark Images
A four-step workflow keeps the original files separate from generated output.
- 1
Add files
Add source images and choose text or logo mode.
- 2
Kies instellingen
Set the mark, position, opacity, scale, and padding.
- 3
Process locally
Process the queue and inspect representative previews.
- 4
Verify and download
Download the verified watermarked copies as a ZIP.
What this batch tool does
This tool creates a visible ownership or review mark on flattened copies. It does not provide forensic watermarking, rights management, tamper detection, or guaranteed protection against cropping and editing. Keep unwatermarked masters and treat the exported ZIP as a delivery copy. Every item is handled independently, so one unsupported or damaged file does not erase successful work from the rest of the queue.

Batch Watermark Images guide
Use these checks to get output that fits the destination rather than stopping at a successful download.
Choose text for speed and logo for identity
A text watermark is useful for review labels, photographer names, domains, dates, or status language such as PROOF. The browser scales the font relative to each image so a mixed-size batch remains readable. A logo gives stronger visual identity and supports transparency, but its source artwork should already have clean edges and enough contrast. The logo is decoded locally and never uploaded.
Balance position, padding, and opacity
Corner placement keeps the main subject clearer, while centered marks are harder to remove with a simple crop. Padding is measured as a percentage of the shorter image edge so spacing behaves consistently across portrait and landscape files. Lower opacity reduces distraction but can disappear over complex areas. Always inspect both a light and dark source because one setting rarely has identical contrast everywhere.
Understand scale across a mixed batch
The scale control describes the mark relative to each image rather than assigning one fixed pixel width. That approach prevents a logo prepared for a large photo from overwhelming a small graphic. Text uses responsive font sizing, while a logo preserves its original aspect ratio. Extremely narrow or unusually tall images may still need a separate pass because any universal placement is a compromise.
Export delivery copies, not masters
The generated files are flattened and newly encoded. Metadata, editable layers, vectors, and animation are not preserved. JPEG quality can affect small text edges, so zoom into representative results. Keep the original files outside this workflow, name the marked versions clearly, and verify the ZIP before distribution. A visible watermark communicates ownership or review status; it is not a replacement for contracts, licensing records, or access control.
Batch quality checklist
Start with copies when the source collection is valuable, and keep filenames that let you trace every result back to its original. Test a small representative set before processing the full queue, including the largest file, a transparent image, a portrait, and a landscape image. After processing, compare pixel dimensions, format, file size, transparency, text sharpness, edge detail, and color in the actual destination. A successful browser status confirms that this tool completed and verified its expected output structure; it does not replace editorial review or the receiving platform’s rules. Keep the downloaded ZIP or CSV with the settings used for the run, then record exceptions that need individual treatment. For publishing workflows, also check descriptive alternative text, rights, consent, naming conventions, backup policy, and cache behavior. These steps make a repeatable batch safer than treating every completed download as automatically ready for production.
Veelgestelde vragen
Practical answers about formats, privacy, quality, and browser behavior.
Can I use a logo instead of text?
Yes. Choose logo mode and load a browser-decodable image with transparency if needed.
Does one setting work across different image sizes?
The watermark scales and pads relative to each image, which keeps mixed batches more consistent than fixed pixels.
Can a watermark prevent image theft?
No visible mark is impossible to remove. It is a deterrent and ownership signal, not complete technical protection.
Will my original files be changed?
No. The tool creates new browser-generated copies and leaves selected source files untouched.
Can PNG transparency be retained?
Yes for the source and logo when PNG output is used. JPEG output is flattened to an opaque background.
Are files sent to a server?
No. Source decoding, logo rendering, text drawing, encoding, and ZIP packaging remain local.
Why should I inspect more than one result?
Watermark contrast and subject overlap vary by composition, even when size and placement are mathematically consistent.
