1Upload the images you want to mark, already at their final size — watermarking comes after resizing, not before it.
2Upload a transparent PNG logo or type your text, then choose the font, the colour and the opacity.
3Set the position, or switch to a tiled repeat when a single corner mark would be too easy to crop away.
4Download the watermarked Image file; nothing else is added to it.
Watermark Image FAQ
Does the file format affect how the watermark comes out?
+
It does. this format is read and written by the same streaming pipeline as everything else we support. That governs how cleanly a semi-transparent mark can be blended into the underlying content.
Anything specific to Image worth knowing?
+
Yes — the pipeline reads the real format from the file header rather than the extension, so a mislabelled upload still works. It affects when in your workflow the mark should be applied.
Does a watermark actually protect my work?
+
It deters casual reuse and it credits you; it is not security. A corner mark can be cropped and a faint one can be painted out. If protection matters, a large semi-transparent mark across the subject is far harder to remove than a discreet one in a corner.
How does Watermark Image place the mark?
+
Concretely, the mark is composited per file with position, scale and opacity applied consistently, which is how you brand a whole set of images identically in one pass. You control the position, the size and the opacity, and the same settings are applied consistently across everything you upload.
Can I run Watermark Image on several images at once?
+
Yes, and mixing formats in the batch is fine — settings are applied per file with the right decoder for each. Free accounts run one file at a time; a pass removes that.
What happens to metadata and transparency?
+
EXIF and the ICC colour profile are carried across wherever the target format supports them, and an alpha channel survives into any format that has one. Transparency is only flattened when the destination format has no way to represent it.
Is there a file size limit on Watermark Image?
+
Yes: free accounts process images up to 5 MB each regardless of which image format you brought; ImageMagick, libjpeg-turbo, libpng and libwebp do the actual work. The cap is per file, so a batch of twenty 5 MB photos is fine even though the total is well over the limit.
Will Watermark Image lower the quality of my images?
+
That depends on what you brought. A lossless source (PNG, BMP, TIFF) round-trips exactly; a lossy one (JPG, WebP, GIF) is already the product of one quantisation pass and only re-encodes if the operation genuinely requires it.
Why does a Word site host Watermark Image?
+
WORD.to is built around the editable end of a document's life — the DOCX that is still being written, still being styled and still being argued over, before anyone flattens it for sending. Office files are containers full of other people's media — images, embedded audio, fonts — so the work people need on them is usually the work they would need on those contents anyway. Watermark Image shares the upload, the caps and the account with the conversions for that reason.
What should I do with the result once Watermark Image is finished?
+
The converter on this site takes documents out to PDF for sending, to images for embedding and to plain text for anything that has to read them programmatically, and back the other way. Doing that afterwards keeps the editable original around, which is the part you cannot get back once it has been flattened.
Is Watermark Image here the same tool the sibling sites run?
+
The engines are shared — the same document toolchain, the same workers, the same limits. What a Word site adds is a view on what survives leaving the Office format and what does not, which is the question every one of these jobs actually turns on. It also starts from one fact about the format this site is named after: the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
