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
Can I use my own logo, or only text?
+
Either. Upload a transparent PNG logo, or type text and choose the font, colour and opacity. A tiled repeat is available when one corner mark is too easy to crop away.
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.
Should I watermark before or after resizing?
+
After. Watermark the final deliverable at its final size, so the mark stays legible and proportionate. Watermarking a master you will process again means the mark gets resampled and compressed along with everything else.
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.
Does Watermark Image cost anything?
+
No. Watermark Image is free without an account and adds no watermark. Uploads are deleted from the workers shortly after the job completes.
Which image formats does Watermark Image accept?
+
All of the common ones — JPG, JPEG, PNG, WebP, GIF, BMP, TIFF, SVG, ICO, PSD, JFIF and HEIC. You can mix formats freely in one batch; each file is identified from its header and routed to the right decoder.
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.
Does Watermark Image belong on a site about a photo format?
+
JPEG.to is built around the format that carries nearly every photograph in existence — thirty years old, opened by literally everything, and still the right default for a photographic image. The jobs people bring here are the ones a photograph collects over its life — too big to email, wrong dimensions for a form, wrong way up out of a phone. Watermark Image runs on the same upload and the same account as the conversions because that is where those jobs land.
What is the sensible next step after Watermark Image?
+
The converter on this site moves images to and from JPEG, PNG, WebP and HEIC, which is where the trade between file size and one more generation of loss gets settled. Deciding the format last rather than first is the whole point: every extra save of a photographic image is another generation, and the fewer of them you spend, the more of the picture survives.
Is this the same engine as the other converter sites?
+
Yes — the same libraries, the same workers, the same caps. The difference is which advice is on the page, and here that advice is built on one property of the format the site is named after: the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes.
Is anything kept, and do I need to sign in?
+
Nothing is kept and no account is needed. Uploads are removed from the workers shortly after the job finishes; nothing is looked at, listed or indexed. An account buys history and larger batches, not access.
