1Upload the JPEG 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 JPEG file; nothing else is added to it.
Watermark JPEG FAQ
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.
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 the file format affect how the watermark comes out?
+
It does. JPEG is the same codec as JPG under a longer extension — identical DCT pipeline, identical quantisation tables, nothing about the pixels changes with the filename. That governs how cleanly a semi-transparent mark can be blended into the underlying content.
Anything specific to JPEG worth knowing?
+
Yes — the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes. It affects when in your workflow the mark should be applied.
Can I run Watermark JPEG on several JPEG images at once?
+
Yes. Drop the whole set into the upload area and they queue in parallel with identical settings — that is the main reason to do this in a browser rather than one file at a time in an editor. Free accounts run one file per batch; a pass lifts that.
What happens to EXIF and colour profile data?
+
It depends on the tool. Compression strips EXIF and the embedded colour profile to save space, while edits such as resizing or rotating can keep them. There is no setting on this page to choose, so check the file with a metadata viewer before publishing it if location data matters.
Does Watermark JPEG cost anything?
+
No. Watermark JPEG is free without an account and adds no watermark. The upload and the result are deleted automatically about 24 hours after the job, which leaves time to download the result.
Why does a WebM site host Watermark JPEG?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Watermark JPEG on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once Watermark JPEG is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is Watermark JPEG here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
