Text or your own logo, stamped across up to 30 images in one run and downloaded as a single ZIP. Nine positions or tiled across the frame. Nothing is uploaded.
Put your name or logo on a whole batch in one go, and have it look right on every size.
Stamp your name, handle or copyright in the editor's fonts, or upload a PNG or WebP logo that keeps its transparency.
The mark is sized as a share of each picture's short edge, so it looks the same on a 4000px photo and an 800px screenshot in the same batch.
Place the mark in any corner, along an edge or in the centre, or repeat it across the whole image so cropping it out stops being practical.
Fade it back to a quiet signature or make it bold, and angle it for a diagonal proof mark. The first image previews every change live.
Mark a whole shoot or catalogue in one pass, instead of opening and exporting every file by hand.
New files are written and the ones you dropped in are never changed, so keep those as your clean masters.
| You are | Setting | Why |
|---|---|---|
| Signing work you are proud of | Corner, 6–10%, 40–60% opacity | Readable, out of the way, not the subject |
| Sending proofs to a client | Tiled, 25% opacity, rotated | Hard to crop out, easy to see through |
| Stock or listing photos | Centre, 20%, low opacity | Covers the part worth stealing |
| A brand logo on product shots | Image watermark, corner, 8% | PNG with transparency keeps the mark clean |
A watermark says who made a picture and puts off casual reuse. It does not lock the picture, and researchers have shown exactly when it is easiest to take off.
When the same mark sits in the same place on many photos, software can learn it and lift it off all of them; researchers at Google showed this on real stock-photo watermarks. A batch here puts the same mark in the same place on every file, so treat it as a signature, not a lock. Tiling it across the picture makes removal harder, not impossible.
“We show that this consistency allows to automatically estimate the watermark and recover the original images with high accuracy.”Four jobs where a name, a notice or a purpose line belongs on the image, and two where it must stay off the copy you upload. Every rule links to its official source.
The US Copyright Office describes a notice as the © symbol, a year and the owner's name, and says owners of unpublished work may want notices on copies that leave their control. A gallery of client proofs is exactly that.
How it helps
Type © 2026 and your name, tick Repeat across the whole image, then add some Rotation at about 25% opacity. A whole shoot of up to 30 images runs in one pass, and your clean masters are never changed.
The UK Intellectual Property Office notes that uploading and downloading images can strip the hidden file details that name the copyright owner. A credit that lives only in those details can be gone after the image has moved around once.
How it helps
Put the credit in the pixels: your handle as text, or a transparent PNG logo, in a corner at 6–10% size. Stripping file details can't remove it. The new files don't carry those details either, so keep your originals.
The Dutch government advises never simply handing over an ID copy, even for a rental contract. On a secure copy you write that it is a copy, which authority or product it is for, and the date, and make your BSN unreadable.
How it helps
Type something like "Copy for [agency], 15 Sep 2026", tick Repeat across the whole image and angle it so it cannot be cropped off. Hide the BSN with Blur Image first. The ID never leaves your device.
Fiverr can watermark image files in a delivery message until the client accepts the final delivery, but that watermark is not added to files sent through the inbox or order messages. A mockup shared in a quick message goes out clean.
How it helps
Before attaching concepts to a message, run them through with your name tiled at low opacity. The client can still judge the layout, cropping the mark out stops being practical, and one setting fits a batch of mixed sizes.
Adobe Stock lists uploading content with watermarks, branding or logos among the common reasons submissions are refused. The same photos often go on your own site and social feed too, where anyone can save them.
How it helps
Watermark a copy for your portfolio and social posts, and submit the untouched originals to Adobe Stock. The tool writes new files ending in -watermarked and never alters the ones you dropped in.
eBay's picture policy does not allow watermarks of any type, including those used for ownership attributions, or photos with added text or borders, and eBay may remove listings that break it. Many sellers post the same photos elsewhere as well.
How it helps
Keep one clean set for eBay and stamp a second set for Instagram or Facebook posts. Up to 30 photos go through in one run and download as a single ZIP, and the originals stay exactly as they were.
Yes — up to 30 in one go, downloaded as a single ZIP. Batch is the one thing a full editor cannot do quickly, and it is what this page exists for.
Yes. The size is a percentage of each image's short edge rather than a pixel value, so a 4000px photo and an 800px screenshot in the same batch come back with a stamp that reads the same size.
Yes — a PNG or WebP with transparency. A JPG logo can't be see-through and will show up as a solid rectangle, which is why the picker only takes the two formats that keep it.
It is drawn into the pixels, so there is no layer to switch off. That is not the same as unremovable — anyone determined can paint over a corner mark, which is why the tiled option exists for images you want harder to reuse.
No. The stamp is drawn by your own browser and the ZIP is built there too.
