Why watermark your images here

Built for the way people actually protect a set of photos, not just one.

Your photos and your logo stay on your device
The watermark is drawn on a canvas in your own browser. No upload, no server copy, nothing to delete afterwards.
Watermark a hundred images in one pass
Set it once and every image in the batch gets the same treatment, then download the lot as a single ZIP.
Sized relative to each image, not in fixed pixels
Size and position are stored as a percentage, so a 4000px photo and an 800px thumbnail come back looking consistent instead of one being unreadable.
Tiled and rotated, not just parked in a corner
Repeat the watermark diagonally across the frame so it cannot simply be cropped away or painted over.
Text and logo at the same time
Most tools make you choose one. Here both layers render together, each with its own size, angle and opacity.
Blur out what should not be published
Draw a box over a face, a number plate or an address and pixelate or blur it in the same pass as the watermark.

Watermark questions, answered

Are my photos uploaded anywhere?
No. The page loads your files with the browser's own file reader and draws everything onto a canvas on your machine. There is no upload request, which also means your logo file never leaves your device either.
Can I watermark several images at once?
Yes, up to 100 in one pass. The text and logo settings apply to the whole batch, and the download comes back as a single ZIP with every file inside.
Why is the watermark size given as a percentage instead of pixels?
Because a batch is rarely all one size. A 40px caption is bold on a 600px thumbnail and almost invisible on a 6000px photo. Sizing by percentage of the image width means every file in the batch comes back with the watermark taking up the same share of the frame.
Does the watermark damage the original file?
Your original file is untouched — the browser only reads it. What you download is a newly encoded copy with the watermark drawn in. Keep the original if you may need a clean version later.
Is a tiled watermark really harder to remove?
It is harder, though nothing is impossible. A single corner mark can be cropped off in seconds. A rotated pattern repeated across the frame overlaps the subject itself, so removing it means reconstructing parts of the picture rather than trimming an edge.
What is the difference between pixelate and blur?
Pixelate replaces the area with large flat blocks, so the original detail is genuinely thrown away. Blur smears neighbouring pixels together; at a low strength some detail can survive, so use a high strength — or pixelate — for anything that actually matters.
How do I add my logo to a photo?
Switch to the Logo mode and pick your logo file — a PNG with a transparent background works best. Set its size as a percentage of the photo so it stays proportional across a mixed batch, then choose a position, opacity and angle. The logo is read by your browser and is never uploaded either.
How do I blur out a face or a licence plate?
Switch to the Blur area mode and drag a rectangle over the part you want hidden. You can pick blur or pixelate and set how strong it is. Areas are stored per image, so in a batch each photo keeps its own.

What people use this for

A watermark is not only a signature. The same overlay engine covers four fairly different jobs, and the settings you want differ for each.

  • Claiming your own work — a name or handle in a corner at low opacity, or tiled across the frame when the image is likely to be reposted. Photographers, illustrators and anyone sharing proofs with a client.
  • Branding product shots — drop in a logo file instead of text, put it in a consistent corner and keep it the same size relative to each photo, so a batch of listings looks like a set rather than a pile.
  • Overlaying one image on another — the logo layer takes any PNG, so it doubles as a way to place a badge, a sticker or a second photo on top of the first, at whatever size, angle and opacity you set.
  • Hiding what should not be published — draw over a face, a licence plate, an address label or an account number and blur or pixelate it. Each area belongs to one image, so a batch can be redacted in different places.

A corner mark or a tiled one?

A corner mark keeps the picture readable and is enough when you only want attribution — but it is also the easiest thing in the world to crop off. A tiled, rotated, semi-transparent mark cannot be cropped away without destroying the image, which is what you want for proofs and previews. Diagonal tiling is harder to remove than a straight grid, because a repeating pattern aligned to the pixel grid is much easier for software to average out.
