Are my photos uploaded?

No. Each photo is decoded, watermarked and saved again inside your browser. Nothing is sent to CAPTD or anyone else.

Does watermarking reduce quality?

PNGs stay lossless. Other formats are saved as a JPEG at 92% quality — visually very close, but re-encoded. Keep your originals and watermark copies.

Does it keep the EXIF data?

No. The new file is built from the pixels, so camera settings, dates and location are not carried across — the same as the Metadata Stripper.

How many photos can I watermark at once?

Up to 50 per batch. For more, run it again — your settings stay while the page is open.

Why does the watermark look the same size on every photo?

Its width is set as a share of each photo's width, so a 25% mark is a quarter of the width on a phone shot and on a 45-megapixel file alike.

Batch Photo Watermark

Put your name or logo on up to 50 photos at once — in a corner, in the centre, or tiled across the frame — and download them together as a ZIP. Every photo is processed in your browser; none is uploaded.

PNG photos stay PNG; everything else is saved as a JPEG at 92% quality. Like the metadata stripper, the copies carry no EXIF or location data. Keep your originals.

How to use this

What it does

Draws a text or logo watermark onto each photo you add — up to 50 at a time — at the same relative size and position, so it looks the same on portrait and landscape shots. The watermark's width is a share of each photo's width; tiled marks repeat diagonally across the whole frame.

What you'll need

The photos to watermark (JPEG, PNG, WebP, and HEIC where the browser can open it).
Your watermark text, or a logo file.
Where it goes, how big and how see-through.

Steps

Add your photos — drop them on the box or choose them.
Type your watermark, or switch to Logo and choose your logo file.
Pick a position (or Tiled), then set the size, opacity and margin while you watch the preview.
Download: one photo saves directly, several come as a ZIP.

Reading the result

The preview shows the photo you've selected in the list, scaled down. The downloaded files are full size with the watermark drawn at the same proportions.

Tips

For proofs you don't want screenshotted, use Tiled at 30–40% opacity — a corner mark can simply be cropped off.
For portfolio images, a small corner mark at 40–60% opacity credits you without spoiling the photo.
A logo saved as PNG with a transparent background looks far cleaner than one on a white box.

Should photographers watermark their photos?

A watermark is a visible name or logo on a photo. It credits you when an image is shared without context, and on client proofs it discourages people from using the images before they're paid for.

It's a deterrent, not protection: a determined person can crop or retouch a mark out. Your copyright exists whether or not the photo is watermarked.

Why photographers use it

Images travel far from where they were posted. A tasteful mark means a repost still carries your name, and a proof gallery with tiled marks keeps clients ordering the clean files instead of screenshotting.

Common mistakes

A watermark bigger than the subject. it distracts from the work you're trying to show; keep portfolio marks small.
Watermarking the only copy. the watermark is drawn into the pixels; keep your originals.
Expecting a corner mark to protect proofs. it crops off in seconds. Use Tiled for proofs.
