Watermark Your Photos in Seconds

Before you share product shots, portfolio work or property photos, a watermark makes it clear who they belong to. QodeCat Watermark puts your name or logo on up to 30 images in one go. Set it up once on a live preview of the first image, then apply it to the whole batch.

  • Text or logo: Type a text and pick its size, color, opacity and rotation, or upload a PNG or SVG logo.
  • Nine positions or tiled: Place the mark in a corner, on an edge or in the center, or repeat it across the whole image.
  • Original quality: Output keeps the pixel size and the format of each file (JPG and WebP at 92% quality).
  • Batch download: Download a single image or all of them as one zip file.

Why use this tool?

Your Photos Stay on Your Device

Most watermark sites upload your pictures to a server first. Here the images are drawn on a canvas inside your browser, so unreleased products, client work and private photos are never sent anywhere.

Scales With Every Image

Sizes are set as a percentage of the image width, so the same settings look the same on a small phone photo and on a large camera file. Mixed batches stay consistent without manual tweaking.

Frequently Asked Questions

Q. Which image formats are supported?

JPG, PNG and WebP. Each result is saved in the same format as its original file. For a logo you can use PNG (ideally with a transparent background) or SVG.

Q. Does the watermark reduce image quality?

The pixel size stays the same. JPG and WebP files are re-encoded at 92% quality, which is visually very close to the original; PNG files stay lossless. Metadata such as EXIF is not copied to the new file.

Q. How many images can I watermark at once?

Up to 30 images per batch. Processing speed depends on your device, since everything runs locally in your browser.
