What this tool does

Every selected image is decoded separately, marked with the same text settings, exported as a new PNG, and added to a ZIP archive.

font size = image width × selected percentage

Text watermarking discourages casual reuse but does not provide cryptographic ownership protection.

Tips for better results

  • Choose a text size relative to the smallest image in the batch.
  • Use moderate opacity so the mark remains visible without hiding the picture.
  • Keep an untouched copy of every original.

FAQ

Does batch watermark images upload my photos?

No. Processing runs in the browser. A pinned library is loaded only when needed, but your selected image bytes are not sent to it or to Callimage.

What happens to image metadata after using this tool?

Canvas-generated image outputs generally omit EXIF and GPS metadata. Keep the original if that information matters.

Why can the result look different from the original?

Decoding, pixel processing, color profiles, and lossy output encoding can change color or fine detail slightly.

Can I use this tool on a phone?

Yes, on a modern mobile browser, although large images may exceed available memory. The tool rejects unusually large inputs before intensive work.

Which files work best with batch watermark images?

Up to 30 PNG, JPEG, or WebP images, 120 MB total. Output is a ZIP containing PNG files.
