Overview

Batch Image Watermark allows you to quickly protect your visual content by applying custom text or image watermarks to up to 100 images simultaneously, with full control over positioning, opacity, and styling.

When to use

  • Protecting your photography or digital artwork from unauthorized use before sharing online.
  • Adding consistent branding or company logos to a large collection of product images.
  • Standardizing copyright information across a batch of images for professional distribution.

How it works

  1. 1Upload your images and select either a text or image-based watermark.
  2. 2Adjust the position, opacity, font settings, or scale to fit your specific requirements.
  3. 3Configure output settings such as format and quality, then process the files in bulk.

Use cases

  • Photographers adding copyright signatures to event photo galleries.
  • E-commerce sellers applying brand logos to product catalogs.
  • Content creators marking social media assets with custom handles.

Compare alternatives

  • Convert files into Data URIs (Base64 or percent-encoded) for inlining images, fonts, and assets directly into HTML, CSS, or Markdown

  • Convert images to exact monochrome, indexed, grayscale, RGB, or RGBA PNG bit depths with verified output.

  • Convert multiple images to different formats with quality settings and batch processing

Who it's for

Best for

  • Convert images in the browser.
  • Workflows where Watermark Type matters, such as Text Watermark or Image Watermark.
  • Repeatable jobs with images and the same settings every time.

Not ideal for

  • Fully automated batch jobs — this page is built for interactive use; use the API endpoint for scripts.
  • Files in formats this tool does not accept — it works with .jpg, .png, .webp, .bmp input.

Edge cases & common failures

  • Very large files

    Large files take longer and can hit browser memory limits — try a smaller sample first.

  • Skipping the output check

    Compare the first rows or pages of the output with the input before using it in production.

  • Files from unusual exporters

    Some files use format variants that do not convert cleanly — if the output looks wrong, re-save the file from the app that created it and try again.

Examples

1. Protecting Event Photography

Professional Photographer

Background

Problem

How to use

Upload all 50 images, select 'Text Watermark', and set the position to 'Bottom Right'.

watermarkType: text, watermarkText: © 2024 PhotoStudio, position: bottom-right, opacity: 60
