Usage tips

How to edit and export cleanly

Use Watermark Adder when you need to add text or logo watermarks to images with customizable position, opacity, and size. Batch processing supported.

Most image operations happen locally with Canvas APIs, which keeps the workflow quick and avoids unnecessary uploads for common edits.

Common use cases

  • Prepare a publishable image asset without opening a full design suite.
  • Prepare screenshots, product images, avatars, or social assets for publishing.
  • Resize, convert, annotate, or inspect images during design and content work.

How to use it well

  1. Start in the tool area above and enter the smallest complete input that represents your task.
  2. Adjust size, quality, color, layout, or output options.
  3. Preview the result where available.
  4. Download the processed file and compare it with the original.

Practical tips

  • Keep the original file until you confirm the exported dimensions and quality.
  • Use PNG for sharp graphics and transparency, JPEG/WebP for smaller photographic images.
  • For batch work, test one image first so the same settings can be reused confidently.

Limitations to know

  • Large images can be limited by browser memory and Canvas size limits.
  • Canvas exports may remove some camera metadata such as EXIF information.
