隐私和清理说明

This tool runs in your browser with local JavaScript. Your files or pasted lines do not need to leave your device for the main operation.

Use the visible Reset, 清除, Remove, or Delete local result controls when you finish. Large files can still be limited by device memory, browser canvas limits, or mobile performance, so test sensitive work with non-confidential samples first.

How to use this tool

  • Upload two or more images and check the file list before merging.
  • Choose vertical for long screenshots, horizontal for before/after comparisons, or grid for product/social previews.
  • Preview first so you can catch wrong order, excessive gaps, or background issues before downloading.
  • Export as PNG for crisp graphics or JPEG for smaller photo-heavy files.

Who this helps

Useful for SEO editors making comparison images, ecommerce operators assembling product views, bloggers building tutorial screenshots, and creators preparing quick social layouts.

常问问题

Are my images uploaded?

不. The merge preview uses browser canvas, so the main merge operation happens on your device.

Why can very large images fail?

Browsers have canvas size and memory limits. If a huge file fails, resize or compress it first.

Can I change image order?

For this lightweight version, upload images in the order you want. A drag-reorder version is planned for a later quality pass.
