常见问题
能拼几张图？
数量不限，一次添加多张即可。图越多长图越长，建议控制尺寸避免过大。
长图会太大吗？
拼图尺寸是所有图尺寸之和，可能很大。可先用图片压缩工具瘦身再拼，或减少张数。
图片上传吗？
不上传。拼接在你浏览器内存里完成，结果直接下载，刷新即清空。
English
Trip guides and reviews often work best as a single long image — multiple shots merged into one horizontal or vertical strip. This tool stitches them in the order you add, with adjustable gap and background.
Everything runs in your browser; nothing is uploaded. Horizontal centers on the tallest image, vertical centers on the widest.
FAQ
How many images can I stitch?
Unlimited — add several at once. More images make a longer strip, so keep total dimensions reasonable.
Will the result be too large?
The strip is the sum of all image sizes and can get big. Compress images first or use fewer shots.
Are images uploaded?
No. Stitching happens in browser memory, the result downloads directly, and a refresh clears everything.
