JPG 转 PNG
在浏览器内把 JPG/JPEG 图片转换为 PNG。
关于这个工具
JPG is compact for photos, but PNG is often easier for design tools, UI assets, and lossless editing. PixWarp decodes the JPG in your browser and exports a PNG without sending the file away.
使用步骤
- 01
Drop one or more JPG or JPEG images.
- 02
PixWarp decodes each image locally.
- 03
Preview the generated PNG output.
- 04
Download each PNG file.
隐私说明
只要工具可以在浏览器内完成处理，源文件就不会上传到 PixWarp 服务器。处理过程在你的设备本地进行。
输出说明
- • PNG output is lossless, so it may be larger than the original JPG.
- • The conversion does not recreate transparency because JPG does not contain alpha data.
- • Runs locally with browser Canvas APIs.

常见问题
- Why is the PNG bigger than the JPG?
- PNG keeps pixels lossless. JPG is a lossy photo format designed for smaller files.
- Does this add transparency?
- No. JPG files do not include transparency, so the PNG keeps the visible pixels from the source image.
