PNG Maker 对比 AI Image Enlarger

PNG Maker is an online tool that turns text prompts into PNG images with transparent backgrounds. It targets designers, marketers, and content creators who need clip-art style assets, logos, or graphics without opening desktop editing software.

You type a description of what you want, pick an aspect ratio, and the app generates one or more PNG files you can download. The web app also supports image-to-image generation, so you can upload a reference and refine the output from there. Free users get 9 credits per day; paid plans unlock higher monthly credit limits, batch generation, and private outputs.

The site also organizes outputs by tags and runs a blog with tips for writing better prompts. If you need quick transparent PNGs for slides, social posts, or web layouts, it keeps the workflow in the browser with no install required.

ImgLarger 运行一套基于浏览器的图像编辑工具，核心功能是无需桌面软件即可对照片进行放大、超分辨率提升、锐化和扩展。上传 JPG、PNG 或 WebP 文件，选择 AI Image Enlarger 或 AI Image Extender 等专用工作流，预览处理前后的对比效果，然后下载结果。

基础照片编辑器会拉伸像素并留下块状伪影；ImgLarger 使用基于 SRCNN 的模型以 2 倍、4 倍或 8 倍的比例重建边缘和纹理。免费版将输入限制在 1024px 和 2 倍放大，而高级版解锁了 8 倍输出和批量处理功能，价格为每月 9.99 美元并包含 2,000 点积分。像 Let's Enhance 或 Topaz Gigapixel 这样的竞争对手主要面向拥有桌面应用的专业人士；ImgLarger 则将所有功能保留在浏览器中，并捆绑了免费的转换器和裁剪工具。

摄影师、电商卖家和动漫粉丝将其用于产品拍摄、老照片修复、背景去除和生成式扩展。上传的文件会在六小时内自动删除，除了桌面端外，还支持 iPhone 和 Android 的移动端浏览器。
