PNG Maker 对比 Palette.fm

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.

Palette.fm 通过浏览器上传流程为黑白照片上色，提供 21 种以上滤镜预设和基于关键词的颜色调整。上传图片，选择滤镜，如有需要调整描述性关键词，然后下载全分辨率结果或继续预览迭代。该照片编辑流程面向家族历史研究者、摄影师和修复旧照片的创作者，无需打开 Photoshop。

大多数上色工具偏重浓重的棕褐色和紫色色调，几乎无法调整肤色或织物颜色。Palette.fm 允许用户点击滤镜后通过简单语言关键词微调色调，并提供一次性积分包和订阅服务。免费预览限制为 500x500 像素并带水印，付费积分则去除水印并支持最高 5000x5000 像素文件。

家谱研究者、照片档案管理员和 YouTube 教育者使用 Palette.fm 批量测试色彩效果后再使用积分。网站报告已上色照片达 5400 万张，注册用户 660 万，提供面向团队的 API 以实现程序化访问。
