图像工具 — About These Tools
Image utilities resize, crop, compress, and convert pictures entirely on your device using canvas and WebCodecs. Because files are never uploaded, these tools are safe for private or client-confidential images.
常见问题
Are my images uploaded to a server?
No. Every image tool processes files locally in your browser using canvas APIs. Nothing is uploaded, which makes them safe for private photos and confidential assets.
What formats can I convert between?
JPG, PNG, WebP, GIF, BMP, and AVIF depending on the tool and your browser’s encoder support. The output format is shown next to each download button.
Will compression reduce image quality?
Lossy formats (JPG, WebP) trade a little quality for size — you control the quality slider. PNG compression is lossless: pixels stay identical, only the file shrinks.
