❓ FAQ
For web use, 70-85% provides a good balance between file size and visual quality. Use 90-95% for print or archival purposes. PNG is lossless so the quality slider does not apply to it.
WebP provides 25-35% smaller file sizes than JPG at comparable quality. All modern browsers support it, making it the recommended choice for web use. Choose JPG for maximum compatibility with older software.
No. All compression is done entirely in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy.
JPG doesn't support transparency. Transparent areas will be filled with a white background. To preserve transparency, choose PNG or WebP as the output format.
