Frequently Asked Questions
How does image compression work?
Our tool uses the browser's Canvas API to recompress images. Adjusting the quality slider changes the JPEG compression level, reducing file size while maintaining visual quality.
What image formats are supported?
We support JPG, PNG, and WebP input formats. Output is always JPG for maximum compatibility.
Is compression really private?
Yes! All compression happens locally in your browser using the Canvas API. Your images are never uploaded to any server.
What quality setting should I use?
For web use, 0.7-0.8 quality provides good balance between size and quality. For photos you want to keep, use 0.85-0.92.
Can I compress multiple images at once?
Yes! You can compress up to 10 images simultaneously with the same quality setting.
