Frequently Asked Questions
How do I compress an image without losing quality?
Use the quality slider to find the optimal balance—typically 80-90% quality provides excellent compression while maintaining visual quality. For photos, JPEG compression at 85% is often indistinguishable from the original. For graphics with text, consider PNG format instead.
What image format is best for web?
WebP is the best format for web, offering 25-35% smaller files than JPEG/PNG with the same quality. For photos, use JPEG or WebP. For graphics with transparency, use PNG or WebP. For animations, use WebP or GIF. Most modern browsers support WebP.
Why should I compress images for my website?
Compressed images load faster, improving user experience and SEO. Google uses page speed as a ranking factor, and faster sites have lower bounce rates. Additionally, smaller images reduce bandwidth costs and mobile data usage for your visitors.
Is it safe to compress images online?
Yes, this tool processes images entirely in your browser (client-side). Your images are never uploaded to any server. They remain on your device at all times, ensuring complete privacy and security.
