What image formats can I compress?

You can compress JPEG, PNG, WebP, GIF, and BMP images. The tool supports output in JPEG, PNG, and WebP formats.

What quality setting should I use?

For web images, 70-80% quality offers a good balance. For archival, use 90-95%. For thumbnails or previews, 50-60% is often sufficient.

Is my image data secure?

Yes! All compression happens locally in your browser. Your images are never uploaded to any server.

Why is my PNG larger after compression?

PNG is a lossless format. For better compression, convert to JPEG or WebP which use lossy compression.

WebP is a modern image format developed by Google that provides superior compression for both lossy and lossless images, typically 25-35% smaller than JPEG.

Will compression affect image quality?

Yes, lossy compression (JPEG, WebP) reduces quality to achieve smaller file sizes. Higher quality settings preserve more detail but result in larger files.

What is the maximum file size I can compress?

The tool supports images up to 50MB. Larger files may cause browser performance issues.

Can I compress multiple images at once?

Currently, the tool processes one image at a time. For batch processing, consider the premium version.

Why does JPEG not support transparency?

JPEG format does not support alpha channels (transparency). Use PNG or WebP if you need to preserve transparency.

How do I choose between JPEG, PNG, and WebP?

Use JPEG for photos, PNG for graphics with transparency or sharp edges, and WebP for best compression with modern browser support.
