Understanding Image Compression

Lossy vs Lossless: JPEG uses lossy compression (smaller files), PNG uses lossless (perfect quality)

Quality Setting: 80-85% provides excellent balance of size and visual quality

WebP Format: Modern format offering 25-30% better compression than JPEG

Dimension Reduction: Resizing images has the biggest impact on file size

Tips & Strategies

Web Optimization: Use 80-85% quality for web images, 1920px max width

Social Media: Instagram 1080px, Facebook 1200px, Twitter 1024px

Batch Processing: Use consistent settings across multiple images for uniform results

Format Selection: JPEG for photos, PNG for graphics/logos, WebP for modern browsers

File Size Increase: If compression increases file size, try lower quality or different format

PNG Quality: PNG is lossless - quality setting only affects JPEG/WebP formats

Recompress: Try different settings and click "Recompress" to optimize results

Privacy First: All processing happens in your browser, no uploads required

Frequently Asked Questions

What's the difference between JPEG, PNG, and WebP?

JPEG is best for photos with many colors, PNG for images with transparency or few colors, and WebP offers the best compression for modern browsers while supporting both lossy and lossless compression.

How much can I compress without losing quality?

For most images, 80-85% quality provides excellent results with significant size reduction. Photos can often go as low as 70% while graphics and screenshots may need 90%+ to avoid artifacts.

Is my data safe when using this tool?

Yes, absolutely. All image processing happens entirely in your browser using JavaScript. Your images are never uploaded to our servers or transmitted anywhere.

What's the maximum file size I can compress?

You can compress images up to 10MB each, with a maximum of 10 files at once. For larger files, try reducing the image dimensions first or use desktop software.

Can I convert between different image formats?

Yes, you can convert images to JPEG, PNG, or WebP format during compression. Choose "Output Format" in settings to convert while compressing.

What happens to my images after compression?

Your images are processed locally in your browser and automatically cleaned up when you close the page. No data is stored on our servers.

Why did my file size increase after compression?

This can happen when converting formats (PNG to JPEG), using high quality settings, or with already optimized images. Try lowering quality or changing the output format.

Does quality setting affect PNG images?

No, PNG uses lossless compression, so quality settings only affect JPEG and WebP formats. PNG files maintain perfect quality regardless of the quality slider setting.

What's the best format for web use?

WebP offers the best compression for modern browsers (25-30% smaller than JPEG). For compatibility, use JPEG for photos and PNG for graphics with transparency.

How do I optimize images for fast loading?

Use JPEG with 80-85% quality, resize to appropriate dimensions (1920px max for web), and consider WebP format for modern browsers to achieve fastest loading times.
