Free Online Image Compressor

Reduce image file sizes without sacrificing quality. Fast, secure, and completely free – no uploads to our servers required.

Why Use an Image Compressor?

Large image files can significantly slow down your website, leading to poor user experience and lower search engine rankings. Whether you’re a blogger uploading photos, a developer optimizing assets, or a content creator sharing visuals, compressed images are essential for:

• Faster loading times: Smaller files mean quicker page loads
• Better SEO rankings: Search engines favor fast-loading websites
• Reduced bandwidth usage: Save on hosting costs and mobile data
• Improved user experience: Visitors won’t wait for slow images to load
• Storage savings: Keep more images in the same space

How This Tool Works (Step by Step)

Our image compressor is designed to be simple yet powerful. Here’s how to get the best results:

1. Upload Your Images

Drag and drop your images directly onto the upload area, or click “Browse Files” to select multiple images at once. We support all major formats including JPEG, PNG, WebP, and AVIF.

2. Adjust Compression Settings

Fine-tune your compression with our advanced controls:

• Set quality levels from 10% to 100%
• Choose output format (Auto, JPEG, WebP, PNG, AVIF)
• Resize images by setting maximum width/height
• Strip EXIF data for privacy and smaller file sizes

3. Preview and Download

Each compressed image shows you the exact file size reduction and compression percentage. Preview your results before downloading, and delete any images you don’t need to keep your workspace organized.

Key Features

What sets our compressor apart from other tools:

Aggressive Compression Mode

Enable “Extra compress” for maximum file size reduction. This mode automatically selects the most efficient format (AVIF when supported, otherwise WebP) and applies additional optimization techniques perfect for web use.

Target File Size

Need your images under a specific size limit? Enter your target in KB, and our tool will automatically adjust quality settings to meet your requirements while maintaining the best possible visual quality.

Transparency Preservation

Unlike many compressors that strip transparency, our tool intelligently preserves alpha channels when needed, ensuring your logos and graphics maintain their transparent backgrounds.

Benefits for SEO & Website Speed

Google’s Core Web Vitals make page speed a critical ranking factor. Optimized images directly improve your Largest Contentful Paint (LCP) scores, leading to better search visibility. When combined with other optimization techniques – like using a Free SEO Audit Tool to identify additional improvements – compressed images become part of a comprehensive speed optimization strategy.

Studies show that a 1-second delay in page load time can reduce conversions by up to 7%. By compressing your images, you’re not just improving technical metrics – you’re directly impacting your bottom line.

• Use quality settings around 70-75%
• Enable aggressive compression
• Choose WebP or AVIF format

For 100KB Targets (Blog Images)

• Keep width under 1200px
• Use quality settings 75-85%
• WebP format offers best balance

For 200KB Targets (Hero Images)

• Maximum 1920px width for most displays

Frequently Asked Questions

Is my data safe when using this tool?

Absolutely. All compression happens directly in your browser – no images are ever uploaded to our servers. Your files remain completely private and secure on your device.

What’s the difference between quality settings?

Lower quality settings (30-60%) create much smaller files but may show visible compression artifacts. Higher settings (80-90%) maintain near-original quality with moderate size reduction. Start with 70% for most web images.

Should I always use the newest formats like AVIF?

While AVIF offers superior compression, browser support is still growing. WebP provides excellent compression with broader compatibility. Use “Auto” format selection for the best balance.

Can I compress images for print?

This tool is optimized for web use. For print materials, you’ll want to maintain higher quality settings (90%+) and avoid aggressive resizing to preserve detail at print resolutions.

Why strip EXIF data?

EXIF data includes camera settings, GPS coordinates, and other metadata that increases file size. Removing it protects privacy and reduces file sizes by 5-15KB per image.
