Image Compression for Web Optimization

Image compression is a critically important website optimization process that reduces image file sizes without significant quality loss. Modern compression algorithms can reduce file sizes by 60-90%, significantly improving site loading speed and SEO metrics.

Why is it important to compress images for websites?

Images make up to 80% of total web page size. Unoptimized images slow down site loading, worsen Core Web Vitals metrics and negatively impact SEO ranking in Google and Yandex. Proper image compression can increase loading speed by 3-5 times and significantly improve user experience.

Types of image compression

• JPEG compression: Optimal for photographs and complex images with lots of colors
• PNG compression: Ideal for images with transparency and simple colors
• WebP format: Modern format with better compression while maintaining quality
• HEIC/HEIF conversion: Full support for converting Apple HEIC format to JPG, PNG or WebP with automatic optimization and compression

What is HEIC format?

HEIC (High Efficiency Image Container) is a modern image format developed by Apple for iPhone and iPad. It provides better quality at a smaller file size compared to JPEG, but is not supported by all browsers and platforms.

How does HEIC conversion work?

Our compressor automatically detects HEIC files and converts them to JPEG format before processing. The conversion happens directly in your browser without uploading files to the server. After conversion, the image is automatically optimized and compressed according to your settings.

Benefits of HEIC conversion

• Compatibility: Converted images work on all platforms and browsers
• Optimization: After conversion, images are automatically compressed for web use
• Security: All processing happens locally in your browser
• Speed: bulk conversion and processing of many files at once

SEO Benefits of Image Optimization

• Core Web Vitals: Improvement of LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift) metrics
• Search Ranking: Loading speed is a ranking factor in Google and Yandex
• Mobile Optimization: Compressed images load faster on mobile devices
• User Experience: Fast loading reduces bounce rate and increases time on site

Benefits of Our Image Compressor

• Intelligent Compression: Automatic selection of the optimal algorithm for each image type
• Quality Settings: Flexible adjustment of compression level with preview of the result
• Batch Processing: Simultaneous compression of multiple images
• Metadata Preservation: Option to preserve EXIF data and color profiles
• Security: Processing takes place on secure servers with automatic cleanup

Image Compression Recommendations

• Quality 85-95%: Optimal balance between quality and file size
• Image Size: Avoid images wider than 1920px for web use
• File Format: Use WebP for modern browsers with JPEG fallback
• Lazy Loading: Combine compression with lazy loading for maximum optimization

Adding copyright to images

The copyright feature allows you to automatically add watermarks, logos, QR codes, or other elements to your images while optimizing them. This is a useful tool for copyright protection, branding, and marketing.

Why do you need copyright?

• Copyright protection: Copyright helps protect your images from unauthorized use and indicates authorship.
• Branding: Overlaying a logo or company name on an image increases brand awareness
• Marketing: QR codes on images allow users to quickly navigate to your website or get additional information
• Professionalism: Copyrighted images look more professional and organized

What can be copyrighted?

Different types of images can be used as copyright:

• Company logo: Your corporate logo for branding and recognition
• QR code: QR code for quick access to your website, social networks or additional information
• Avatar: Your photo or avatar to personalize images
• Watermark: Text or graphic watermark with website name, company name, or copyright symbol
• Other elements: Any other image you want to add to your photos

How to use the copy function?

1. Enable the "Add copyright" option in the Compressor settings
2. Upload a copyright file (logo, QR code, avatar or other image) - the file is downloaded locally to your browser
3. Choose the placement of the copyright: in the corners, in the center, or in the form of a pattern (checkerboard, solid)
4. Adjust the copyright size (from 2% to 100% image width)
5. Set margin and transparency for optimal appearance
6. Upload and optimize images - copyright will be automatically added to all photos

Copyright patterns

Our compressor supports different types of copyright placement:

• Single accommodation: Copyright is placed in one place (corners, center, side positions)
• Chess pattern: The copyright is repeated in a checkerboard pattern throughout the image.
• 45 degree pattern: Copyright is placed at a 45 degree angle in a checkerboard pattern
• Solid pattern: Copyright covers the entire image evenly

Practical tips

• Use transparency 70-90% so that the copyright does not interfere with the perception of the main image
• The 5-15% copy size is usually optimal for most cases
• For QR codes, the recommended size is 10-20% and placement is in the lower right corner.
• Logos are best placed in corners with an indent of 2-5% from the edge.
• Patterns are ideal for protecting large photo collections
