Bildkompressor

Image compression reduces file size by removing unnecessary data while preserving visual quality. Our tool uses advanced algorithms to optimize the balance between file size and image quality, achieving up to 80% size reduction.

Quality settings control the compression level. Higher percentages (90-100%) maintain better image quality but result in larger files. Lower settings (70-80%) create smaller files with minimal visible quality loss. 70-90% is optimal for most web use.

Our compressor supports JPG/JPEG, PNG, and WebP formats for both input and output. You can convert between formats while compressing - for example, convert PNG to JPG for better compression ratios.

For photos, use 70-80% quality with JPG or WebP format. For images with text or graphics, use 85-95% quality. Enable target file size if you need files under a specific size limit. Use resizing for additional compression.

Yes! Upload up to 20 images at once for batch compression. All files will use the same settings, and you can download them individually or all at once when processing is complete.

Absolutely! All image compression happens directly in your browser using JavaScript. Your images never leave your device or get uploaded to any server, ensuring complete privacy and security.

Each image can be up to 50MB in size. You can compress up to 20 images simultaneously. These limits ensure optimal performance while handling most common use cases.

Yes! The image compressor is fully responsive and works perfectly on smartphones and tablets. The touch-friendly interface makes it easy to upload and compress images on the go.

Compression is a lossy process for JPG and WebP formats, meaning the original cannot be perfectly restored. We recommend keeping a backup of your original images. PNG compression is lossless, so PNG files can be decompressed to their exact original state.

WebP is generally the best choice for websites, offering 25-35% smaller files than JPG at the same quality. JPG is still excellent for photographs. PNG is best for images requiring transparency, while GIF is suitable for simple animations.

By default, compression only reduces file size without changing dimensions. However, our tool includes an optional resize feature that lets you reduce image dimensions for additional file size savings, which is ideal for web use.

Our tool compresses static images (JPG, PNG, WebP). For animated GIF compression, try our dedicated GIF converter tool which supports animation optimization and format conversion.
