Frequently Asked Questions
How does image compression work?
Our image compressor uses advanced algorithms to reduce file size by optimizing image data while preserving visual quality. It removes unnecessary metadata, optimizes color palettes, and applies smart compression techniques. The tool analyzes each image to find the optimal balance between file size and quality.
What compression ratio can I expect?
Compression ratios vary by image type and settings. Typically, you can achieve 50-90% file size reduction. Photos compress more (60-90%) while graphics with fewer colors compress less (30-70%). JPEG images usually compress better than PNG for photographs, while PNG is better for graphics with text or sharp edges.
Will compression affect image quality?
Our smart compression maintains visual quality while reducing file size. You can control the quality level - higher compression means smaller files but potentially lower quality. Preview before downloading to ensure satisfaction. Most users find 80-85% quality provides excellent results with significant file size savings.
What image formats are supported?
We support JPEG, PNG, WebP, and GIF formats. You can also convert between formats during compression for additional optimization (e.g., PNG to JPEG for photos). WebP format typically provides the best compression while maintaining quality, making it ideal for web use.
Is there a file size limit?
The tool can handle large images, but performance depends on your device. For optimal performance, we recommend images under 20MB. All processing happens locally in your browser for privacy and security. Very large images may take longer to process but will still work.
Can I compress multiple images at once?
Currently, the tool processes one image at a time for optimal quality control. This allows you to fine-tune compression settings for each image. You can use the tool multiple times for different images, ensuring each one gets the perfect compression level for your needs.
Is image compression reversible?
No, image compression is not reversible. Once an image is compressed and quality is reduced, the lost data cannot be recovered. Always keep a copy of your original high-quality images before compressing. We recommend downloading the compressed version and comparing it before deleting originals.
Does compression work for all types of images?
Yes, but results vary by image type. Photographs with gradients compress well with JPEG. Graphics, logos, and screenshots with sharp edges and text work better with PNG. Complex images with many colors benefit more from compression than simple graphics with few colors.
How does this help with website performance?
Compressed images load faster, reducing page load times and improving user experience. Smaller file sizes mean less bandwidth usage, faster mobile loading, and better SEO rankings. Google considers page speed as a ranking factor, making image compression essential for website optimization.
Is my image data safe and private?
Absolutely! All image compression happens entirely in your browser using client-side JavaScript. Your images are never uploaded to any server, meaning they never leave your device. This ensures complete privacy and security for your photos and graphics.
