Our image compressor uses advanced algorithms to reduce file size while maintaining visual quality. It removes unnecessary metadata, optimizes compression levels, and can convert images to more efficient formats. You can adjust compression settings to balance between file size and image quality according to your needs.

We support all major formats: JPEG, PNG, GIF, WebP, and SVG. The tool can compress these formats and also convert between them (e.g., PNG to JPEG). For vector graphics (SVG), we offer specialized optimization that removes redundant code while preserving image quality.

The free version allows: 1) Single files up to 25MB, 2) Batch compression of up to 20 images at once, 3) Maximum total batch size of 50MB. Premium accounts get 100MB single files, 100-image batches, and 500MB total batch size. All compressed files are available for 24 hours after processing.

Some quality reduction is inevitable with lossy compression (like JPEG), but our tool uses smart algorithms to minimize visible quality loss. You can control this with quality sliders - higher values preserve more quality but result in larger files. For lossless compression (PNG), we remove unnecessary data without affecting quality.

Lossy compression (JPEG, WebP) permanently removes some image data for smaller files, with adjustable quality levels. Lossless compression (PNG, GIF) preserves all original data but typically can't reduce file size as much. Our tool automatically recommends the best method based on your image type and intended use.

For optimal results: 1) Use the preview feature to compare before/after, 2) Start with our recommended settings, 3) For web use, aim for 70-85% quality (JPEG) or try WebP format, 4) For print, use higher quality (90-100%), 5) Experiment with different formats to see which gives the best compression for your specific image.

Yes! Our advanced options include: 1) Setting exact pixel dimensions, 2) Scaling by percentage, 3) Constraining proportions, 4) Setting maximum width/height, 5) Cropping tools. Resizing before compression often yields the best file size reductions, especially for oversized images.

Absolutely. You can: 1) Upload multiple images at once, 2) Apply the same settings to all, 3) Or customize settings per image, 4) Download all as a ZIP file, 5) Save your preferred settings as presets. Batch processing maintains folder structure when downloading, and shows individual compression ratios for each file.

Our premium version includes: 1) Chroma subsampling optimization, 2) Progressive JPEG loading, 3) PNG palette reduction, 4) Metadata stripping (EXIF, GPS, etc.), 5) Intelligent quantization, 6) Selective blurring of low-detail areas, 7) Advanced WebP compression with alpha channel support.

This can happen when: 1) Converting from a highly compressed format (like JPEG) to PNG, 2) Using quality settings higher than the original, 3) Adding transparency to formats that didn't have it, 4) The image was already optimally compressed. Try different formats or lower quality settings if this occurs.

For pixelation issues: 1) Increase the quality setting, 2) Try a different format (WebP often handles compression artifacts better), 3) Avoid extreme resizing, 4) Use the "smoothing" option if available, 5) For text/images with sharp edges, consider PNG instead of JPEG, 6) Check if the original image was already low quality.

Common issues include: 1) File size exceeds limits, 2) Unsupported format, 3) Corrupted image file, 4) Browser extensions interfering, 5) Slow internet connection. Try: checking file properties, converting to a standard format first, using a different browser, or splitting large batches into smaller groups.
