Questions

  • What does compression mean?

    Compression reduces file size by removing unnecessary data. Lossy compression removes some image data (may reduce quality), while lossless keeps all data (larger files but identical quality).

  • Will compression reduce quality?

    Quality depends on the compression level. At 80%+ quality, most people can't see the difference. For web images, 60-80% quality is often acceptable.

  • What file formats work?

    JPG, PNG, GIF, and SVG. Each format has different compression behaviors - PNG uses lossless, JPG uses lossy, SVG is optimized via code reduction.

  • Can I compress multiple images at once?

    Yes, you can upload up to 20 images and compress them all at once. Download as individual files or as a ZIP archive.

  • Is my image data secure?

    Absolutely. All compression happens in your browser - your images are never uploaded to any server.
