The tool reduces file size by removing redundant pixel data and applying compression algorithms. Lossy compression (JPG) discards some data; lossless compression (PNG) does not.
Typical compression reduces file size by 40 to 80 percent depending on the image content and the quality setting you choose.
No. Compression only reduces file size. The pixel dimensions (width and height) stay the same.
Lossy compression (JPG, WEBP) permanently removes some image data to achieve smaller sizes. Lossless compression (PNG, GIF) reduces size without any data loss.
80-85% quality is a good balance between file size and visual quality for most web images. Below 60% you may notice visible artefacts.
Yes. PNG compression is lossless, so transparency is fully preserved. File size reduction for PNG is typically 20-40%.
Aim for under 200 KB for most web images. Use WEBP format for the best compression. Use our tool to compress before uploading to your website.
