Tick <strong>Compress to a maximum size</strong>, pick 20, 50, 100, 200 or 500 KB or type your own limit, and drop the image.

Very large images (over about 50 megapixels) can be slow on phones because everything happens on your device.</p><h3>Will compressing reduce the quality?</h3><p>JPG and WebP compression removes details you usually cannot see; at 75% quality most people cannot tell the difference.

JPEG is best for photos, offering lossy compression that reduces file size by averaging similar colors and patterns. This method, using discrete cosine transform (DCT), achieves notable size reductions with minimal visual quality loss, although extreme compression can cause artifacts.

JPEG (Joint Photographic Experts Group)

PNG offers lossless compression via the DEFLATE algorithm (LZ77 + Huffman coding), ensuring no quality degradation. It's great for images that require transparency or sharp details, like graphics and logos, though file sizes can be larger than JPEG.

PNG (Portable Network Graphics)

WebP, designed by Google, combines both lossless and lossy compression for small, high-quality files. It uses advanced predictive coding to reduce size, making it efficient for web usage without sacrificing image clarity.

WebP (Web Picture)

BMP files are uncompressed and store every pixel’s color data directly, resulting in large files but perfect quality. BMP is rarely used online but ideal for editing or use cases needing original quality without compression.
