Image Compressor
Compress JPEG, PNG, and WebP images in your browser, with adjustable quality and optional maximum dimensions.
LOCAL TOOL: Your image is decoded and compressed in this browser. It is never uploaded to WhateverTools. JPEG and WebP use adjustable lossy quality; PNG is lossless, so the quality slider does not change PNG compression.
Reduce image file size without handing the image to a server.
WebP and JPEG can trade a small amount of visual detail for a much smaller file. You can also set optional maximum dimensions, which is often the biggest size reduction when an image is larger than it needs to be for a website, email, form, or upload limit.
Choose WebP for small files, JPEG for broad compatibility, or PNG when lossless pixels matter.
Converting a transparent image to JPEG replaces transparency with white. PNG re-encoding may not make an already optimized PNG smaller; reducing dimensions or choosing WebP is usually more effective.
