Free online image compressor for JPG, PNG, WebP, and other images locally in your browser, preserving the original format by default with optional WebP output
When WebP is off, JPG exports as JPG, PNG exports as PNG, and WebP exports as WebP. The original file is kept when no safe compression is available.
Local Worker + OffscreenCanvas is used first. Images are not uploaded.
Upload images to compress automatically, compare previews, and download individual files or a ZIP.
