Reduce image file sizes by up to 80% without sacrificing privacy. This browser-based image compressor supports JPG, PNG, and WebP files and runs every optimization step locally on your device. Unlike server-side compressors, your photos, screenshots, and client assets never leave the tab, which makes it safer for confidential projects and faster for day-to-day publishing workflows.

No. Every file you drop is re-encoded in a Web Worker inside this tab using the vendored browser-image-compression library. The compressed result is generated locally; nothing — original or compressed — is ever sent to a server.
JPG, PNG, and WebP for input. By default the compressor keeps each file in its original format; toggle Convert to WebP if you want smaller, modern output (WebP is supported by every current browser).
It depends on the source. JPGs typically shrink 30–70% at quality 70–85 with no visible loss; PNGs with photographic content can drop dramatically when converted to WebP. The before/after panel shows the exact saving per file.
Yes. Drop a folder's worth of images and they queue up. When more than one file is queued, the Download button switches to a bulk ZIP download (built locally with jszip); a single file goes straight to a direct download.
Yes — re-encoding a photo through this tool drops the embedded EXIF metadata, including GPS coordinates, camera model, and timestamps. That is usually what you want when posting an image publicly.
Many free compressors upload your images to a third-party server where the files may be logged, cached, or retained. This tool uses client-side processing only, so nothing is uploaded. That makes it safer for corporate assets, client work, and personal photos.
Yes, after the first visit. The compressor and the vendored libraries are cached by your browser, so you can drop images on a plane or a closed network and the queue still runs.
Drop JPG, PNG, or WebP files into the drop-zone. The browser re-encodes each file with the quality you choose, using the browser-image-compression library in a Web Worker. Nothing is uploaded — the original and the compressed copy both live only in memory on your device. Close the tab and they are gone.
