Get your smaller JPEG, at the quality you chose
This tool runs the compression itself inside your browser using JavaScript — your photo never leaves your device. That also means you see the exact result before committing to it: drag the quality slider and the preview updates instantly, alongside the new file size, so you're never guessing what you'll get.
You choose the output format: JPEG for the smallest possible file (no transparency support), or WebP, which typically compresses smaller than JPEG at equal visual quality and preserves transparency if your source PNG has it.
It depends on the quality level you choose and the image itself. The tool re-encodes the image as a JPEG at your chosen quality (10-95%), and you can preview the result live before downloading, so you can find the smallest file that still looks acceptable to you.
Lower quality settings introduce more JPEG compression artifacts, which can show up as blur or blockiness at very low settings. The live preview shows you exactly what you'll get before you download, so there are no surprises.
Yes. You can upload JPG, PNG, or WEBP, and choose your output format too — JPEG for the smallest file size, or WebP, which usually compresses even smaller than JPEG at the same visual quality and keeps transparency if your source image has it.
No. Compression happens entirely inside your browser using JavaScript. Your images are never sent to a server.
