Free Online JPG Compressor
Large photo files slow down websites, fill up storage, and make emails bounce. LovePDFImg's Compress JPG tool reduces the file size of your JPEG images by re-encoding them at a quality level you control, so you can find the sweet spot between a small file and a sharp picture. Drop in one photo or a whole batch, drag the quality slider, and watch the before-and-after file sizes update for each image.
The compression happens using your browser's built-in Canvas API — the image is drawn to a canvas and re-exported as a JPG at the chosen quality, all without leaving the page. Because nothing is uploaded, this works well even for personal photos you'd rather not send to an unknown server. When you're done, download every compressed image at once as a ZIP file.
