Drop a JPG file below and this tool re-encodes it to a smaller size instantly, entirely inside your browser — no upload, no install, no sign-up. JPG (JPEG) is the most common photo format on the web, using lossy compression that trades a small amount of detail for a much smaller file.
Photos straight from a phone or camera are often 3-10MB — far larger than needed for web pages, email, or messaging. Lowering the quality setting re-encodes a JPG with more aggressive compression, usually cutting file size dramatically before quality loss becomes visible. Typical size reduction with this tool: 40-70%, depending on the image and, for lossy formats, the quality setting you choose.
