Shrink JPG/PNG file sizes by adjusting quality, right in your browser. 100% free, no sign-up — your file never leaves this browser tab.
Image Compressor lets you compress an image entirely inside your browser, with no software to install and no account to create. Like every tool on Techsinghge Smart Tools, it's built around cleaning up and shrinking a file so it's faster to send, store, and open, and it works the same way whether you're on a laptop, a Chromebook, or a phone.
Under the hood, Image Compressor takes one or more JPG or PNG images and hands back smaller image files at your chosen quality. Your file is loaded directly into this page's memory using JavaScript — nothing is transmitted to a server, which means there's no upload wait, no file-size cap tied to a paid plan, and no copy of your document left sitting on someone else's storage once you're done.
Shrinking photos before attaching them to an email is one of the most common reasons people reach for this tool, but it works just as well for reducing image sizes for faster-loading website pages. If you need a related step before or after this one, check the related tools further down the page — every tool on this site is designed to slot into the same drag-and-drop workflow.

Your one or more JPG or PNG images stays on this device the whole time — nothing is uploaded, logged, or stored on a server.
Processing happens right in this browser tab, so there's no upload progress bar, no server queue, and no processing fee.
Because Image Compressor runs locally, teams handling sensitive paperwork — legal, HR, healthcare admin, finance — can use it without the compliance questions that come with uploading documents to a third-party server. And if you only need it for a single one-off task, it's just as useful with zero setup and nothing to remember to delete afterwards.
Reduction varies by image content, but photos often shrink significantly at moderate quality settings with little visible difference.
