Supports JPG, PNG, WebP
Large images are the single biggest cause of slow web pages, and slow pages cost you visitors and search ranking. The Image Compressor reduces the file size of your JPG, PNG, and WebP images while keeping them looking sharp, so your pages load faster and your storage stays lean. Drop in an image and get back a smaller version you can download in seconds. Everything happens in your browser — your images are never uploaded to a server.
That in-browser processing is what sets this tool apart from many compressors. Since your files never leave your device, you can compress private photos, client work, or unpublished designs without handing them to an unknown server. Close the tab and nothing remains.

How to use the Image Compressor
Select or drag an image into the tool. It compresses the file automatically and shows you the result along with the size reduction achieved. Preview it to confirm the quality meets your needs, then download the compressed image. Repeat for as many images as you need — there is no account and no daily limit.
Features
It compresses JPG, PNG, and WebP formats, reduces file size significantly while preserving visual quality, and shows the before-and-after size so you can see the savings. Because it runs entirely in your browser, compression is fast, completely private, and works offline once the page has loaded.
Common use cases
Web developers and site owners compress images before uploading to keep pages fast and improve Core Web Vitals. Bloggers shrink photos to fit upload limits. E-commerce sellers optimize product images for faster catalogs. Anyone emailing photos or attaching them to documents uses it to stay under size limits, and designers use it to prepare lightweight assets for handoff.
How it works
The compressor re-encodes your image using the browser's built-in canvas and image APIs, reducing file size by optimizing how the pixel data is stored and, for lossy formats, fine-tuning the quality level to remove data the eye is unlikely to notice. Because the work is done locally, your original file is never transmitted. For photographs, JPG or WebP usually gives the smallest size; for graphics with sharp edges and few colors, PNG or WebP is often the better choice.
