Compression reduces file size so pages load faster, inboxes stay under limits, and storage costs drop. Lossy JPEG compression discards some detail that human vision barely notices when quality is set thoughtfully.
This ToolLane compressor resamples the longest edge when it exceeds your chosen maximum, then encodes JPEG at your quality setting—all without sending pixels to a remote server.
How to Use This Compressor
- Pick quality and max edge before or after loading an image. Changing sliders recompresses the current file automatically.
- Add your image via Choose image or drag-and-drop. Supported types include JPEG, PNG, WebP, and other common raster formats your browser can decode.
- Review the preview and the before/after size hint, then download the JPEG when you are satisfied.
Why Use ToolLane?
- Private processing on your device.
- Free with no account.
- Simple controls for quality and resolution.
