Make the file fit.
ToolImage helps you compress images to a target size, resize dimensions, and convert JPG, PNG, and WebP files. The core tools run locally in your browser, so your image stays on your device while you work.
Private image tools for everyday files
Use image compression when a file needs to fit an upload limit, image resizing when a project calls for exact pixels, and image conversion when a destination needs JPG, PNG, or WebP. Each tool is designed for practical work without an upload queue or an account requirement for the core workflow.
Resize images
Set exact dimensions or preserve the original aspect ratio.

- Choose an image from your device.
- Set a target size, dimension, or output format.
- Process the result locally in your browser and download it when ready.
Supported input formats include JPG, JPEG, PNG, and WebP. Local processing means the image content does not need to travel to a ToolImage image-processing server.
Good to know before you begin
Are my images uploaded to a server?
No. ToolImage processes supported images in the browser on your own device. Your file does not need to travel to a server for compression, resizing, or conversion.
Can I compress an image to 20 KB?
Yes, you can request 20 KB. When that target would severely affect image quality, ToolImage creates the smallest practical version and explains the result.
Which formats can I use?
ToolImage currently supports JPG, JPEG, PNG, and WebP files.
Will this work on my phone?
Yes. ToolImage is a responsive browser application designed for modern mobile, tablet, and desktop browsers.
