Why ImgTool?
No upload
All processing happens in your browser. Your photos are never stored on a server or seen by anyone else.
No limits
There is no cap on file count or size. Process many images at once and download them as a ZIP.
Completely free
No sign-up, no payment, no watermark.
Fast
Several images are processed in parallel using your device’s CPU cores, and there is no upload to wait for.
How does it work without uploading?
ImgTool downloads its image-processing programs to your browser as WebAssembly and runs them on your device. Compression uses proven open-source encoders such as Mozilla’s MozJPEG, Google’s WebP encoder and OxiPNG. That is why your photos never need to be sent to a server, and why a slow connection never slows you down.
The full list of open-source software is on the Open Source Notices page, and details about the service and its operator are on the About ImgTool page.
Frequently asked questions
Is it really free?
Yes. Every tool is free to use without an account, and no watermark is added to your images.
Are my photos stored anywhere?
No. All image processing happens inside the browser you are using right now, and files are never sent to a server. When you close the page, your work is gone with it.
Does it work on my phone?
Yes. It works in modern mobile browsers such as Safari on iPhone, Chrome on Android and Samsung Internet. For many very large photos, a computer will be faster.
Can I process several images at once?
Yes. Add as many images as you like, then download them one by one or all together as a ZIP file.
