Our Promise
I built CompressImage.ca around one simple idea: your images should stay on your device. You should not have to upload private photos just to make them smaller.
- Never uploaded to our servers
- Never received by our infrastructure
- Never stored, cached, or backed up by us
- Never analyzed, scanned, or fingerprinted by us
- Never sold or shared with anyone
- Never used to train AI models
Why I built it this way
A lot of online image tools work by uploading your file to a server, processing it there, and then sending the result back. That can work, but it also means your image has to leave your device first.
I wanted CompressImage.ca to work differently. When you use one of the tools here, the image processing happens inside your own browser. The server sends you the tool, but your browser does the work.
That means I do not need to receive your files, and you do not need to trust me with them. The safer design is not “we promise not to look.” The safer design is “we never get the image in the first place.”
How it works
CompressImage.ca uses browser-based processing, including WebAssembly-powered image tools where needed. In plain English, that means image compression and conversion can run directly on your device at high speed, without sending your image to a remote server.
When you drop an image onto a tool:
- Your browser reads the file from your device.
- The image is processed locally in your browser.
- The optimized copy is created inside your browser.
- You download the finished file back to your own device.
- The image data is not uploaded to CompressImage.ca at any step.
There is no upload queue for your image, no cloud-processing folder, and no server-side copy waiting to be deleted later. The website is designed so the image tools do not need your files to leave your browser.
The difference at a glance
| Typical online image tool | CompressImage.ca | |
|---|---|---|
| Your image is uploaded | Usually | No |
| Copies may sit on a server | Often, at least temporarily | No |
| Server upload limits | Common | No server upload limit |
| Waiting for a processing queue | Possible | No upload queue |
| Can work after the tool loads | Usually no | Often yes |
| Who can see your image | The service may receive it | Only you |
You can check it yourself
I do not want this promise to be something you just take on faith. You can check what your browser sends over the network.
- Open one of the image tools.
- Press F12 to open your browser's developer tools.
- Go to the Network tab.
- Choose an image and run the tool.
- Watch the requests. The tool may load website files, but your image should not be uploaded.
This is the same basic method developers and security researchers use when they want to see what a website is sending. If image data were being uploaded, the Network tab would be the place to look.
What this means for you
- More privacy. Your personal photos, client images, IDs, documents, screenshots, and sensitive files stay on your device.
- No upload wait. Processing starts locally, so you are not waiting for a large file to travel to a server first.
- No server-side image storage. Since I do not receive your images, I cannot store them, inspect them, leak them, or sell them.
- No server upload cap. You are not limited by an upload endpoint, although your own browser, memory, and device still have practical limits.
- Better on slow connections. Once the tool has loaded, image processing can happen locally without sending the image across the internet.
What this promise covers
This promise covers the image files you choose inside the CompressImage.ca image tools. Those files are processed locally in your browser and are not uploaded to our servers.
Like most websites, CompressImage.ca may still load normal website files, security features, fonts, ads, or other page resources. Those are separate from your image files. Advertising or analytics providers, if used, do not receive your image files from CompressImage.ca. More detail is available in the Privacy Policy and Cookie Policy.
Built in Canada
CompressImage.ca is operated from Ontario, Canada. I built it to be simple, useful, and privacy-first: free image tools that do the job without asking you to hand over your files.
That is the promise: your images stay with you.
