About Imizer
Imizer is a set of free image tools. It converts, compresses, crops and resizes images, and removes, recolours or blurs backgrounds with AI, and it does almost all of that on your own device rather than on a server. This page covers who makes it, how it is paid for, and what happens to your files.

Who makes it
Imizer is built and maintained by The Media-Research Team, a small group of software developers. There is no account system, no login and no database of visitors or their files, which keeps the site simple to run and leaves nothing about you to lose. You can reach us at [email protected].
Why the tools run in your browser
Uploading a photo so that a server can turn it into a slightly different photo is a strange habit once you look at it. Your device already has everything needed to decode, edit and re-encode an image, and doing the work there means the file never travels, there is no queue, and nobody else ever holds a copy. It also means the converters keep working with your connection switched off once the page has loaded.
The trade-off is that the tools can only do what a browser can do. Batches are capped at five images because a decoded image takes about four bytes per pixel in memory, and a phone closes tabs that ask for too much. The AI background tools need an 84 MB model on your device, which costs a download the first time you use one.
The two tools that use a server
Browsers can display AVIF and ICO files but cannot create them. So the AVIF converter and the favicon generator prepare the image in your browser and send it to our own encoder, which holds it in memory for the length of the request and does not write it to disk, log it or keep it. Both pages say this before you use them, and the privacy policy sets out the detail.
How the tools are tested
Every tool is checked by downloading the files it produces and inspecting them, not by looking at the screen. That rule exists because the screen lies: our crop tool once drew a perfectly good selection while exporting the uncropped image, and only the downloaded file showed it. The figures quoted on the tool pages, such as a 584 KB test image coming back as a 75 KB WebP, come from those measured downloads.
The same habit shaped the background tools. The AI model used to come from its publisher’s CDN, which told a third party the address of every visitor who used it and made the first cut-out take nearly five minutes on a bad day; serving it from this site brought that to under half a minute. We also compared the 84 MB model against a version half its size before choosing it: the smaller one left almost eight times as many speckled, half-transparent pixels in the background.
How it is paid for
The tools are free and there is no paid tier. The plan is for advertising to cover the hosting costs, but there is no advertising on the site at the moment. We do not sell data about visitors, and the privacy policy lists the analytics the site does use.
