About UnoIMG
What UnoIMG Is
UnoIMG is a collection of practical, no-nonsense image utilities: format converters, compressors, croppers, blur and effect tools, and specialized viewers for modern formats like HEIC and GIF. Every tool is designed to do one job well and to stay out of your way.
There are no accounts to create, no files to upload, and no hidden limits on the things that matter. Whether you need to shrink a photo for the web, turn a PNG into a WEBP, or simply open a file your operating system cannot, the tool you need is one click away.
How Our Tools Are Built and Tested
Every UnoIMG tool is built in plain HTML, CSS, and JavaScript, with no accounts, no installs, and no artificial caps. Before a tool goes live it is tested in real browsers against real files.
Tools that users report as broken are fixed or rebuilt rather than left to decay. Image formats and browsers keep changing, so a tool that worked last year is re-verified rather than assumed to still work. The result is a toolkit you can rely on, not a pile of abandoned widgets.
Everything Runs in Your Browser
The one rule every tool on UnoIMG follows is simple: your images never leave your device. When you convert a picture or compress a photo, the work happens locally in your browser using JavaScript and the Canvas API. Nothing is uploaded, stored, or seen by us.
This is not a privacy promise you have to take on faith — it is an architecture you can verify yourself. Open your browser’s developer tools, switch to the Network tab, and use any tool: you will see no outgoing request carrying your data. Disconnect from the internet and the tools keep working, because there is no server in the loop.
We built it this way because the images people process are often exactly the ones that should never travel: private photos, client work, and documents with sensitive content. Client-side processing removes that risk entirely instead of managing it.
Free Means Free
No sign-ups, no trials, no watermarks, and no “pro” tier holding back the useful features. UnoIMG stays online through lightweight, unobtrusive advertising — that is the entire business model, and your images are not part of it.
Because your files never reach our servers, they cannot be monetized, analyzed, or leaked. Free here means free, not “free until you need the thing you came for.”
