About ImgCruncher
Free, private, browser-based image tools. No uploads, no sign-ups, no watermarks.
ImgCruncher is a free suite of 26 image tools that run entirely in your browser: compression, resizing, conversion, cropping, watermarking and more. Every tool works the same way: your image is processed on your own device, and it never touches a server.
The site was born out of a simple frustration. Shrinking a photo or converting a format usually means uploading your file to a stranger's server, waiting in a queue, and getting a watermarked or limited result unless you pay. Most of these tasks never needed a server in the first place, so ImgCruncher was built to do them where they belong: on your device. The first version went live in spring 2026 with a handful of tools and has grown to 26.
Our principles
Three rules every tool on this site follows, no exceptions.
Private by design
Every tool runs in your browser. Your images never touch a server, so there is nothing to store, log or leak.
Honest about limits
Where a tool has a real weakness, its page says so. We would rather undersell than surprise you with a bad result.
Free, with no gates
No accounts, no daily caps, no watermarks, no paid tier. The site is funded by unobtrusive ads and nothing else.
What you get
The short version of what lives here.
- 26 image tools: compress, resize, convert, crop, watermark, inspect and more
- Chain steps into one pass: resize, convert and compress in a single download
- Exact size targets, like compress this to 100 KB, found automatically
- Batches with a single ZIP download, processed one by one on your device
- Works offline once loaded, install it like an app if you want
- A blog where every guide is tested for real, with actual measured numbers
How it works under the hood
Every tool here runs in your browser using the HTML5 Canvas API and the FileReader API. When you drop in an image, it loads into your browser's memory, gets processed on your own device, and the result is handed straight back to you. The file never travels to a server, because there is no server in the loop for the actual work.
That is not a privacy promise you have to take on trust. It is structural. If the processing happens in your browser, there is nothing for the site to store, log or leak.
You can verify this yourself: open your browser's network tab while you use a tool and watch. Your image never goes out.
What is working, and what isn't
The compression, resizing, conversion and cropping tools are solid, fast and in daily use. The honest picture includes the weaker spots too. The background remover handles plain, high-contrast backgrounds well but struggles with busy ones and fine hair, because doing that properly needs a heavy AI model that cannot run comfortably in a browser yet. The upscaler sharpens and enlarges with good interpolation, but it cannot invent detail that was never captured. Where a tool has a real limit, its own page says so rather than overpromise.
What is coming
Tools are added as needs appear and as users ask for them. Recent additions were chaining several steps into a single pass, compressing to an exact target size, and a film-style grain filter. Next on the list is bringing that chained pipeline to more of the tools and smarter handling of large batches. The site is actively worked on, not parked.
