About StudioLimb
StudioLimb is a collection of free tools for people who design and build things for the web: CSS generators, image utilities, SVG editors, converters and reference tools. There is no account, no trial, and no paid tier gating the output.
Your files never leave your device
This is the part worth being precise about, because most free image tools work the other way around. When you drop a photo into a typical online compressor or background remover, the file is uploaded to that company's server, processed there, and sent back. A copy exists on a machine you do not control.
StudioLimb's image tools do the work in your browser. Compression, cropping, resizing, filters, watermarking and collage assembly all run through the Canvas and File APIs on your own machine. The background remover runs a neural network locally through @imgly/background-removal, which executes the model in the browser rather than calling an API.
The practical consequence: none of these tools contain a single upload call. You can verify that yourself — open any tool, open your browser's network panel, and process a file. You will see no request carrying your image.
What this does not mean. The site loads fonts from Google Fonts and serves advertising, so those third parties see that you visited a page, the same as on most of the web. What they do not see, and what no server sees, is the content of the files you process.
Why it is free
The tools are supported by advertising. That is the whole model. Because the processing happens on your device rather than on rented compute, running these tools costs close to nothing per use, which is what makes giving them away without a signup wall sustainable.
