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 active 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 is temporarily unavailable while its processing engine is replaced with a fully auditable implementation.
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 and a small number of integrity-pinned libraries from third-party CDNs, so those providers can receive ordinary connection metadata when those resources load. StudioLimb currently loads no advertising scripts. The content of files processed by active tools is not sent to a StudioLimb server.
Why it is free
The free tools are supported by StudioLimb's optional digital products. Because processing happens on your device rather than on rented compute, the tools can remain available without an account or a usage quota.
