KerfCanvas

File and job limits

A file that looks small can still contain a very large image or thousands of shapes. KerfCanvas checks the real amount of work before it starts.

What the website checks

Each tool has tested limits for file size, image pixels, number of shapes or lines, memory use, and expected running time. You can cancel longer jobs without losing the source file.

When a job is too large

Most jobs run on this device. If a job is too large or uses something the website does not support, KerfCanvas explains the limit and may suggest Desktop. It never uploads your file in the background.

What is available now

The website includes 200 tools organized into 33 pages. Very complex tracing, irregular-shape arranging, unsupported G-code, and machine control require Desktop or stop with a clear explanation.
