An exported picture shows a chart but does not necessarily preserve editable cells, palette labels, and progress. Keep the project file as well as the version you want to print or share.
Choose the right format
The JSON project stores grid dimensions, cell colors, palette references, material settings, and completion marks. SVG is useful for a scalable chart image, while PNG gives a familiar raster image. CSV records the material estimate. These formats serve different jobs; a chart image is not automatically an editable project when imported again. Image import samples a picture into a new chart.
Keep a backup outside the browser
Local saving is convenient on one device, but browser data can be cleared and is not a cloud account. Download a JSON backup with a meaningful filename before major edits. The studio supports undo history for recent changes, but a downloaded file is a stronger checkpoint for a version you may want next week. Keep the chart export and material list with that version.
Track design changes
Changing dimensions, merging colors, or cleaning the chart can reset progress marks because the design has changed. If you have already started stitching, save the current project before editing. Compare the changed areas with the physical fabric rather than assuming previous completion marks remain accurate. The tool validates imported project dimensions and values, but it cannot verify that a saved chart matches work already stitched.
Download a JSON backup, then export the chart and material list from the same saved version.

Our guides offer general planning advice. Chart colors are digital approximations. Choose physical floss from a real color card or your own stash before a large project. Fabric and thread estimates describe full crosses with your entered stitch length and allowance. Backstitch, half stitches, unusual carries, and finishing need separate planning. We do not claim hands-on tests of products mentioned in buying guides.
