Quick answer
Does a live preview use a credit?
No. Live previews are always free. Only a finished conversion uses a credit, and a failed or canceled one costs nothing.
When do my credits renew?
Your conversion credits renew on the 1st of each month, at 00:00 GMT. Live previews never use one.
The detail
These are starting points, not promises, and we expect to raise them as the app matures and leaves beta.
| What | Limit | Why |
|---|---|---|
| Conversions | 250 per month | Renews on the 1st at 00:00 GMT. A failed or canceled conversion costs nothing. Live previews are free and never count. |
| Background removal | 100 per hour | This counts cutouts, not adjustments. Switching Remove background on for an image runs an AI model once, and that is what costs you one. Dragging the Sensitivity slider afterwards does not count, and neither does an edit with Edit background. The slider re traces the cutout Filafy already has, and never re runs the model. Drag it very fast and Filafy asks you to wait a few seconds. Cutting out a different image is a new one. |
| Live previews | 90 per minute | Generous enough to drag a slider freely. One preview renders at a time per account. |
| Filament import | 10 per hour | Each check matches your whole spool list from 3D Filament Profiles against a catalogue of over 11,900 filaments, which is heavier than it looks. The first summary, each change to Match by color only, across brands, and the final import each count as one. |
| Issue reports | 20 per hour | Keeps the report form from being used as a firehose. |
| Upload size | 25 MB image · 50 MB model | Images are JPG, PNG or WebP; iPhone HEIC photos and SVGs convert in your browser first. Models are STL, OBJ or 3MF. |
| Colors per print | Up to 24 | Your own Max colors setting can be lower. This ceiling is what a slicer can paint. |
| Images per print | Up to 10 | They share one style, one palette and one credit; see Many images on one face. |
| Print size | 5–1000 mm per side | A model marked Any size also stays inside your printer’s bed. A model file keeps its own size. |
| My models | 20 models · 250 MB | A kept model is deleted 30 days after you last use it. Each one is one upload, up to 50 MB. |
| Ask questions | 50 per day | You can ask the How To Guide this many questions each day when you are signed in. The count starts again at 00:00 GMT. After the last question, the guide gives basic answers from its own search until then. |
If you hit a limit, Filafy tells you at the point you hit it. The live preview does it more quietly. It stops refreshing for a moment and shows a short note, rather than interrupting you.
