- [Can I print a logo made with ChatGPT?](https://svgproof.com/guides/print-chatgpt-logo): Yes, small: a ChatGPT PNG prints sharp up to about 3-5 inches. For shirts, signs and vinyl you need a vector. Sizes, checks and how to convert.
- [What file format does a printer need for a logo?](https://svgproof.com/guides/printer-file-format): Printers want a vector: SVG, PDF, EPS or AI. Which to send for shirts, signs, vinyl and cards, and how to get one from a PNG or an AI logo.
- [Should I auto-trace my AI logo or pay for a redraw?](https://svgproof.com/guides/auto-trace-or-redraw): Auto-trace a flat AI logo in seconds; pay a designer to redraw when it has texture, bad letters or 3D effects. How to tell which, and what each costs.
- [The print preflight checklist for an AI logo](https://svgproof.com/guides/ai-logo-print-checklist): Eight checks before you send an AI-made logo to a printer: format, size, text, background, colors, thin lines, gaps and rights.
- [Why was my image refused?](https://svgproof.com/guides/why-image-refused): SVGProof refuses photos, textured art and files over 5 MB or 17 megapixels, because tracing them gives unusable files. What each refusal means and what to do.
- [How do I convert PNG to SVG with an API?](https://svgproof.com/guides/vectorize-api): One POST with the image, the SVG in the response. curl, Python and Node examples for the SVGProof vectorize API, with batch, pricing and limits.
