Your Design, Your Way


Simax offers three ways to get a design onto your product. Upload your own logo or artwork in formats like AI, EPS, PDF, PNG, or JPG, or drag files straight from Google Drive or Dropbox. Prefer to start from scratch? Use our text editor to add custom type with full control over font, color, size, arc, and spacing.

If you don't have a design yet, our AI art generator creates original graphics from a simple text prompt. Just type a keyword like "mountain landscape" or "vintage sports logo," pick from the results, and drop it onto your product. All in under a minute.

Print-Ready Quality, Every Time


Great prints start with great files, and our builder is designed to get you there. Uploaded images can be enhanced with super resolution for sharper detail at any size, and our one-click background removal keeps your artwork clean and isolated on the garment.

The editor also guides you with dynamic design boundaries that adapt to each product type, whether it's a hoodie, polo, tank top, or quarter-zip, so your artwork always lands in a valid print zone. No guesswork, no reprints.

Frequently asked questions

What file formats can I upload for my design?

We accept AI, EPS, PDF, TIFF, PSD, JPG, and PNG files. For the sharpest results, we recommend vector formats like AI or EPS. You can upload directly from your device or import files from Google Drive or Dropbox.

How does the AI design generator work?

Enter a short description of what you're looking for: a concept, theme, or keyword, and our AI engine produces multiple design options instantly. You can also browse categories like Sports, Nature, Animals, or Music for inspiration. Select any result, and it's placed directly onto your product canvas, ready to position and resize.

Can I edit my image after uploading it?

Yes. The builder includes tools to remove or replace your image's background, crop and trim to focus on specific areas, adjust colors, and boost resolution with our super resolution feature. You can also resize, rotate, flip, and reposition the image on the product before finalizing.

How do I know my design is placed correctly on the product?

The editor displays dynamic boundary guides that change based on the product you've selected. These guides show you exactly where the printable area is, for example, left chest, right chest, or full back, and prompt you to keep your design within the safe zone so it prints accurately.
