Tostadora supports images in both JPG and PNG format. Both formats will produce great results if the image uploaded has at least the minimum resolution or higher.


  • The JPG format supports millions of colours.
  • Most digital cameras save their images as JPGs.


  • PNG graphics contain an alpha channel for transparency and allow you to save graphics with transparent backgrounds.
  • Most graphic design programs (such as Adobe Photoshop) let you create PNGs.

GIF, TIFF, BMP, PDF, PSD or Word formats are not supported. GIF, TIFF, BMP and PSD can be converted to JPG or PNG with most image editing programs (such as Adobe Photoshop).

Note: Tostadora does not accept vector graphics such as AI, SVG, etc.. These graphic files must be rasterised to be uploaded here (the vectors must be converted to bitmaps). They can be opened directly with Adobe Photoshop, then saved as JPGs or PNGs, ready to be uploaded to Tostadora.

Important: The maximum width for user uploaded designs is 24 cm (JPG or PNG).

With slow connections, it is possible that your upload may "time out" before fully uploading the image.
