UsePNG encourages friends to upload the work to our site. ( When the copyright owner to file an infringement allegations UsePNG will engage in the investigate, the infringing works will be deleted after the infringement was confirmed.)
Images on UsePNG must have at least 500*500 resolution. A higher resolution is always the better choice.
Please refrain from upscaling too small images, because of unacceptable blurring. PNG format will be great. The images your upload need a transparent background. Upload as more as you can, unlimited on UsePNG.
