Basic costs $6 for two months with 500 pictures per month; Standard costs $12 for six months with 1,000 per month; Premium costs $22 for twelve months with 2,000 per month. All three paid packages allow up to 16x enlargement and 50MB files, with priority processing, parallel jobs and batch mode. Package duration and monthly image allowance are separate. Offline processing is available with an account, including Free. If you submit without logging in, keep the browser open while processing. The official API is available to paid members after login; check its account-specific limits before building an automated workflow. Compare VanceAI for an online credit-based workflow or a separate Windows application. The June 23, 2026 terms name Guangzhou Datu Technology Co., Ltd. as the operator and leave ownership of uploaded images with the user. You must have the rights needed to process them. The privacy policy says uploads are not used to train models and are removed from active systems within 24 hours after processing on Free, or 72 hours on Premium. It also describes cloud storage and content moderation, so this is a cloud service rather than local-only processing. Save results before the retention window ends. |
