Bigjpg vs Quizwhiz
Side-by-side comparison · Updated September 2026
| Description | Bigjpg enlarges existing artwork, illustrations and photographs with AI reconstruction. It can smooth noise and redraw edges, but cannot guarantee that reconstructed details match the original scene. Check faces, linework, lettering and product details at the final viewing size. It is an image upscaler, not a text-to-image generator. Free allows 20 pictures per month, up to 4x enlargement and a 5MB upload. 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.
