Browse this task →| Criterion | BIRME Image upscaling 94/100 Seven-aspect task score BIRME is one of the rare free tools that runs AI super-resolution entirely client-side via in-browser WebGPU/WASM without requiring an account. In our live test, it upscaled a 1024px input to a full 2048x2048 watermark-free native PNG in 60.3s, achieving an edge correlation of 0.6668 that significantly outperforms traditional bicubic interpolation while providing uncompromising zero-upload privacy.

| Fixture findings | Under the 2048px standard anchor, BIRME's local WebGPU super-resolution outputs a 2048x2048 native PNG with 26.97 dB PSNR, 0.8897 SSIM, 0.6668 edge correlation (+17.9% over bicubic baseline), and 16.08 dB plate PSNR, completing in 60.3s purely offline on the client. | The tested 2× result had clear lettering without obvious artifacts, at 1024px. |
| Original historical observation | BIRME AI Enhance runs purely offline via browser WebGPU/WASM, upscaling 1024x1024 to 2048x2048 with an edge correlation of 0.6668, delivering significantly better detail than bicubic interpolation. | PSNR=27.08dB · SSIM=0.8862 (2x 1024×1024 unwatermarked PNG); Edge gradient correlation edge_corr=0.6080 (+4.24% over Bicubic); high-frequency recovery hf_ratio=0.4716 (+10.65%); Calibration plate PSNR=15.54dB: clean 'REALTEST 2026' typography with zero ringing artifacts in just 2.64s. |
