About Image Upscaler
The HAXTANX Image Upscaler enlarges JPG, PNG, and WebP images up to 4× with progressive stepped interpolation, detail-preserving sharpening, conservative noise reduction, and tone improvements. Processing runs 100% locally in your browser with zero file uploads, accounts, or watermarks.
How to use Image Upscaler
Upload or drop your image
Drag and drop any JPG, PNG, or WebP photo up to 30 MB. Your file is decoded locally without uploading.
Choose scale & enhance preset
Select your target scale factor (1.5×, 2×, 3×, or 4×) and fine-tune sharpness, noise reduction, and contrast.
Preview comparison & download
Inspect details using the interactive split slider, choose your export format, and download the full-resolution file.
Your images are processed directly in your browser
Unlike cloud-based conversion platforms that upload your files to remote servers, HAXTANX processes all transformations locally in memory via HTML5 Canvas and WebAssembly. Your photos, documents, and private location data never leave your device.
