Your images never leave your browser. Everything is processed locally with JavaScript — zero server uploads.
4x upscaling uses two sequential 2x passes for significantly sharper results than a single 4x jump.
Upscaled images are saved as lossless PNG to preserve every detail. No compression artifacts added.
SammaPix uses advanced browser-based algorithms to intelligently upscale your images. The tool analyzes pixel patterns and applies high-quality interpolation to increase resolution while preserving sharpness. Everything runs directly in your browser — your images are never uploaded to any server.
You can upscale images up to 4x their original resolution. For example, a 500x500 image becomes 2000x2000 at 4x. We recommend 2x for most use cases as it provides the best balance between size increase and quality retention. 4x is great for small thumbnails or icons that need to be enlarged significantly.
SammaPix uses multi-pass upscaling with high-quality smoothing to minimize blur. For 4x upscaling, we apply two sequential 2x passes which produces significantly sharper results than a single 4x jump. The output quality depends on the source image — higher quality originals produce better upscaled results.
SammaPix supports all major image formats: JPEG/JPG, PNG, WebP, GIF, AVIF, and HEIC. The upscaled output is always PNG to preserve maximum quality without any lossy compression artifacts.
Yes! Free users get 5 upscales per day with images up to 1500px. Pro users ($9/month) get 100 upscales per day with no size limits, plus access to all 25 SammaPix tools with higher limits.
Low-resolution images look pixelated when displayed on modern high-DPI screens. Whether you need to enlarge a product photo for your online store, upscale an old family photo, or increase the resolution of a thumbnail for printing, SammaPix helps you enhance image quality directly in your browser.
Unlike server-based upscalers that require you to upload your images, SammaPix processes everything locally. Your photos never leave your device, ensuring complete privacy. The upscaled output is saved as lossless PNG, so no additional compression artifacts are introduced.
