Enlarge and Upscale Images Online
Online Image Upscaler — Enlarge Photos Without Losing Quality
Enlarge and upscale images online for free using high-quality resampling algorithms. Upload any image and increase its resolution by 2×, 3×, 4×, or up to 8× the original size, or specify exact target dimensions in pixels. This tool uses advanced interpolation filters to produce sharp, clean results when making images bigger.
Choose the Right Resampling Filter
Select from several professional-grade resampling filters to get the best results for your specific image type:
- Lanczos — produces the sharpest results with minimal ringing artifacts. Best all-around choice for photographs and detailed images.
- Mitchell — good balance between sharpness and smoothness. Great for portraits and graphics.
- Catmull-Rom — slightly sharper than Mitchell, excellent for high-contrast images.
- Cubic — smooth interpolation suitable for general purpose upscaling.
- Nearest Neighbor — preserves hard pixel edges without blending. Perfect for pixel art, game sprites, and retro graphics.
Supported Formats
Supports all major image formats: JPG, JPEG, PNG, WebP, AVIF, BMP, TIFF, HEIC, HEIF, GIF, JXL (JPEG XL), and SVG. The output maintains the same format as the input image. Enable the optional Sharpen after upscale setting to add an unsharp mask that enhances detail and reduces the soft look typical of enlarged images.
