Image Upscaler - Quick Cheat Sheet
Resampling uses the browser's canvas engine. High maps to imageSmoothingQuality='high'; Nearest disables smoothing (good for pixel art and logos).
Scale: pick 2x/3x/4x or a custom factor (e.g., 1.5x). Use Max output side to cap very large results.
Output: choose PNG (lossless), JPEG, or WebP. For JPEG/WebP, adjust Quality (80-95 is typical).
Privacy: processing is local; metadata (EXIF) is removed by design when using canvas export.
GIFs: only the first frame is processed.
Tips & notes
Nearest-neighbor is ideal for pixel graphics; for photos, use High quality.
Very large upscales may consume more memory-use the Max output side to avoid crashes on low-RAM devices.
PNG preserves sharp edges; JPEG/WebP can be much smaller for photos.
