What this tool produces

Increase dimensions using canvas resampling and a sharpening filter.

Input: Browser-decodable PNG, JPG or WebP; up to 50 MB. Output: PNG for PNG input, otherwise JPEG; 2x or 4x dimensions.

Walkthrough

  1. Select an image and choose 2x or 4x.
  2. Inspect the enlarged result before downloading.

Limitations and troubleshooting

  • No neural-network model or first-run AI download is used. Resampling cannot recover detail absent from the source.
  • 4x width and height require far more memory. Use the largest clean source available.

Keep your original. No fixed processing time, guaranteed output size or universal browser support is claimed.

Optional Google Analytics helps us understand page visits and tool results. File contents, filenames, passwords and text inputs are excluded from our tool events. Tools work with either choice. Privacy details
