Good to know
This tool is free without sign-up, with unlimited processing and exports within the displayed input limits.
- Enlarging an image does not recover missing detail. Output is limited to 40 million pixels and 16,384 pixels on either side.
- Choose Single file or Batch on this page. Both modes keep their own files and settings. Your tool access and export limits apply to both. Batch images use the same format, quality and size controls. Select files or a folder and download individual results or a ZIP.
- When aspect ratio is locked, each image fits inside the chosen width and height using its own proportions. Unlock it to apply exact dimensions to every image.
