Frequently asked questions
- Is there a maximum image size?
- The tool handles images up to around 50 MP. Very large images may be slow on older devices due to browser memory limits.
- Can I resize to a percentage instead of pixels?
- Yes. Enter a percentage value and the tool calculates the new pixel dimensions based on the original image size.
- Will resizing to a larger size improve quality?
- No. Upscaling a raster image makes it larger but cannot add detail that was not there originally. For AI upscaling, use a dedicated tool.
- Does it preserve EXIF metadata?
- EXIF metadata is stripped during browser-based canvas operations. If you need to preserve metadata, use a desktop image editor.
