FAQ
Will resizing blur text?
Downscaling is usually sharp; extreme upscales may soften details.
Can I batch resize?
Batch mode is planned — today, process images one at a time.
Does EXIF data remain?
Exports are new PNG/JPG files from the canvas.
Can I use percentages?
Calculate target pixels externally or adjust width/height fields.
Is there a max resolution?
Limited by browser memory; very large images may need pre-compression.
