Image Tools FAQs
What is the difference between resizing and compressing an image?
Resizing changes pixel dimensions. Compression changes how image data is stored and can affect quality or size. A portal may require you to adjust both.
Should I crop before resizing a photo?
Crop first when you need a particular composition or aspect ratio, then resize to the required dimensions. Review the result so important content is not cut off.
Why did transparency disappear after conversion?
Some output formats do not support transparent pixels. Choose a format that supports transparency and inspect the downloaded image against a contrasting background.
Can making an image larger restore missing detail?
Increasing dimensions creates more pixels but does not reliably recover original detail. Start from a higher-quality source when sharp text or fine features matter.
How do I prepare an image for an upload portal?
Check the portal’s required dimensions, aspect ratio, format and maximum bytes. Adjust the image, then verify the actual downloaded file against all four requirements.
