Does Resizing Reduce Image Quality?
It depends on the direction:
- •Making an image smaller — minimal quality loss, usually not noticeable
- •Making an image larger — can cause blurriness since you are adding pixels that were not there before
For best results, always start with the highest resolution version of your image and resize down, never up.
Tips for Best Results
- •Keep aspect ratio locked — this prevents your image from looking stretched or squished
- •Use PNG for graphics — PNG preserves sharp edges for logos and illustrations
- •Use JPG for photos — JPG gives smaller file sizes for photographs
- •Check file size after resizing — a smaller image should also have a smaller file size
