When you change the size of a picture, you run the risk of making it look blurry or pixelated. Follow these three rules to maintain crisp image quality:
Always Scale Down, Never Scale Up: Shrinking a large image to a smaller size preserves clarity because the tool simply discards excess pixels. Stretching a small image into a larger size forces the tool to invent pixels, which results in a blurry, pixelated final product.
Choose the Right File Format: Use JPEG for photographs to keep file sizes small while maintaining smooth color transitions. Use PNG for graphics, logos, and screenshots to preserve sharp lines and transparent backgrounds.
Watch the Compression Slide: Most free resizers feature a quality slider before you export. Setting the quality between 80% and 90% drastically reduces the file size while keeping the visual degradation completely invisible to the human eye.
