Frequently Asked Questions (FAQ)
The fastest method is using our dedicated percentage scale slider. Our advanced online photo resizer automatically handles the proportional calculation, allowing you to instantly scale the image (downsizing or upscaling) while maintaining the crucial aspect ratio. This is ideal for quickly preparing images for email or web upload.
The aspect ratio is the proportional relationship between the width and height. By locking it, our resize image tool ensures that when you enter a new value for one dimension (e.g., setting a new width in pixels), the other dimension (height) automatically adjusts. This preserves the original image's proportions, guaranteeing a professional output without any distortion.
While our platform is optimized for single-file precision to ensure the highest output quality, it currently does not support batch processing. For bulk image resizing online, we recommend processing files sequentially or considering a high-volume desktop application. We continuously work to enhance our free image resizer capabilities for future updates.
The optimal dimensions for website images depend on their placement (e.g., hero image, thumbnail, blog post). A common practice is to resize images to a maximum width of 1920px for full-screen banners, and generally keeping all images under 1500px on the longest side. Our tool allows you to change image dimensions precisely to fit any modern screen resolution.
