Frequently Asked Questions
How do I resize an image without losing quality?
Our tool utilizes high-precision bicubic multi-step resampling. When downsizing, it eliminates jagged edges and aliasing. When upscaling, it interpolates pixels smoothly.
What does Lock Aspect Ratio mean?
Locking the aspect ratio preserves the original proportional relationship between width and height, preventing your image from looking squished or stretched.
What are the Fit Modes (Proportional, Crop to Fill, Stretch, Pad)?
When resizing to fixed dimensions (like 1920×1080), Proportional fits inside the bounds, Crop to Fill zooms and crops excess margins, Pad adds background letterboxing, and Stretch forcefully fits exact dimensions.
What format should I download my resized image in?
WebP offers the smallest file sizes with superior quality. JPG is ideal for photography, and PNG is best for graphics with transparent backgrounds.
