Frequently Asked Questions
Will resizing affect image quality?
Enlarging images can reduce quality (pixelation). Reducing size generally maintains quality. Our tool uses high-quality bicubic resampling for the best results.
What is aspect ratio lock?
Aspect ratio lock maintains the original proportions when you change one dimension. If you change width, height adjusts automatically to prevent stretching or squishing.
What dimensions should I use for social media?
Common sizes: Instagram Post: 1080×1080, Story: 1080×1920, Facebook Post: 1200×630, Twitter Post: 1200×675, LinkedIn Post: 1200×627, YouTube Thumbnail: 1280×720.
