Frequently Asked Questions
Will resizing affect image quality?
Making images smaller generally preserves quality well. Making images larger can reduce quality because the software must create new pixels. For best results, start with the largest original image available.
What is aspect ratio and why does it matter?
Aspect ratio is the proportion between width and height. A 4:3 aspect ratio means for every 4 units of width, there are 3 units of height. Keeping this ratio prevents your image from looking stretched or squished.
What dimensions should I use for social media?
Common sizes include: Instagram posts (1080x1080), Facebook cover (820x312), Twitter header (1500x500), LinkedIn banner (1584x396). Check each platform current guidelines as these can change.
