Frequently asked questions
What social media sizes are supported?
Instagram Post (1080x1080), Instagram Story (1080x1920), YouTube Thumbnail (1280x720), Twitter Post (1200x675), Facebook Cover (820x312), and LinkedIn Banner (1584x396). You can also enter any custom dimensions.
Can I maintain the aspect ratio?
Yes, aspect ratio locking is on by default. Click the lock icon between the width and height inputs to toggle it. When locked, changing one dimension automatically adjusts the other.
Will resizing reduce image quality?
The tool uses high-quality resampling (bicubic interpolation) to minimize quality loss. Upscaling beyond the original dimensions may result in some softness.
Are my images uploaded anywhere?
No. All resizing happens locally in your browser using the Canvas API. Your images are never uploaded or stored.
