How the Social Media Image Resizer works
Each platform enforces its own dimension sets, post ratios, cover bands, story verticals, and the tool maps your image onto the exact target size, handling the aspect-ratio conversion so important content stays inside the frame. Resizing is canvas-based and instant, and because your images, often brand or personal material, are never uploaded, the process is private by design.
Limits to keep in mind
Extreme aspect changes crop or letterbox content; keep the focal point centered so it survives the conversion.
Frequently asked questions
What size is an Instagram square post?
1080 by 1080 pixels is the standard; the tool fills that automatically when selected.
Will resizing reduce quality?
Downscaling preserves detail well; avoid stretching small images up to large dimensions.
Are my brand images uploaded?
No. Every resize runs locally in your browser.
