Image resizer FAQ
How do I resize an image to 1080×1080?
- Upload your file, choose the Square preset (1080×1080), then download. Keep aspect ratio locked if you want proportional scaling from one side first.
Will my photo look stretched?
- Keep aspect ratio locked when changing one side — the other updates automatically. Unlock only when you need exact non-proportional pixels.
What presets are included?
- Square 1080×1080, social portrait 1080×1350, story 1080×1920, and HD 1920×1080. These are common sizes, not official platform specs.
Is the resizer free?
- Yes. Resize images online for free in your browser — no account required for this tool.
