Full capability guide
Resize without accidental distortion
Resize each source by pixels, percentage or longest edge with explicit fitting and enlargement rules.
Three sizing modes
Use exact dimensions, a relative percentage or one longest-edge limit across mixed-size batches.
Contain, cover or stretch
Contain preserves the full image, cover crops edges to fill the canvas, and stretch changes proportions only when selected.
Background and presets
Use transparent or solid contain backgrounds with Square, Portrait, Landscape, Story, HD and Social presets.
High-quality batch control
Every source is calculated independently with optional no-upscale protection, per-file reprocessing and high-quality resampling.

Resize versus crop
Contain places the full rectangular photo inside the square without distortion. Cover fills the square by cropping the outer edges. Stretch changes the proportions and is available only when explicitly selected. Use the crop tool when you need precise control over the composition.
Choose dimensions before exporting
This page starts with the standard 1080 by 1080 square. The width and height remain editable, so the same resizer can prepare portrait or landscape assets. Keep important text and faces away from the edges where different app previews may crop the image.
Enlarging a small source to 1080 pixels cannot recreate detail. Start with the largest original available, crop it to the intended shape, then resize once for the cleanest result.
| Layout | Dimensions | Aspect ratio |

| Landscape post | 1080 × 566 | About 1.91:1 |
