Resize an image for an X post
X's timeline favors 16:9: post that ratio and the preview shows your full image instead of an algorithmic crop of it. 1600 × 900 hits the ratio with enough resolution for the expanded view.
This page opens the local resizer preset to 1600 × 900. Cover mode center-crops to fill; contain letterboxes the whole image if cropping is off the table.

How it works
Select an image to see its current dimensions.
Enter a width/height or percentage, or pick a platform preset (each shows its exact pixels).
Choose fit behaviour: contain, cover (center-crop), or stretch.
Preview the resulting dimensions, then export.
What the tool does
- Resize by exact pixels, percentage, or preset
- Contain, cover, and explicit stretch modes
- Presets for common social and document sizes, labelled with exact dimensions
- High-quality multi-step downscaling for sharp results
- Upscale warning before enlarging beyond the source resolution
How the result is verified
The exported image is re-decoded and its pixel dimensions are compared to your requested dimensions before download is offered.
Frequently asked questions
Why did X crop my image weirdly?
Non-16:9 uploads get an automatic preview crop that follows the platform's saliency logic, not your composition. Supplying 1600 × 900 sidesteps it — the preview is your image.
Does this help image quality on X?
Somewhat. X always re-encodes, but an image already at display ratio and size takes exactly one recompression with no extra scaling, which keeps text and edges cleaner.
