Resize images precisely and easily
Every platform has an ideal image size: Instagram prefers square 1080×1080, stories need 1080×1920, Facebook covers and link previews use 1200×630, and government portals sometimes require ID photos at exact dimensions. This tool lets you set dimensions precisely in pixels or as a percentage, keeping proportions automatically so images never look stretched.
How to use it
- Choose or drop an image; its original dimensions and size appear.
- Type the width or height you need — with “Keep aspect ratio” on, the other side is calculated automatically.
- Or enter a percentage, such as 50% to halve the dimensions.
- Or pick one of the social media presets.
- Click “Resize & download”.
Fit modes explained
- Stretch: the image is stretched to the exact new dimensions. Only suitable when the ratio is about the same.
- Crop to fill: the image is scaled to cover the whole frame and the overflow is trimmed evenly from the edges. Best for social posts.
- Fit with padding: the whole image is shown inside the frame with transparent or white padding — useful when nothing may be cropped.
Does enlarging hurt quality?
Downscaling never makes an image blurry — it just makes it lighter and faster to load. Upscaling far beyond the original can't add real detail and may look soft, so we suggest staying under 150%. We use the highest smoothing quality your browser offers for the best possible result.

Keep “Keep aspect ratio” on and enter only the width or height; the other side is calculated at the same ratio.

Can I resize a transparent PNG?
Yes. Choose “Same format”, PNG or WebP to keep transparency.
