How to resize an image for social media
- Choose or drag in a photo. It loads instantly — nothing is uploaded.
- Select the platform size you need, or enter a custom width and height.
- Pick Crop to fill for full-bleed images, Fit to keep the whole picture with a coloured border, or blurred background for a polished look on Stories.
- Adjust the crop position if faces or text are being cut off, then download.

Tips for sharp social images
- Start with a bigger photo. Shrinking keeps images sharp; enlarging a small image makes it blurry.
- Use 4:5 on Instagram. Portrait posts take up more of the feed than square ones.
- Keep text away from edges. Profile photos are shown in a circle and banners are cropped differently on phones and desktops.
- Use JPG for photos and PNG for graphics with text. Then shrink the file with our image compressor if needed.
- YouTube thumbnails must be under 2 MB. JPG at 1280×720 is usually well below that.
Frequently asked questions
Is my image uploaded to a server?
No. The image is resized with your browser's built-in canvas, so it never leaves your device.
What is the best image size for Instagram?
1080 × 1350 pixels (4:5 portrait) for feed posts and 1080 × 1920 (9:16) for Stories and Reels.
Will resizing reduce quality?
Making an image smaller keeps it sharp. Making it much larger than the original can look soft, because the extra pixels have to be invented.
Can I resize on my phone?
Yes. The tool works in mobile browsers on Android and iPhone. On iPhone, tap and hold the downloaded image to save it to Photos.
