Image Resizer

How to resize an image

1. Drag your images into the box, or choose Browse files.
2. Tap a preset size, type your own width and height in pixels, or tick Make all sizes at once to get every preset in one ZIP.
3. Choose how the picture should fit: crop, fit inside or stretch.
4. Select Resize images, then download each file or use Download all.

Crop, fit inside or stretch?

• Crop to fill: the picture covers the whole size and the edges that do not fit are cut off. Best for social media posts.
• Fit inside: the whole picture is kept and the empty space is filled with a background colour.
• Stretch: the picture is forced to the exact size and people or objects can look squashed, so use it only when the shape barely changes.

Private and free

Resizing happens in your browser. Your images are not uploaded to ImgNexa, and there is no account or watermark.

Popular sizes and what they are for

The preset buttons cover the ten sizes people ask for most. They are common recommendations and platforms change them from time to time, so check the current guidance if you need a perfect fit.

• Instagram Post (1080 x 1350): a portrait feed post.
• Instagram Story (1080 x 1920): a full-screen vertical story or reel cover.
• Instagram Square (1080 x 1080): a classic square post.
• YouTube Thumbnail (1280 x 720): a 16:9 video thumbnail.
• YouTube Cover (2560 x 1440): channel banner artwork.
• Facebook Post (1200 x 630): a shared link or image post.
• Facebook Cover (820 x 312): a profile or page cover photo.
• LinkedIn Post (1200 x 628): an image shared in the feed.
• X Post (1200 x 675): a 16:9 image in a post.
• Pinterest Pin (1000 x 1500): a tall 2:3 pin.

Resizing without losing quality

• Making a picture smaller keeps it sharp. Making it bigger cannot add detail, so an enlarged picture looks soft.
• Start from the largest original you have, not from a copy that was already shrunk.
• Choose JPG for photos and PNG for graphics. Use Original to keep each file in its own format.
• Resizing also removes camera and location metadata, because the picture is redrawn in your browser.

Pixels, file size and why both matter

Resizing changes the number of pixels in a picture, and that is the biggest factor in file size. A photo from a modern phone can be 4000 pixels wide, while a blog column or a social post rarely needs more than 1200 to 2000. Reducing the width to what is actually displayed often shrinks the file by a large amount with no visible difference on screen.

Keep the proportions when you shrink a picture, otherwise people and objects look stretched. When a platform needs an exact shape, choose a preset that matches it, and use the fit option that suits the picture: crop to fill the frame, fit inside to keep everything visible, or stretch only when distortion does not matter.
