Resize images for Instagram, Facebook, LinkedIn and YouTube
Every platform crops pictures differently, and a wrong size means blurry uploads or awkward crops. This free image resizer changes the width and height of JPG, PNG and WebP files while keeping the aspect ratio, and includes ready-made presets for the most popular social media formats.

How to resize a photo online
- Upload one or more images.
- Select a preset or type a custom width and/or height in pixels.
- Click Resize images. The picture is scaled to fit inside the size you chose without stretching.
- Download the resized images, or all of them as a ZIP.
Resize vs. compress
Resizing changes the number of pixels; compressing changes how much data each pixel needs. For the smallest possible file, resize first and then use the image compressor. To hit a strict limit such as 100KB, use Compress to Exact KB.
The resizer works locally in your browser: no upload, no account, no watermark and no limit on the number of images.
FAQ
Will resizing crop my image?
No, the image is scaled to fit within your chosen dimensions while keeping its original aspect ratio — nothing is cropped.
Only need to reduce file size, not dimensions?
Use the Image Compressor instead — it keeps the original pixel size.
