Free Image Resizer

How to resize an image

1. Drop one or more photos onto the box above, or click to browse your device.
2. Pick a platform preset (like Instagram Post or Etsy Listing), or type an exact width and height in pixels.
3. Choose how to fit: Crop to fill keeps the frame full, Fit with padding keeps the whole image and adds a background colour, or Stretch forces the exact size.
4. Pick an output format (JPG, PNG or WebP) and quality, then click Resize.
5. Download a single image, or grab the whole batch as a ZIP.

Get the exact size every platform wants

Every social network and marketplace has its own preferred image dimensions, and uploading the wrong size means your photo gets awkwardly cropped, stretched, or compressed. The Image Resizer fixes that by letting you match the exact pixel dimensions each platform expects — either from a one-click preset or by typing your own width and height.

Because everything runs locally in your browser, you can resize a whole folder of product photos in seconds without waiting on an upload, and your images never leave your device. That makes it ideal for Etsy and Amazon sellers preparing listings, social media managers sizing posts for Instagram and Pinterest, and anyone who just needs a profile picture at the right dimensions.

Tip: for photographs, JPG at around 90% quality gives the best balance of sharpness and small file size. For logos, screenshots, or anything with hard edges and text, choose PNG to keep it crisp.
