Bulk resize images for products, websites and social media

Standardizing image dimensions makes product grids cleaner, thumbnails more consistent and social posts easier to publish. This free bulk image resizer processes several images with the same settings, so you do not have to resize each JPG, PNG, WebP or GIF separately.

Resize images in bulk

Add several files, apply one width, height and resize mode, and process the entire group together.

Use exact pixel dimensions

Enter a target width and height up to 8000 pixels for product photos, website graphics and marketing assets.

Preserve aspect ratio

Fit mode scales images proportionally without stretching and does not enlarge images that are already smaller.

Crop images to fill

Fill mode scales and center-crops each image to cover the requested canvas without leaving empty space.

Create common image sizes

Use presets for product images, thumbnails, Instagram posts and Open Graph sharing images.

Download one ZIP file

Save resized files individually or collect the full completed batch in a single ZIP archive.

How to resize multiple images online

  1. Add your images. Upload one or more JPG, PNG, WebP or GIF files using the file picker or drag-and-drop area.
  2. Enter the target dimensions. Set a width, height or both in pixels. Leaving one field blank resizes the image proportionally from the other dimension.
  3. Choose a resize mode. Use Fit to preserve the whole image, Fill to crop it to a fixed canvas, or Exact to stretch it to the requested dimensions.
  4. Resize the batch. The results show the original and completed pixel dimensions for every file.
  5. Download the images. Save individual resized files or download the complete group in one ZIP archive.

Fit, fill or resize to an exact size

Select the resize behavior that matches how the finished image will be used.

Fit: resize without distortion Preserves the complete image and its aspect ratio. The result fits inside the maximum width and height and is not enlarged.
Fill: scale and center crop Covers the full target canvas while preserving proportions. Extra content around the edges is cropped from the center.
Exact: stretch to dimensions Forces the image to the precise width and height. This can alter proportions and visibly distort the image.

Bulk image resizing questions

Can I resize multiple images at the same time?

Yes. Upload several supported images, choose one set of dimensions and a resize mode, and process them as a batch. You can then download the files separately or together in a ZIP.

How do I resize an image without changing its aspect ratio?

Select Fit mode. Fit scales the width and height proportionally so the image is not stretched. You can also enter only a width or only a height to calculate the other dimension automatically.

How do I crop several images to the same dimensions?

Enter both target dimensions and select Fill & Crop. Each image is scaled proportionally to cover the canvas and then cropped from the center to the exact requested size.

Does the image resizer enlarge small images?

Fit mode does not upscale images that are already smaller than the target dimensions. Fill and Exact modes can enlarge an image when necessary to create the requested canvas size.

Can I resize images for an online store?

Yes. The product and thumbnail presets are intended for standardizing ecommerce photography, although the ideal dimensions depend on the requirements and theme of the store where the images will be published.

Will transparent PNG and WebP backgrounds be preserved?

The resizer preserves transparency when creating PNG and WebP output. JPG images use a solid background because the JPG format does not support transparency.
