Image Resizer

Resize images in batches by pixels or percentage, with aspect ratio lock and local export.

Image Resizer

The image resizer changes image dimensions in batches directly in the browser. You can resize by exact pixels or by percentage, keep aspect ratio, prevent upscaling, and export the results without uploading original files.

How do you use it?

  1. Upload one image or a batch of images into the queue.
  2. Choose pixel mode for exact dimensions or percentage mode for proportional scaling.
  3. Adjust width, height, scale, aspect ratio, upscale prevention, and output format.
  4. Start processing, review the previews, then download single files or one ZIP archive.

Why use this tool?

  • Save time on repetitive manual resizing work
