Bulk Image Resizer

Resize a whole folder of photos in one go. Images are handled one after another so your phone does not freeze.

Your file is processed on your device. Nothing is uploaded.

Very large photos use a lot of memory. If your phone gets slow, try 20 to 30 images at a time. For one photo with an exact KB target, the Photo Resize 20 KB / 50 KB / 100 KB tools give finer control.

How to use

  1. Choose many images at once.
  2. Pick a size preset or enter your own.
  3. Optionally set a maximum file size in KB.
  4. Tap Resize all, then download each file or the ZIP.
