How to Resize Images in Bulk

  1. Upload: Drag and drop your JPG, PNG, or HEIC files into the box above.
  2. Select Settings: Choose a preset (like Instagram) or enter custom dimensions.
  3. Process: Click the button. Our tool runs in your browser, so it's instant.
  4. Download: Save your optimized images as a ZIP file.

Is it safe to upload my photos?

Yes. Unlike other sites, PixelBatch processes images locally on your device. Your photos are never uploaded to a server, making it safe for passports and legal docs.

Does it support HEIC?

Yes! We automatically convert iPhone HEIC photos to JPG or PNG so you can use them on Windows or the Web.

Will I lose quality?

You control the quality. Use our "Visual Comparison" slider to find the perfect balance between file size and sharpness.

Is this tool free?

Forever free. No sign-up required, no watermarks added (unless you choose to add your own), and no daily limits.
