FREQUENTLY ASKED
Yes! Our Bulk Image Resizer is 100% free to use. There are no hidden fees, subscriptions, or limits on the number of images you can process.
No. Your images are processed locally and are not uploaded to any external server. No data is transmitted anywhere.
You can input JPEG, PNG, WebP, BMP, GIF, and AVIF images. For output, you can choose from JPEG, PNG, WebP, or BMP. Format conversion is handled automatically.
For lossless formats like PNG, quality is preserved. For JPEG and WebP, you can control the compression quality with a slider (0–100%). We default to 85% which provides an excellent balance between quality and file size.
There's no hard limit. We process images in parallel (up to 4 at a time) and free memory after each image to handle large batches gracefully.
Yes! The tool is fully responsive and works on mobile. However, processing large batches of high-resolution images may be slower on mobile devices due to hardware limitations.
EXIF data includes camera info, GPS location, timestamps, and other metadata embedded in photos. When enabled (default), this data is automatically removed during processing.
