Frequently Asked Questions
Q. How many images can I process at once?
We recommend up to 500 images per batch. Devices with 8GB+ RAM can handle up to 1000 images smoothly.
Q. Can I apply different settings to different images?
BatchPix applies one global setting per batch for consistency. If you need multiple sizes, please run separate batches.
Q. Are EXIF data (metadata) kept after resizing?
This is toggle-controlled. Default is "keep" to preserve camera info; select "strip" to remove location and date for privacy.
Q. What is the best setting for Instagram uploads?
We recommend 1080x1080 resolution at 85% JPG quality. This avoids Instagram's own heavy re-compression artifacts.
Q. Does it support cropping or adding margins?
Yes. "Fill" mode crops from the center to fit exact dimensions, while "Fit" maintains the aspect ratio and adds letterboxes.
