Frequently Asked Questions

How many images can I resize at once?

Our batch image resizer supports uploading up to 100 images simultaneously. For optimal performance and browser stability, we recommend batches of 50-100 images at a time. If you have more images, you can process them in multiple batches. All images in a batch are processed with the same settings, ensuring consistency across your entire image collection.

Will batch resizing reduce image quality?

Our batch resizer uses high-quality algorithms to maintain image quality during resize operations. When downsizing (making images smaller), quality is generally preserved well. When upsizing (making images larger), some quality loss may occur as new pixels must be created. We use 92% JPEG quality by default for the best balance between quality and file size.

Can I resize images to different formats in the same batch?

Yes! You can upload mixed formats (JPG, PNG, WebP) in the same batch and resize them all at once. All output images are converted to JPEG format for consistent file sizes and compatibility.

How do I download all the resized images?

After batch processing completes, you have two download options: download all images as a single ZIP archive (recommended for large batches) or download individual images one by one using the download button next to each file. The ZIP option is fastest and most convenient, automatically packaging all resized images into one file.
