Frequently Asked Questions
Can I resize multiple image formats simultaneously?
Yes. Img Resizer supports uploading and batch-resizing JPG, PNG, WEBP, and BMP image files in one queue.
What is aspect ratio locking?
Locking the aspect ratio automatically calculates the proportional height when you change the width (or vice versa), preventing your photos from looking distorted or stretched.
Are my images uploaded to external servers?
No. All image resizing, cropping, and canvas operations take place 100% locally inside your web browser. Your photos stay strictly on your local machine.
Can I export all resized images as a ZIP file?
Yes. Once batch processing completes, you can download all modified images at once inside a single ZIP archive.
