Frequently Asked Questions
How do I resize an image without distorting it?
Enable the "Lock Aspect Ratio" option. Set either the width or height and the other dimension will adjust automatically to maintain the original proportions.
What is the maximum file size I can resize?
There is no strict limit, but very large images (over 20MB) may be slow to process depending on your device. All processing happens in your browser.
Can I resize multiple images at once?
Yes — select multiple files at once and each will be resized to your chosen dimensions and made available for individual download.
Will resizing reduce image quality?
Enlarging an image beyond its original size will cause some loss of sharpness. Reducing size generally preserves quality well, especially with the WebP output format.
Are my images uploaded to a server?
No. All resizing happens in your browser using the HTML5 Canvas API. Your images never leave your device.
