Frequently Asked Questions
Is image resizing free?
Yes — completely free, no login, no watermark, no limits on usage.
Does my image get uploaded to a server?
No. All resizing happens in your browser using Canvas API. Your images never leave your device.
How many images can I resize at once?
Up to 20 images at a time. Each image can be up to 25 MB.
Which formats are supported?
You can upload JPG, PNG, WEBP, and GIF. You can download in JPG, PNG, or WEBP format.
Will resizing reduce my image quality?
Resizing to smaller dimensions generally maintains quality. The quality slider (for JPG/WEBP) lets you control the compression level.
Can I resize without changing the aspect ratio?
Yes — enable 'Maintain aspect ratio' and changing width will automatically update height proportionally.
