Frequently Asked Questions
Are my images uploaded to any server?▼
No. All image resizing is performed 100% client-side in your web browser using HTML5 Canvas. Your photos never leave your device.
How does the aspect ratio lock work?▼
When the aspect ratio lock is enabled (the default), changing either the width or height will automatically recalculate the other dimension to preserve the original image proportions without distortion.
Can I resize by percentage?▼
Yes. Switch to the "By Percentage" tab to scale your image down (e.g. 50%, 75%) or up (e.g. 150%, 200%) with instant dimension calculation.
Which image formats are supported?▼
You can upload PNG, JPEG, WebP, GIF, and BMP images. You can export the resized image in your choice of PNG, JPEG, or WebP.
Is there any watermark or file size limit?▼
There are no watermarks, no registration, and no artificial file size limits. Resizing is completely free and private.
