Frequently asked questions
Is this tool free?
Yes, it is 100% free with no sign-up, no watermark and no daily limit.
Are my files uploaded to your server?
No. The tool runs entirely in your browser using JavaScript. Your files never leave your device, so the tool is private and works even on slow connections.
Will the image get blurry?
Shrinking keeps images sharp. Enlarging beyond the original size can look soft, because no new detail can be created.
How do I resize an image without losing quality?
Reduce size rather than enlarge, keep the aspect ratio locked and export at high quality.
How do I resize a photo for Instagram?
Choose the Instagram preset (1080 × 1080 or 1080 × 1350) and download.
Can I resize images in bulk?
Yes, upload multiple images to resize them with the same settings.
