Frequently Asked Questions

How do I resize an image online for free?
Upload your image to our free image resizer, enter the width and height in pixels (or choose a percentage), then click Resize Image. Your resized photo downloads instantly — no signup, no watermark, completely free.
Does resizing an image reduce its quality?
Making an image smaller keeps quality very high because our photo resizer uses high-quality resampling. Enlarging an image beyond its original size can look soft, so we recommend downscaling whenever possible.
Is it safe to resize photos on this website?
Yes. All image resizing happens locally in your browser using JavaScript. Your photos are never uploaded to any server, so your files stay 100% private.
What image formats does the image resizer support?
You can resize JPG, JPEG, PNG, WebP and GIF images. You can also change the output format to JPG, PNG or WebP while resizing.
Can I resize an image to a specific file size in KB?
Yes — first resize the dimensions here, then use our Compress Image tool and adjust the quality slider until the estimated size matches the KB size you need.
Can I resize images on my phone?
Absolutely. This image resize tool works on any device — Android, iPhone, tablet or desktop — right in your web browser with no app to install.
