Free Online Image Resizer - Resize Images Instantly

Q: Is this image resizer really free?

Yes! Our image resizer is 100% free with no hidden fees, watermarks, or account requirements. You can resize unlimited images.

Q: Are my images uploaded to your servers?

No! All image processing happens directly in your browser using Canvas API technology. Your images never leave your device, ensuring complete privacy.

Q: What's the maximum file size I can resize?

You can resize images up to 25MB. This limit is based on browser memory, not our servers (since we don't use servers for processing).

Q: Can I resize images for Instagram?

Absolutely! We have presets for Instagram Posts (1080x1080), Instagram Stories (1080x1920), and all major social media platforms.

Q: Will resizing reduce image quality?

When you downsize images (make them smaller), quality remains excellent. Upsizing can introduce softness - for AI-powered upscaling with quality enhancement, try our AI Image Upscaler.

Q: What formats can I export?

You can export as JPEG (best for photos), PNG (best for graphics with transparency), or WebP (best for web optimization).

Q: How do I maintain aspect ratio when resizing?

Enable the 'Maintain aspect ratio' toggle. When active, changing width automatically adjusts height proportionally (and vice versa).

Q: Can I batch resize multiple images?

Currently, you can resize one image at a time. For batch processing and advanced AI enhancement, check out our premium AI Image Upscaler.

Resize your images to any dimension in seconds. Our free online image resizer works entirely in your browser - no upload, no signup, no watermarks. Perfect for social media, websites, and print.
