Is this image resizer really free?

Yes, our image resizer is completely free with no usage limits. All processing happens in your browser — we don't need server resources, so there's no cost to pass on. No sign-up or credit card required.

What image formats are supported?

We support JPEG, PNG, WebP, and BMP input formats. The output preserves the original format (JPEG or PNG) with optimized quality settings for the best balance of file size and visual quality.

Is my image data private and secure?

Absolutely. Your images are processed entirely in your browser using the Canvas API. No files are uploaded to any server, and no data leaves your device. Once you close the tab, all processed data is cleared from memory.

What is the maximum image size I can resize?

You can upload images up to 50 MB in size and resize them to dimensions up to 8192x8192 pixels. For most social media and web use cases, this is more than sufficient.

Can I resize images on my phone?

Yes, our image resizer works on any device with a modern web browser, including smartphones and tablets. The interface adapts to smaller screens for a comfortable mobile experience.

Does resizing affect image quality?

Our tool uses high-quality image smoothing (bicubic interpolation) to maintain sharpness when scaling. Scaling down typically preserves quality well. Scaling up beyond the original resolution will show some quality loss, as with any resize tool.

Can I also compress images to reduce file size?

This tool focuses on changing image dimensions. If you also need to reduce file size, try our free image compressor which optimizes quality while reducing file weight.
