FAQ

Frequently Asked Questions

How do I resize an image to specific dimensions?

Upload your image, enter your desired width and height in pixels (px), percentage (%), or centimeters/inches, lock or unlock aspect ratio, and download your resized image.

Are my photos uploaded to an external server when resizing?

No. Resizing is performed directly in your browser using high-quality bicubic interpolation on HTML5 Canvas buffers. No files are uploaded.

Can I resize images by percentage instead of exact pixels?

Yes. You can scale down to 50%, 75%, 25%, or enter any custom scaling percentage.

How do I prevent images from stretching or distorting?

Keep the 'Lock Aspect Ratio' toggle enabled. Entering a new width will automatically calculate the proportional height to prevent distortion.

Which image formats can I resize?

You can resize PNG, JPG/JPEG, WebP, GIF, SVG, BMP, and ICO files.

Can I batch resize multiple images at once?

Yes. You can upload multiple images and apply uniform dimensions or percentage scaling across the entire batch with one click.

Can I upscale small images without making them blurry?

The tool utilizes advanced lanczos/bicubic resampling to smooth pixelation when enlarging images, though native high-resolution sources are always recommended.

Does resizing change DPI or print resolution?

You can specify print dimensions in centimeters (cm) or inches (in) along with standard 72, 150, or 300 DPI for physical printing.

Will PNG transparency be preserved when resizing?

Yes. The alpha channel transparency is preserved completely without turning backgrounds black or white.

Can I resize social media photos to exact platform dimensions?

Yes. Convenient presets are provided for Instagram posts and stories, YouTube thumbnails, Facebook covers, Twitter headers, and LinkedIn banners.

Does this tool work on mobile devices?

Yes, it works smoothly on iPhone, iPad, and Android mobile browsers.

Does resizing add watermarks to my photos?

No. Your output images are 100% clean with zero watermarks or ads.

Can I resize images while offline?

Yes. Once the page is loaded, the resizer runs completely offline without internet connectivity.

Is this image resizer completely free to use?

Yes, 100% free with unlimited image resizing and no sign-up requirements.

Why resize in the browser rather than desktop software?

It requires no installation, launches instantly, works on any device, and keeps your private photos safely on your computer.
