Will resizing make my image blurry?

Enlarging an image beyond its original size can cause some blurriness since pixels are interpolated. Reducing image size generally maintains sharpness. Using the appropriate resampling method helps minimize quality loss.

Can I resize multiple images at once?

Yes, you can resize images one at a time quickly by uploading each image and applying the same dimensions. Batch resizing features allow you to process multiple images with consistent settings.

What is the aspect ratio lock?

When the aspect ratio is locked, changing the width automatically adjusts the height (and vice versa) to maintain the original proportions, preventing stretched or squashed images.

What output formats are supported?

You can save resized images as PNG, JPG, WebP, BMP, or GIF regardless of the original format. You can also adjust the quality level for lossy formats like JPG and WebP.

Is there a maximum image size I can resize?

There is no hard limit, but very large images (e.g., over 50 megapixels) may be slow depending on your device. Most common photo sizes work smoothly.

Are my images sent to a server?

No. All resizing is done entirely in your browser using the HTML5 Canvas API. Your images never leave your device.
