Frequently asked questions

How do I resize an image for free?

Drop your images into the tool above, choose either percentage or pixel mode, set your desired size, then click Resize Images. Your resized files download instantly — no account needed.

Are my images uploaded to a server?

No. All resizing happens entirely in your browser using JavaScript. Your images never leave your device and are never sent to any server.

Can I resize multiple images at once?

Yes. You can drop up to 30 images at a time (500MB total) and they will all be resized with the same settings in a single batch.

What does the aspect ratio lock do?

When the aspect ratio lock is enabled in pixel mode, changing the width automatically adjusts the height (and vice versa) to keep the image proportions identical to the original. This prevents stretching or squishing.

What image formats are supported?

Squish Files supports all common image formats your browser can display, including JPEG, PNG, WebP, GIF, BMP, and SVG. The output format matches the original.
