Frequently Asked Questions

Does this tool upload my images anywhere?+

No. All resizing happens directly in your browser using the Canvas API. Your images never leave your device.

What image formats are supported?+

You can upload JPEG, PNG, WebP, and GIF files. Output is available as JPEG or PNG.

What does "maintain aspect ratio" do?+

When enabled, changing the width automatically updates the height proportionally (and vice versa), so your image is never distorted.

What is the maximum image size I can resize?+

There is no enforced limit, but very large images (above 10 MB) may be slow to process depending on your browser and device.

Can I resize to a custom size?+

Yes. Enter any width and height in pixels. Common presets are also provided.
