Frequently asked questions
Are my images uploaded anywhere?
No. ResizeWizard does all the work in your browser using the canvas API, so your photos never leave your device.
How do I resize an image to an exact file size?
Open a 'resize to KB' preset, drop in your image, and the tool compresses it to fit just under the target size automatically.
Which formats can I work with?
You can import JPG, PNG, WebP, GIF, and AVIF, and export to JPG, PNG, or WebP depending on what you need.
Will resizing reduce my image quality?
Resizing to similar dimensions keeps images sharp. For strict file-size limits, JPG or WebP give the best balance of size and clarity.
