Image Resizing FAQs

How do I resize an image online for free?

Upload your photo to our tool, enter your desired target width and height in pixels (or pick a preset), choose whether to lock aspect ratio, select your format (JPG, PNG, WebP), and click 'Resize Image'. Download the resized image instantly.

Does resizing an image reduce its file size?

Yes, in most cases downscaling image dimensions reduces the total pixel count, which lowers file size significantly. You can also adjust the quality slider to reduce the file size further.

Can I resize an image without distorting it?

Yes. Keep 'Lock Aspect Ratio' enabled so changing width automatically calculates the proportionate height. Alternatively, use 'Crop & Fill' mode to fill exact target dimensions while centering the subject.

Is my image uploaded to your server?

No. All resizing runs entirely in your web browser using client-side HTML5 Canvas. Your images are never transmitted over the internet or saved to any database.
