How do I resize an image for Instagram or YouTube?

Add your photo, pick a Platform size such as Instagram Story 1080 x 1920 or YouTube Thumbnail 1280 x 720, choose Cover, Fit or Stretch, then download the current size.

Can I get every platform size at once?

Yes. The download-all button builds a ZIP containing every preset size from your one image, in the Format you selected: PNG, JPG or WebP.

How do I choose which part of the photo gets cropped?

With Cover, the image fills the frame and the edges are cropped. Drag the preview to reposition the crop, and double-click to recenter it.

Can I use a custom size, and is there a limit?

Yes, choose the custom preset and enter Width and Height in pixels. Each must be between 16 and 8192 px; outside that range the tool shows an error.

Is my image uploaded when I resize it?

No. Resizing happens in your browser with the Canvas API, so the image stays on your device. Banner presets also show a Safe-zone guide so important content is not cut off.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Are my files uploaded?

No. Your files are opened and processed inside your browser and are not sent to LibraTool. Some tools first download a processing engine or AI model to your browser; that download contains no data of yours.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install. Very large files can be slow or run out of memory on a phone, so use a computer for those.
