A free Image Resizer for changing image dimensions for websites, documents, social posts, profiles and other digital layouts.
About Image Resizing
Image resizing changes the pixel dimensions of a picture. It is useful when a website, application, document or social platform requires a specific width or height. Tervilo can resize common raster formats in the browser and can preserve the aspect ratio to avoid accidental stretching.
How to use this tool
- Choose an image.
- Enter the target width or height in pixels.
- Keep Maintain aspect ratio enabled when you want proportional resizing.
- Choose an output format if required, then process and download the result.
Important notes
Increasing dimensions cannot recreate detail that was not present in the original image. For sharp results, start with the highest-quality source available.
Privacy and browser processing
For these image operations, Tervilo is designed to process the selected image data in your browser. The page does not need to upload the image to a Tervilo application server for the normal conversion workflow. You should still keep your original file until you have checked the downloaded result.
