About Image Resizer
Resize an image online to exact width and height values for websites, profiles, documents, email, social media and other upload requirements.
Image resizing changes an image's pixel dimensions. Keeping the aspect ratio locked helps avoid distortion, while resizing a large source before compression can make the final file easier to upload and share. Image dimensions, file format, transparency, source quality and compression settings affect the output. Compare the output dimensions, visual quality, transparency and file size with the original image.
Primary objective: Changes an image to the dimensions required by a website, profile, document or other destination.
Privacy assurance: Image decoding and processing are performed in the browser from the file you select.
