Why this matters
Image resizing changes the dimensions of an image, such as width and height in pixels. Resizing is useful for profile photos, website images, forms and email attachments.
Practical example
Keeping aspect ratio prevents images from looking stretched or distorted. Reducing dimensions can also reduce file size significantly.
Best practices
For best results, resize from a high-quality original image. After resizing, preview the output before uploading it to important forms or websites. Use online tools carefully and always verify important results before submitting files, financial values or production code.
