What is an Image Resizer?

An image resizer is a free browser utility that changes the pixel width and height of JPG, PNG, and WEBP images for blogs, stores, social media, and thumbnail requirements.

How to Use

Select a JPG, PNG, or WEBP image.
Choose a reduction preset or enter custom width and height values.
Review the output format, quality, and transparency settings.
Apply the size, review the result information, and download the file.

Blog Content

A width of about 800–1200 px is common depending on the content area. Avoid images that are much larger than their actual display size.

Thumbnails

Reducing card or list thumbnails to about 300–800 px based on your service requirements can improve loading speed.

Social Media

Recommended sizes vary by post type. Check the platform requirements and keep the ratio locked to prevent distortion.

Can I enlarge an image beyond its original size?

You can, but enlarging cannot create missing detail, so the result may look blurry or pixelated. Enlargement prevention is enabled by default.

Why should I lock the aspect ratio?

Keeping the width-to-height ratio prevents the image from looking stretched. Unlock it only when you must match an exact custom size.

Is my uploaded image stored on the server?

No. Reading, resizing, previewing, and generating the download file all happen inside your current browser.
