Resize Image

Resize Images Without Installing Software

Upload JPG, PNG, WebP or AVIF images, set the new dimensions and download resized files. This is useful for website images, profile photos, product photos, blog graphics, thumbnails and upload forms that require a specific size.

Width, Height and Aspect Ratio

You can enter only a width, only a height or both values. When one side is left blank, PDFem keeps the original proportions. For fixed layouts, choose an aspect ratio preset such as square, 16:9, 9:16 or 4:3. Use Custom when a form or platform gives you exact dimensions.

Fit Modes

Fit inside keeps the full image visible inside the size you choose. Crop to fit fills the target size and trims the edges if needed. Add padding keeps the whole image and fills the empty space around it. Stretch forces the exact width and height, which can distort the picture but is sometimes required by strict upload forms.

Batch Resizing

Resize up to 30 images with the same settings. That saves time when preparing product galleries, social posts, screenshots or web assets. If you resize more than one file, the results are packaged into a ZIP download.

Output Format

You can keep the original format or export resized files as JPG, PNG, WebP or AVIF. Use JPG for photos, PNG for transparent graphics, WebP for most website images and AVIF when smaller modern web files are the priority.
