How to resize an image in pixels
1. Choose Add files and select your images. Check the original dimensions, then choose Original to keep the shape, a preset ratio, or Custom for another ratio.
2. For a new ratio, choose Crop to fill the frame or Pad to keep the whole picture with a white margin. With Crop, drag the frame on the original preview to keep the part you need.
3. Enter the Long edge in pixels and check Expected size. For example, a 4:5 ratio with a 1350px long edge gives 1080×1350px when the original is large enough. This tool reduces images without enlarging their content.
4. Choose Run Resize, compare the original and result, then download the completed files or Batch ZIP. Check the saved image dimensions. If an upload also has a file-size limit, compress the resized file afterward and check its actual bytes.
How do I resize a photo to 1080×1350 pixels?
Choose the 4:5 ratio and enter 1350 for Long edge. Check Expected size before running. The source must be large enough for the chosen crop; this resizer does not enlarge image content. Check the downloaded dimensions too.
What does Long edge mean?
It is the larger of the output width and height, measured in pixels. With Original selected, a 1600×900 image reduced to an 800px long edge becomes 800×450. The Custom width and height fields set a ratio, not independent pixel dimensions.
Should I choose Crop or Pad?
Crop fills the selected shape and removes content outside it; move the crop frame to protect the subject. Pad keeps the whole picture inside the shape and adds a white margin where needed. Choose Original if you want to keep the existing ratio.
Why does the Long edge value become smaller?
The tool limits resizing to avoid enlarging the original content. A crop or a batch containing smaller images can lower the available range. Check Expected size and the completed result. Use the separate Upscale tool when enlargement is your task.
Will resizing make my image fit a KB or MB limit?
Fewer pixels can reduce file size, but a pixel setting does not guarantee a byte limit. Resize to the dimensions you need, then use Compress if the file is still too large. Check the downloaded file's actual size and the upload site's accepted format.
