How to do it

  1. Choose a photo.
  2. Type the width and height, e.g. 1200 × 628. Leave one blank to keep the ratio.
  3. Pick crop to fill, fit with a border, or stretch.
  4. Download as JPG, PNG or WebP.

Crop, fit or stretch?

When the new size has a different shape from your photo, something has to give. Pick a photo shape and a target shape to compare the three options.

The frame it must fill
3:2 photo → 4:5 frame: 47% of the photo is cut off. The faded area is what a platform trims when it "fills" the frame, which is why picking the crop yourself matters.

Questions

How do I resize without losing quality?

Making an image smaller keeps it sharp. Making it bigger than the original can only invent pixels, so it looks soft; CropMaster warns you when that would happen.

How do I reduce the file size?

Resize to the size you actually need, choose JPG or WebP, and lower quality to 75–85. That usually shrinks files by 80–95% with little visible change.

What does “keep aspect ratio” mean?

Width and height change by the same factor so nothing looks stretched. Leave one box blank here and it is calculated for you.
