Crop before or after upscaling? Plan by pixels
Use a pixel budget to plan your crop instead of assuming that upscaling first always looks sharper.
Cropping changes the frame, not automatically the retained detail
Cropping removes edge pixels and reduces the total count. Without resampling, each retained pixel remains the same. Decide the final ratio, subject position and required detail before choosing an order.
Crop first when the composition is fixed
If you only need a small subject area, crop externally and then calculate the required dimensions. This allocates the requested size to that area but removes context. It does not guarantee a more accurate AI result. Keep the uncropped original.
Keep the full frame for multiple layouts
A full image is more flexible when you need a banner, square and portrait version. If you upscale first, check the remaining pixels of every crop. A 4K-labelled full image does not make every crop 4K.
Work through the pixel budget
An actual 3840 × 2160 image becomes 2160 × 2160 when cropped to a centered square. At 300 PPI that is about 18.3 × 18.3 cm. This is geometry, not a guaranteed output. Images are processed individually; testing both orders creates separate charges for successful jobs.
| Situation | Suggested action | What to check |
|---|---|---|
| Fixed composition | Crop a copy, then assess upscaling | Enough information in the retained area |
| Multiple layouts | Keep the full frame and budget each crop | Actual pixels in every version |
| Tiny subject | Find a closer original first | Do not expect identity details to be recovered |
Cropping is not automatic in this tool. Use an external editor for crops and exact layouts.
