Question 1

Does cropping affect PPM quality?

Accepted Answer

No. Cropping removes pixels outside the crop area without resampling. Quality is preserved.

Question 2

Can I compress while cropping?

Accepted Answer

Yes. Under "Image Compression," choose any method. Since PPM is uncompressed, even moderate compression dramatically reduces file size.

Question 3

Can I also resize while cropping?

Accepted Answer

Yes. Under "Image resolution," set by percentage or keep original.

Question 4

Should I crop as PPM or convert to PNG?

Accepted Answer

For continued use in processing pipelines, keep PPM. For general use, PPM to PNG gives lossless compression at much smaller file sizes.

Question 5

Can I enter exact crop dimensions?

Accepted Answer

Yes. Enter exact pixel coordinates for the crop area, or drag the crop box visually.
