Trim First: Cropping Before Shrinking an Image

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points

Cropping unneeded parts lightens it without losing quality
Then shrink with "Compress & Resize Images"
Keep the original

Image file size grows with the number of pixels. Reducing the area shown lightens it without losing quality.

Steps

In "Crop & Rotate Image", crop to just the part you need and save.
In "Compress & Resize Images", choose the cropped image.
Choose size and quality, and compress.

When it helps

When a document photo has a lot of desk or background around it
When you only need part of a landscape

Notes

Cropping can't be undone later, so keep the original.
Compressing before cropping can degrade quality twice. The order is "crop → compress".

Use "Crop & Rotate Image" (free)
