Remove unwanted edges or isolate a consistent region from static WebP images with an explicit percentage rectangle that can also be applied across a batch.
How to use Crop WebP
- Choose static WebP images.
- Set the left and top starting position, then the retained width and height percentages.
- Crop locally, confirm the reported pixel dimensions, and download the results.
What this tool is good at
When to use Crop WebP
Subject reframing
Remove unwanted edges and create a tighter composition for cards, banners, avatars, or product tiles.
Aspect-ratio preparation
Crop a source toward the layout's required proportions before resizing it to final dimensions.
Privacy trimming
Exclude visible surroundings or incidental information from an image without sending it to a cloud editor.
How to choose the right settings
Coordinates are percentages
Percentage controls keep the crop understandable across different source dimensions and calculate exact output pixels at processing time.
Keep the crop inside bounds
Width plus horizontal offset, and height plus vertical offset, must remain within the source canvas.
Crop before resizing
Removing unwanted pixels first avoids spending output dimensions and file size on content that will not be used.
Practical workflow and output details
The selected source rectangle is drawn into a new canvas at its native cropped dimensions and encoded as a static WebP.
Transparency can survive the pixel operation, but animation and metadata do not. Cropping cannot recover detail outside the selected source area after download.
Format behavior and limitations
The crop rectangle is rounded to whole source pixels and clamped within image bounds.
Output is re-encoded as WebP, so animation and embedded metadata are not preserved.
Frequently asked questions
Why are crop values percentages?
Percentages let one crop recipe work consistently across a batch even when source images have different pixel dimensions.
What if width extends beyond the image?
The processor clamps width and height to the remaining area after the selected left and top offsets.
Does cropping retain transparency?
Yes. Transparent pixels inside the retained rectangle remain transparent in the new WebP.
