How it works
Resize a sequential local image batch using a containing box or center crop, explicit enlargement policy and selected output format. Each result has a separate download.
Read the source reference ↗A few things to know
Fit can produce different output dimensions. Center crop removes edges. Limits: 25 MB total, 20 images, 16 million pixels per source and output, and 8,192 pixels per side. Files are flattened, metadata is not copied and animations become one frame. JPEG uses a white background for transparency.
When to use this tool
Resize a product-image batch deliberately. Fit preserves the complete image; center crop fills the chosen dimensions by removing edges.
- Resize product images.
- Prepare thumbnail files.
- Normalize image bounds.

Frequently asked questions
Definitions, edge cases, and practical next steps for this tool. Search all tool FAQs ↗
Does Fit stretch images?
No. It preserves the original ratio inside the target box.
Does Center crop preserve everything?
No. It removes edges to fill the exact output box.
Can I enlarge images?
Only when you explicitly allow it; enlargement cannot create original detail.
Are all images downloaded in a ZIP?
No. Each image has a separate numbered download.
What does the preview show?
The first processed image; inspect the other downloaded results too.
Are metadata and animation preserved?
No. Canvas export produces a flattened single frame without copying metadata.
Are my inputs uploaded or stored?
Processing happens locally in your browser. This tool does not upload inputs. Downloads stay on your device; sharing or opening them in another service is your choice.
What should I check before using the output?
Fit can produce different output dimensions. Center crop removes edges. Limits: 25 MB total, 20 images, 16 million pixels per source and output, and 8,192 pixels per side. Files are flattened, metadata is not copied and animations become one frame. JPEG uses a white background for transparency.
