A4 print cover resizing
This tool automatically applies a center-weighted crop to fit your graphics into a 2480×3508 pixel canvas. This dimension perfectly matches an A4 portrait page layout at 300 DPI for high-quality printing.
When you import a file, the resizer proportionally scales it to fill the entire 2480×3508 frame. Any horizontal overflow is cropped off, ensuring your content neatly fills the A4 aspect ratio without stretching.
Batch poster resizing
You can resize multiple document scans or posters to the 2480×3508 format simultaneously. A local worker pool handles the heavy canvas resize image operations directly on your hardware.
Drop a collection of JPEG, PNG, or WebP files into the queue. After processing completes, you can review each 2480×3508 page output or download the full batch as a ZIP archive.
Local document processing
All pixel calculations and rendering are executed entirely within your browser. Your printable documents and personal assets are never sent to external servers.
Because the tool uses your device to resize image canvas files, importing high-resolution artwork or scans guarantees sharp A4 prints instantly.
