High-Precision PDF Trimming for Professional Use
A PDF editing tool born from real-world design experience, built to meet professional needs. More than simple cropping -- it combines mm-precision coordinate input and batch conversion to support professional workflows.
Secure Local Processing Without Servers
All processing takes place entirely within your browser -- a fully local design. Files are never uploaded to or stored on external servers for trimming or other operations. (Note: Please use this tool at your own discretion.)
Trim Marks Removal and Data Formatting
Quickly remove print trim marks (bleed marks) from design files and reformat them for client review or digital distribution. Precisely cut only the visible area while preserving vector data and image quality.
Remove Margins and Black Borders from Scanned Data
Cut uneven margins from digitized books or scanned documents. By removing excess space, you can maximize readability when viewing on tablets or other devices.
Fast Batch Processing for Large Volumes
Drop multiple PDFs at once and apply the same crop area to all of them. Results are automatically saved as a ZIP file, completing tedious routine work in seconds.
Frequently Asked Questions (FAQ)
Does cropping reduce image quality?
No, there is no quality loss. This tool modifies the internal PDF data (CropBox) rather than recompressing images, so text and vector graphics remain crisp.
Can I use this on smartphones or tablets?
Yes, it works on any device with a modern browser (Safari, Chrome, etc.). Since it runs entirely in the browser, no additional apps need to be installed.
Are there usage limits or fees?
All features are completely free to use. There are no file or page limits, and no ad interruptions. Use it for anything from business to personal projects.
