Trim the edges of every page by percentage to remove unwanted margins.
100% local — files never leave your deviceProcessed in your browser
How it works
Upload a PDF.
Set how much to trim from top/right/bottom/left.
Crop and download — content stays centered within the new margins.
Good to know
Cropping adjusts page geometry; nothing outside the crop box is deleted from the file. Use Flatten→rasterize or Metadata→clean for stricter sharing situations.
Every step runs locally in your browser using Web Workers — your file is never uploaded to any server.
