File
File Manipulation
Trelae lets you transform uploaded files by queuing one or more operations—such as resizing, cropping, tinting, adding text—and then applying them all at once with .save().
Currently, only image files (image/*) are supported for manipulation. Support for PDFs and additional file types is coming soon.
Supported Operations (current image support)
- resize / crop
- compress / convert / rotate / flip
- border / background
- grayscale, blur, sharpen, tint, adjust
- threshold, trim
- composite (overlay another file/image)
- addText
- removeBackground
How It Works
- Create a file handle:
const file = trelae.file('FILE_ID') - Chain operations:
file.resize({ width: 400 }).rotate(90)... - Apply everything with
.save()
