The Crop PDF Python library lets you precisely trim PDF pages. Choose automatic content detection with optional padding, crop by exact width/height anchored to a page corner or center, or crop by setting horizontal/vertical margins. Combine with page ranges and measurement units (points, inches, millimeters, centimeters).

Values: custom a2 a3 a4 a5 a6 letter legalPageOrientation
Collection Default: defaultSet page orientation.
Values: default portrait landscapeCropWidth
DoubleWidth of the crop box, expressed in the selected measurement unit. Takes effect when CropMode is set to Size. When set, it overrides PageSize for the horizontal axis, leave it empty to crop the width to the selected PageSize.
CropHeight
DoubleHeight of the crop box, expressed in the selected measurement unit. Takes effect when CropMode is set to Size. When set, it overrides PageSize for the vertical axis, leave it empty to crop the height to the selected PageSize.
VerticalMargin
Double Default: 1Top and bottom margins to apply when defining the crop box, using the selected measurement unit. Takes effect when CropMode is set to Margins.
HorizontalMargin
Double Default: 1Left and right margins to apply when defining the crop box, using the selected measurement unit. Takes effect when CropMode is set to Margins.
StoreFile
Bool Default: FalseWhen the StoreFile parameter is set to True, your converted file is written to ConvertAPI’s encrypted, temporary storage and made available via a time-limited secure download URL, valid for up to 3 hours. After this period, the file is permanently deleted.
When StoreFile is set to False, conversion happens entirely in-memory. The raw file bytes are streamed back in the API response without touching disk or external storage, ensuring maximum security and zero persistence so that only you can access the content.
