Usage

Converting specific page of PDF from path, then saving as image file

import { fromPath } from "pdf2pic";

const options = {
  density: 100,
  savename: "untitled",
  savedir: "./images",
  format: "png",
  width: 600,
  height: 600
};
const storeAsImage = fromPath("/path/to/pdf/sample.pdf", options);
const pageToConvertAsImage = 1;

storeAsImage(pageToConvertAsImage).then((resolve) => {
  console.log("Page 1 is now converted as image");

  return resolve;
});

Converting specific page of PDF from path, then saving as base64 string of image

import { fromPath } from "pdf2pic";

const options = {
  density: 100,
  savename: "untitled",
  savedir: "./images",
  format: "png",
  size: "600x600"
};
const convertPdf2Base64Image = fromPath("/path/to/pdf/sample.pdf", options);
const pageToConvertAsImage = 1;

// adding true as second parameter will transform response to base64 string
convertPdf2Base64Image(pageToConvertAsImage, true).then((resolve) => {
  console.log("Page 1 is now converted as base64string");

  console.log({
    base64string: resolve.base64
  })

  return resolve;
});

Bulk conversion

import { fromPath } from "pdf2pic";

const options = {
  density: 100,
  savename: "untitled",
  savedir: "./images",
  format: "png",
  size: "600x600"
};
const convert = fromPath("/path/to/pdf/sample.pdf", options);
const pageToConvertAsImage = [4, 5]; // let's convert page 4 and 5

convert.bulk(pageToConvertAsImage).then((resolve) => {
  console.log("Page 4 and 5 is now converted as image");

  return resolve;
});

PDF Stream input, saved as image file

import { fromBuffer } from "pdf2pic";
import { readFileSync } from "fs";

const options = {
  density: 100,
  savename: "untitled",
  savedir: "./images",
  format: "png",
  size: "600x600"
};

const file = readFileSync("/path/to/pdf/sample.pdf", "base64");
const buff = Buffer.from(file, "base64");

const convert = fromBuffer(buff, options);
const pageToConvertAsImage = 1;

convert(pageToConvertAsImage).then((resolve) => {
  console.log("Page 1 is now converted as image");

  return resolve;
});

PDF base64 input, saved as image file

import { fromBase64 } from "pdf2pic";
import { readFileSync } from "fs";

const options = {
  density: 100,
  savename: "untitled",
  savedir: "./images",
  format: "png",
  size: "600x600"
};

const file = readFileSync("/path/to/pdf/sample.pdf", "base64");

const convert = fromBase64(file, options);
const pageToConvertAsImage = 1;

convert(pageToConvertAsImage).then((resolve) => {
  console.log("Page 1 is now converted as image");

  return resolve;
});
