Turn any PDF page into a sharp PNG image — right in your browser
Drop in a PDF and get back a PNG image for every page, ready to share, embed, or edit. No account, no upload, no waiting — the whole conversion happens locally in your browser.
This is handy when you need to paste a diagram from a PDF into a slide deck, send a single-page preview as an image, or extract a chart without firing up Acrobat.
How to convert PDF to PNG
- Open the tool above and click Choose File (or drag your PDF straight onto the drop zone).
- Pick the pages you want. Leave it on All pages to export everything, or enter a range like
1-3to grab only those slides. - Click Convert. The tool renders each page and packages the PNGs for download.
- Download your images. You'll get one PNG per page, named by page number so they stay in order.
Your PDF never leaves your device. All rendering is done with JavaScript running locally — no file is ever uploaded to a server. That matters when the PDF contains contracts, medical records, or anything sensitive.
Worked example: extracting a cover page
Say you have a 12-page product brochure called brochure.pdf and you only need the cover as a social-media graphic.
- Input:
brochure.pdf— 12 pages, A4 size, 2 MB - Page range:
1 - Output:
brochure_page_1.png— 1240 × 1754 px, transparent-friendly, ready to drop into Canva or Photoshop
The resulting PNG is a raster image (made of pixels) that keeps text crisp and colours accurate, even at high zoom. If you later need the vector source back, you still have the original PDF — PNGs are a one-way export.
How to do this in Python or JavaScript
If you need to automate the conversion in your own project, here are two minimal, runnable examples.
Python (using pdf2image)
# pip install pdf2image
# also requires poppler: https://poppler.freedesktop.org/
from pdf2image import convert_from_path
pages = convert_from_path('brochure.pdf', dpi=150, first_page=1, last_page=1)
pages[0].save('cover.png', 'PNG')
dpi=150 gives a good screen-quality image; use 300 for print. pdf2image wraps Poppler's pdftoppm utility under the hood.
JavaScript (Node.js, using pdf-to-img)
// npm install pdf-to-img
import { pdf } from 'pdf-to-img';
const doc = await pdf('brochure.pdf', { scale: 2 });
for await (const page of doc) {
// page is a Buffer containing PNG data
require('fs').writeFileSync(`page_${doc.currentPage}.png`, page);
}
scale: 2 doubles the default resolution for sharper output. This library uses PDF.js internally — the same engine that powers Firefox's built-in PDF viewer.
How it works under the hood
The converter uses PDF.js — Mozilla's open-source, JavaScript-native PDF rendering engine — to parse the file and paint each page onto an HTML <canvas> element. That canvas is then exported as a PNG using the browser's built-in canvas.toBlob() API.
Because PDF.js is a pure JavaScript library, it runs entirely client-side. There is no server component involved, which is what makes the privacy guarantee real rather than just a marketing claim. You can read more about PDF.js on Mozilla's official PDF.js project page.
PNGs use lossless compression, meaning every pixel is stored exactly as rendered — unlike JPEG, which trades some sharpness for a smaller file. This makes PNG the right choice for text-heavy pages, diagrams, and anything with a transparent background.
When to use PDF-to-PNG conversion (and when not to)
| Use it when… | Skip it when… |
|---|---|
| You need a quick screenshot of one or two pages | You need the text to remain selectable (use the PDF directly) |
| Embedding a PDF page in a blog post, email, or social graphic | The recipient needs to search or copy-paste the text |
| Sharing a preview without giving access to the full document | You need a smaller file — PNG of a complex page can be large |
| Running OCR on a scanned document (many OCR tools prefer images) | You need vector graphics — export to SVG instead |
| Archiving a visual snapshot of a report | You want to edit the content later — keep the original PDF |
One more thing: if you need to go the other direction and build a PDF from a set of images, this same tool handles that too — just switch to the image-to-PDF mode above.
