How to Convert to PNG

1
Add your PDF
Drop in one file or up to twenty. Every document is opened by your own browser, so nothing is uploaded and nothing sits in a queue waiting for a server.
2
Set DPI and transparency
Choose a resolution from 72 to 600 DPI, decide whether empty areas stay transparent, and turn on optimisation if you want smaller files.
3
Download the PNG files
A single page comes back as one .png. Several pages arrive as a ZIP archive with each image numbered in page order.

Lossless pixels, and when that matters

PNG stores every pixel as it was drawn, so thin lines, small type, screenshots, diagrams and flat colour survive without the soft haloes that JPEG leaves around sharp edges. The cost is size: the same A4 page at 150 DPI is usually 350 to 900 KB as PNG against 120 to 250 KB as JPEG. Choose PNG for anything with text or line art that will be zoomed, re-cropped or placed into another document, and JPEG for photographic scans where a few percent of quality is invisible anyway.

Transparent backgrounds and optimisation

With transparency on, nothing is painted behind the page: wherever the PDF draws nothing, the alpha channel stays empty, which is what you want when lifting a logo, stamp or signature onto another document. Many PDFs draw a solid white rectangle first, and those pages will come out white anyway. Optimisation runs the finished image through oxipng, which rewrites the compression without touching a single pixel and typically saves 8 to 22 percent on pages full of text.

The document never leaves your computer

Pages are rendered inside your browser tab by its own engine, in a background thread. The PDF is not uploaded, not queued and not stored anywhere for us to delete afterwards, so confidential drawings, contracts and scans stay on your machine. Close the tab and everything held in memory disappears with it.

Frequently asked questions

Should I convert a PDF page to PNG or JPG?

Choose PNG when the page holds text, tables, diagrams or line art, because nothing is blurred and edges stay crisp. Choose JPG for photographic scans and for anything you need to keep small, since a JPEG page is usually three to five times lighter.

Why is my transparent PNG still white?

Because the page itself paints a white rectangle before anything else, which most exported PDFs do. Transparency only leaves alpha where the document draws nothing at all, so it works best on logos, stamps and signatures placed on an otherwise empty page.

Which DPI do I need for printing?

Use 300 DPI for print, which is the usual standard for documents and photographs. For screens, 150 DPI is enough, and 72 or 96 DPI is fine for previews. Above 300 DPI files grow fast without looking any better on a monitor.

How is this different from extracting images from a PDF?

This draws the whole page, text and vector graphics included, into one flat picture. Extracting images returns only the photos somebody embedded in the file, at the size they were stored, and leaves out everything drawn around them.

Why is a PNG heavier than a JPG of the same page?

Because PNG compression is lossless: it must keep every pixel intact, while JPEG throws away detail the eye rarely notices. That is why PNG is the right choice for sharp text and the wrong one for a large photographic scan you plan to email.

What does the optimisation option do?

It re-compresses each finished PNG with oxipng, which searches for a better encoding of the same pixels. The image is bit-for-bit identical after decoding, files usually shrink by 8 to 22 percent, and each page takes about half a second to a second longer.

Does my file get uploaded to a server?

No. Rendering happens in your own browser on your own machine, so no page ever crosses the network. Once this page has loaded you can even disconnect, convert the document offline, and still get your images.
