How to use PDF to images
- Choose the PDF.
- Pick a resolution: 72 dpi for screens, 150 for general use, 300 for print.
- Pick PNG for sharp text or JPG for smaller files, and all pages or only some.
- Select Convert to images and download the zip.
Resolution and format
Resolution sets how many pixels each inch of the page becomes. At 150 dpi an A4 page becomes an image of about 1,240 by 1,754 pixels, enough for documents, slides and social posts. At 300 dpi it is about 2,480 by 3,508, for printing or zooming into fine detail; at 72 dpi it is a small preview.
PNG keeps text and line drawings perfectly sharp and suits documents. JPG makes much smaller files and suits pages that are mostly photographs. Transparent areas are painted white, so nothing turns black in a JPG.
How the pages are drawn
Pages are rendered by pdf.js, the open-source PDF engine used by Firefox, running in this browser tab. Its worker, standard fonts and character maps for Chinese, Japanese and Korean text are served from this site, so rendering does not depend on a third-party server. Embedded fonts are used as they are, and fonts are never compiled with eval.
Each image is named after your file and its page number, zero-padded so they sort in page order, and all of them arrive in one zip. You can convert only some pages by typing them, for example 1, 4-6.
What happens to your file
The PDF never leaves your device. It is read into memory in this tab, drawn page by page, and the images are packed into the zip there too. Very large documents at 300 dpi use a lot of memory; convert them in smaller page ranges if your browser struggles.
Common uses
Posting a page of a report or a slide on social media, putting a page into a document editor that does not accept PDFs, making thumbnails for a website, or sending one page as a picture that opens on any phone. Each image shows the whole page, exactly as a PDF viewer would display it at that resolution, including text, drawings and any photos on it.
Questions
- What resolution should I choose?
- 150 dpi suits slides, documents and sharing. Use 300 dpi for printing or for zooming into detail, and 72 dpi for small previews. Higher resolutions take longer and make bigger files.
- Is my PDF uploaded?
- No. Pages are drawn by pdf.js, an open-source PDF renderer, running in your browser tab. pdf.js and its fonts load from this site, not from a third party.
- Are fonts rendered correctly?
- Yes. Embedded fonts are used as they are, and the standard PDF fonts and character maps for Chinese, Japanese and Korean text are included.
