PDF to Image
At 150 dpi an A4 page becomes 1240 x 1754 pixels, and at 300 dpi 2479 x 3508 pixels. Pick PNG for text or JPG for photos. Files up to 50 MB and nothing is uploaded.
How to use
- Drop a PDF onto the box, or press it to choose a file (up to 50 MB). The page count is shown.
- Leave Pages empty to convert every page, or type a range such as 1-3,5. Choose PNG or JPG and a resolution: 72 dpi for screens, 150 dpi for everyday use, 300 dpi for printing.
- Press Convert to images. Each page appears in the list with its pixel size and file size. Download them one by one, or take all of them as a ZIP.
How it works
A PDF page is measured in points, and one point is 1/72 inch. The image width in pixels is the page width in points times dpi divided by 72, so an A4 page (595 x 842 points) at 150 dpi becomes 1240 x 1754 pixels and at 300 dpi 2479 x 3508 pixels.
PNG keeps every pixel exactly and suits text and line art. JPG makes smaller files for photos, and transparent areas are filled with white. Very large pages are scaled down to fit the limit of this browser, and the tool tells you when that happens.
Pages are drawn with pdf.js in your browser, and the font and decoder files come from this site. Your document is never sent to a server.
FAQ
Is my PDF uploaded?
No. The file is read and drawn in this browser tab. There is no upload, no account and no copy kept anywhere else.
Which resolution should I pick?
72 dpi is enough for a quick preview, 150 dpi is sharp on screens and fine for most sharing, and 300 dpi is for printing. Higher resolution makes larger files and takes longer.
PNG or JPG?
Use PNG for text, tables and diagrams because it stays crisp. Use JPG for pages that are mostly photos, because the files are much smaller.
Why is there a page limit per run?
Each image is kept in memory until you download it, so one run is limited to 300 pages. Use the Pages box to convert a long document in parts.
Why does it say the file is password protected?
The PDF is encrypted, so it cannot be opened without its password. Open it in a PDF viewer, remove the password (save or print to a new PDF), then add that copy here.
