Sometimes you need a page of a PDF as a picture: for a slide, a social post or a document thumbnail. Open a PDF, tick the pages you want or type a range like 1-3,5, choose the resolution and format, and every page is rendered to an image right on your computer.

Overview
Rendering a PDF page means interpreting its drawing commands, including text with embedded fonts, vector shapes and placed images, and painting them onto a pixel grid. This tool uses PDF.js, the open-source renderer built into Firefox, which is loaded on demand and runs in a web worker in your tab. As soon as the file opens you get a thumbnail of every page, rendered one after another, so even long documents become browsable within seconds.
The most important setting is resolution, expressed in DPI (dots per inch). PDF pages are measured in points at 72 per inch, so 72 DPI gives one pixel per point: an A4 page becomes 595 × 842 pixels, fine for thumbnails but too small for most uses. At 150 DPI the same page is about 1240 × 1754 pixels, good for slides and reading on screen. At 300 DPI it is about 2480 × 3508 pixels, suitable for print, OCR and zooming into small text. Doubling the DPI quadruples the pixel count and memory, so the tool shows the resulting size of page 1 before you start, and very large pages are scaled down just enough to stay within browser canvas limits.
PNG is the best output for pages of text, line art and charts because it keeps edges crisp with no compression artifacts. JPG suits pages that are mostly photographs and produces much smaller files; WebP is smaller still and supported by every modern browser. Pages normally render on white, as they look in a viewer, but for PNG and WebP you can switch on a transparent background, which is handy for logos or diagrams exported from design tools.
Pages are rendered one at a time with a progress bar and a Cancel button, so a 200-page export never locks up the browser and you can stop at any point and keep what’s finished. Each image is named after the PDF and page number, for example report-page-03.png, and can be saved individually or as one ZIP. Password-protected PDFs prompt for the password, which is used only inside the tab to decrypt the file.
| DPI | A4 pixels | US Letter pixels | Typical use |
|---|---|---|---|
| 72 | 595 × 842 | 612 × 792 | Thumbnails and previews |
| 150 | 1240 × 1754 | 1275 × 1650 | Slides, web, on-screen reading |
| 300 | 2480 × 3508 | 2550 × 3300 | Print, OCR, zooming into detail |
Drop a PDF onto the page or browse to open it.
Enter the password if the PDF is protected.
Click thumbnails to choose pages, or type a range such as 1-3,5 or 4- in the Page range box.
Pick 72, 150 or 300 DPI and PNG, JPG or WebP, plus a quality for JPG or WebP.
Click Convert, watch the progress bar, then download single pages or Download all (ZIP).
Use cases
Drop a chart or page from a report into PowerPoint, Keynote or Google Slides as a clean 150 DPI image instead of a fuzzy screenshot.
Turn a one-page flyer, menu or infographic PDF into a PNG or JPG you can post on Instagram, LinkedIn or X, which don’t accept PDF uploads.
Render the first page at 72 DPI as a JPG or WebP to use as a cover image next to a download link, course library entry or file listing.
Export just the signature page or one diagram at 300 DPI for an OCR app or a colleague, without sending the whole document.
Pro tips
Answers to common questions about the pdf to images.
150 DPI suits most screen uses such as slides and web pages. Choose 300 DPI for printing, OCR or when readers need to zoom into small text. 72 DPI is only useful for small thumbnails and previews.
Yes. Text is drawn from the fonts embedded in the PDF at the chosen resolution, so it is crisp at 150 and 300 DPI. Exporting as PNG also avoids JPG compression artifacts around letters.
Yes, if you know the password. The tool asks for it when the file opens and uses it only inside your browser tab to decrypt the pages. Without the password the pages can’t be rendered.
Browsers cap the size of a single canvas. Very large pages, such as posters or engineering drawings at 300 DPI, are scaled down just enough to stay under about 50 megapixels and 16,384 pixels per side.
This tool renders whole pages as they appear. Extracting embedded photos as their original files is a different process; rendering at 300 DPI and cropping is a practical alternative.
Yes. A scanned PDF is a set of images on pages, and each page renders like any other. Use 300 DPI if you plan to run the images through OCR.
No. ToolEnhancer processes files on your own device inside the browser. They are never sent to, stored on or seen by our servers.
