How to use the PDF to Images tool
- Choose your PDF. The page count appears once it has been read.
- Select PNG for sharp text and graphics or JPG for smaller files, then pick a resolution from 72 to 300 DPI.
- Optionally enter pages such as 1-3, 8 to convert only part of the document.
- Press Convert to images, watch the progress bar, then download each image or all of them as a ZIP.
Worked example: three pages of a 12-page Letter document
slides.pdf has 12 US Letter pages, each 612 x 792 points (8.5 x 11 inches). You choose PNG, 150 DPI and type 1-3 in the Pages box.
- Each page is drawn at 150 / 72 = 2.083 pixels per point, giving images of 1,275 x 1,650 pixels.
- The files are named slides_page-01.png, slides_page-02.png and slides_page-03.png. The number is padded to two digits because the document has 12 pages, so the files sort correctly.
- At 300 DPI the same pages would be 2,550 x 3,300 pixels; at 72 DPI they would be 612 x 792 pixels.
Choosing format and resolution
PNG is lossless and keeps text edges perfectly sharp, so it suits documents, slides and screenshots, but files can be several megabytes per page. JPG is much smaller and fine for photos and scans, with a quality slider to trade size for detail. Resolution decides how many pixels each page gets: 72 DPI is screen-sized, 150 DPI is a good all-round choice for reading and sharing, and 300 DPI is for print. An A4 page at 150 DPI is about 1240 by 1753 pixels; at 300 DPI the pixel count quadruples.
Big documents
Pages are drawn one after another with a progress bar, and you can press Stop to end early; the pages finished so far remain available. At 300 DPI a long document can create hundreds of megabytes of images in your browser memory, so for very long files choose 150 DPI or convert a page range at a time. Each image is named with the original file name and a zero-padded page number so the files sort in order.
Your files stay on your device
Pages are drawn by pdf.js onto a canvas in your browser and encoded to PNG or JPG locally. The images exist only in your device memory until you download them, and the ZIP is built in a background worker. No page is ever uploaded.
Frequently asked questions
Which is better, PNG or JPG?
Use PNG for text, diagrams and sharp edges, and JPG for photographic pages or when you need small files.
What resolution should I choose?
150 DPI is a good default for screens and sharing. Use 300 DPI for print, and 72 DPI for quick previews and small files.
Can I convert only some pages?
Yes. Type a list such as 2-4, 9 in the Pages box. Leave it empty to convert every page.
Why is my ZIP so large?
High resolution PNG images are big. Try JPG, a lower DPI, or fewer pages.
Does it work on scanned PDFs?
Yes. A scanned page is already a picture, so the output looks the same as the scan at the resolution you pick.
