PDF to PNG Converter
File ToolsPDF pages as lossless PNG images, sharp enough for text and diagrams — never uploaded.
Your files never leave this device. Everything here runs in your browser — your files are never uploaded, stored or seen by us. Open your network tab and check.
PNG is lossless, so text and line art stay crisp — at several times the file size of a JPG.
Higher resolution means a bigger image, not more detail than the PDF holds.
Leave empty for every page, or write 1-3, 7 to pick.
Add a PDF. Each page is drawn to an image at the resolution you choose.
How this is calculated
PDF page (points) → pixels → PNG pixels = points ÷ 72 × dpi a point is 1/72 of an inch PNG lossless · crisp text and lines · larger file JPG lossy · smaller · soft edges around lettering Pages are drawn onto white, so the PNG has no transparency. Nothing is uploaded. The pages are rendered in this browser tab.
How it works
A PDF describes a page in points, a seventy-second of an inch, with no pixels in it at all. To make an image, each page is drawn onto a canvas at the resolution you choose: its width and height in points are divided by 72 and multiplied by the dots per inch. The pixel size of every page is shown before you convert, so there are no surprises in the download.
PNG is the right format for pages made of text, tables, charts and line drawings. It is lossless, so every letter keeps the sharp edge the PDF gave it — which matters when the image will be read closely, zoomed, printed or passed to text recognition. JPG discards detail to save space, and around lettering that shows as faint smudging.
The cost is size. In the worked example the same page was 398.4 KB as a PNG and 242.5 KB as a JPG. For a text page that is usually a price worth paying. For a PDF of photographs or scans — a brochure, a photographed receipt — JPG is the better choice, because PNG is poor at compressing photographic detail.
Resolution matters more than format for file size. Doubling the dpi quadruples the pixels; on a text page, where most of the area is plain white, the PNG grows less than that — from 398.4 KB to 898.7 KB at 300 dpi — but it still grows fast. 150 dpi is sharp on any screen; 300 dpi is for print and OCR.
Worked example
Page 1 of a real five-page A4 document, rendered with this page in Chrome 151 on 13 September 2026
- Page size 595.92 × 842.88 pt (A4, as Chrome prints it)
- At 150 dpi 595.92 ÷ 72 × 150 = 1241 px across
- 842.88 ÷ 72 × 150 = 1756 px down
- → PNG 398.4 KB lossless, crisp lettering
- → JPG 85% 242.5 KB smaller, detail discarded at letter edges
- At 300 dpi 2483 × 3512 px four times the pixels
- → PNG 898.7 KB 2.3 times the 150 dpi file
PNG at 150 dpi for reading on screen; 300 dpi for print or OCR
How to use it
- Drop a PDF in. Its page count and the size of each page are read in your browser.
- PNG is already selected. Choose a resolution: 150 dpi for screens and documents, 300 dpi for print and text recognition.
- Leave Pages empty to convert every page, or write a selection such as 1-3, 7.
- Convert, then download each page as its own PNG.
What this tool does not do
- The text becomes pixels. The PNG is not selectable, searchable or editable — that is what turning a page into an image means.
- PNG files are larger than JPGs of the same page, and much larger for pages that are photographs or scans. For those, convert to JPG instead.
- Pages are drawn onto a white background, so the PNG has no transparency, even where the PDF page itself has no background colour.
- 300 dpi is the ceiling offered. Browsers limit how large a canvas can be, mobile browsers far more tightly, and a very large page is rendered below the resolution you asked for. The result says which pages and what they came out at.
- Password-protected PDFs cannot be rendered. Remove the password first.
- One download per page rather than a zip.
- Rendering pauses if you switch to another tab, because browsers stop drawing for hidden pages, so a long document waits for you to come back.
Frequently asked questions
Should I convert a PDF to PNG or to JPG?
PNG for pages of text, tables, charts and diagrams, where sharp edges matter and lossless storage keeps every letter crisp. JPG for pages that are photographs or scans, where it makes a much smaller file with no visible difference. The same text page in the worked example was 398.4 KB as PNG and 242.5 KB as JPG.
What resolution should I choose?
150 dpi for anything read on a screen: an A4 page comes out about 1241 × 1756 pixels, comfortable to read at full width on any screen. 300 dpi for printing or for text recognition software, which reads small type more reliably at higher resolution. 72 dpi only for thumbnails.
Why is the PNG bigger than the JPG?
Because PNG keeps every pixel exactly and JPG throws some detail away. On a page of text, much of what JPG discards sits around the edges of letters, which is why PNG looks sharper and weighs more. For photographic pages the gap is far larger, which is when JPG is the better choice.
Will the text in the image still be selectable?
No. A PNG is a picture of the page, so the words are pixels rather than text. If you need to copy the text, use the PDF itself.
Is my PDF uploaded anywhere?
No. The pages are rendered in your browser with pdf.js, and no network request carries your document. You can check: open your browser's network tab before converting and watch that none of them does — the only requests you will see after the page loads are small ones recording that the tool was used.
Can I convert only some pages?
Yes. Write the pages you want in the Pages field — for example 1-3, 7 — and only those are rendered. Leave it empty to convert the whole document.
Is this different from PDF to JPG?
It is the same renderer, opened with PNG selected, and the advice on this page is about PNG output. You can still switch to JPG before converting.
