What PDF to PNG does
This converter renders each page of a PDF as a PNG image at twice screen resolution — about 144 dpi, or 1,190 × 1,684 pixels for an A4 page — and offers every page as a separate download. PNG is lossless, so text, lines and diagrams come out perfectly sharp with no JPEG halos, and any transparency in the page is kept. Rendering uses PDF.js in your browser; the document is never uploaded.
PNG or JPG?
| PNG | JPG | |
|---|---|---|
| Text and line art | Perfectly sharp | Faint halos around edges |
| Photographic pages | Large files | Small files, no visible loss |
| Transparency | Kept | Filled with white |
| Typical A4 text page | 150–400 KB | 80–300 KB |
| Typical photo page | 2–5 MB | 300–600 KB |
| Best for | Documents, slides, diagrams, forms, anything to be edited | Scans, photo-heavy pages, sharing where size matters |
For most documents — the typical mix of text and a few graphics — PNG is the better default. Switch to PDF to JPG for scanned books, photo albums, or when a size limit bites.
Common uses
- Slides and figures in documents — insert a page into Word, Google Docs, Keynote or Notion as a crisp image.
- Website and app screenshots of a form, certificate or brochure page.
- Image-only uploads — forms that accept PNG or JPG but not PDF.
- Annotating — mark up a page in any image editor, which is often easier than in a PDF tool.
- Thumbnails and previews for document libraries and product pages.
- OCR pipelines that take images rather than PDFs.
What is lost in the conversion
- Text becomes pixels — not searchable or selectable. Use PDF to TXT if you need the words.
- Vector graphics are rasterized at 144 dpi; fine for screens and ordinary printing, not for enlargement.
- Links, form fields and annotations are flattened into the picture.
- Fonts not embedded in the PDF are substituted, as in any viewer.
Tips
- Extract the pages you need first with Extract Pages to avoid rendering and downloading a whole document.
- If the destination shows the image small, crop to the region of interest rather than relying on the viewer to zoom.
- For a higher-resolution export (300 dpi for print), use a desktop tool such as Acrobat, Preview or ImageMagick.
- Allow multiple downloads when the browser asks, or only the first page will be saved.
Frequently asked questions
What resolution are the PNGs?
144 dpi — twice the PDF's nominal 72 dpi. An A4 page is about 1,190 × 1,684 px; US Letter about 1,224 × 1,584 px.
Can I get one image containing all pages?
Not directly. Convert the pages, then stitch them in an image editor; or use N-Up to place several pages on one PDF page first and convert that.
Why is a scanned page so large as PNG?
Scans are photographic content, which PNG compresses poorly. Use PDF to JPG for scans.
Does it work on password-protected PDFs?
No. Unlock the file first with Unlock PDF (you need the password).
Is the page background transparent?
PDF pages have an implicit white background, so the PNG is white unless the page explicitly draws transparency.
Is the PDF uploaded?
No. Rendering is done by PDF.js in your browser.
