About PDF to PNG Conversion
- • Runs entirely in your browser — the PDF is never uploaded to a server
- • Rendered with pdf.js, the same engine Firefox uses to display PDFs
- • PNG is lossless, so text and line art stay perfectly sharp — no JPEG ringing
- • Optionally keep the alpha channel so pages layer over other backgrounds
- • Rasterising converts text into pixels, so the output is no longer searchable
- • Download pages individually, or grab every page as a single ZIP archive
About PDF to PNG Converter
This PDF to PNG converter renders each page of a PDF into a lossless PNG image using Mozilla's pdf.js engine. Unlike JPEG, PNG stores every pixel exactly as rendered with no compression artefacts, and it carries an alpha channel so pages can keep a transparent background. Rendering happens locally in your browser; the PDF is never transmitted.
Why use a PDF to PNG Converter?
PNG is the right format when the page is mostly text, tables, diagrams, or line art. JPEG's lossy compression produces visible ringing around sharp glyph edges, while PNG keeps them crisp. PNG's transparency support also makes it the format of choice when a page needs to be layered over another background in a design tool or slide.
Who is it for?
Aimed at people who need pixel-exact page images: designers placing a logo sheet into a layout, documentation writers embedding diagram pages, developers generating crisp page thumbnails, and anyone preparing screenshots of contracts or invoices where text must stay legible.
How to use the tool
Drag a PDF onto the drop zone, or click it to browse for a file
Wait for the page count and first-page preview to appear
Choose a render resolution — 150 DPI for screens, 300 DPI for print-quality output
Decide whether to keep the background transparent or composite the page onto white
Optionally enter a page range such as 2-5 to convert only part of the document
Click Convert and watch the per-page progress indicators
Download pages individually, or use Download All to get them as one ZIP archive
Frequently Asked Questions
How do I convert a PDF to PNG?
Drop your .pdf file onto the upload area or click to browse. The tool reads the page count, then renders each selected page to a canvas at your chosen resolution and encodes it as PNG. Pick a DPI — 150 suits screen use, 300 matches print quality — and optionally narrow the output with a page range such as 2-5. Click Convert, then download pages one by one or as a single ZIP. Because PNG is lossless there is no quality slider to tune.
Is my PDF uploaded to a server?
No. Everything runs in your browser via JavaScript — the file is read into memory with the FileReader API, rendered by pdf.js, and encoded by your browser's canvas. Nothing reaches a server and nothing is logged. Open DevTools' Network tab to confirm: once the page and the pdf.js worker have loaded, converting fires zero further requests, and the tool keeps working with networking disabled. That makes it safe for contracts, invoices, and medical records.
PDF to PNG or PDF to JPG — which should I pick?
Match the format to the page content. PNG is lossless and encodes sharp edges perfectly, so pages of text, tables, diagrams, and line art stay crisp — JPEG produces visible ringing around high-contrast glyph edges. JPEG's lossy compression is far more efficient on photographic content, so scanned photos and image-heavy brochures produce much smaller files as JPG. As a rule: text and vector pages go to PNG, scanned or photographic pages go to [PDF to JPG](/tools/pdf-to-jpg/).
Can the output keep a transparent background?
Yes, and this is PNG's main advantage over JPEG here. Most PDF pages do not actually paint a white background — the white you see in a reader is the viewer's canvas showing through. Enable the transparent background option and any area the page does not paint stays fully transparent, which is what you want when layering a page over another design. Leave it off and pages are composited onto white, matching how the document would look printed.
Why are the PNG files so much larger than JPG?
PNG uses lossless DEFLATE compression, so every pixel is preserved exactly and nothing is discarded. JPEG throws away visual information that is hard to perceive, which is why it achieves far smaller files on photographic content — often five to ten times smaller. On pages of flat-colour text PNG closes much of that gap, because large uniform regions compress efficiently. If a PNG page is bigger than you want, run it through our [PNG Compressor](/tools/png-compressor/), which reduces size without visible loss.
What DPI should I use?
DPI sets how many pixels each inch of the page becomes. PDF pages are measured in points at 72 per inch, so the render scale is DPI ÷ 72. At 150 DPI a US Letter page (612×792 points) becomes 1275×1650 pixels, which is ample for screen viewing. At 300 DPI the same page renders to 2550×3300 pixels, the standard for print reproduction, but memory use and file size both grow with the square of the scale. Above 300 DPI the visible gain is small.
Is the text in the PNG still searchable?
No, and this is the defining trade-off. A PDF stores text as characters plus font references, which is why you can select and search it. Rendering converts those characters into a grid of pixels, so the result is a picture of text — Ctrl+F finds nothing and screen readers cannot read it, which makes the output inaccessible. If you need the text back, run the PNG through our [Image to Text](/tools/image-to-text/) OCR tool, bearing in mind that OCR is an approximation and misreads unusual fonts.
Can it handle password-protected PDFs?
Only files you can already open without a password. PDFs carry two kinds of protection: an owner password, which merely sets permission flags that pdf.js ignores, and a user password, which genuinely encrypts the content streams. Owner-password documents convert normally. User-password documents cannot be rendered without the password, and the tool reports the file as encrypted rather than producing a broken result. Decrypt the file in a reader you have the password for, then convert the decrypted copy.
