How to convert PDF to PNG

Four steps, all running locally in your browser.

01

Confirm PNG is selected

PNG is the tool's default output format. Just pick a resolution before you drop your file — settings can't be changed once rendering starts.

02

Drop your PDF

One PDF at a time. Nothing is uploaded, it's processed on your device.

03

Watch pages render

Pages appear one by one as they finish. Download any finished page immediately, without waiting for the rest.

04

Download individually or all at once

Grab a single page any time, or wait for the document to finish and download every page as one ZIP.

When to choose PNG over JPG for PDF conversion

The choice between PNG and JPG comes down to what your PDF contains and what you are doing with the output.

Text-heavy documents

PNG renders body text, headings and captions with sharp edges. JPG compression blurs characters at high zoom.

Technical diagrams

Charts, flowcharts, engineering drawings and infographics need PNG to preserve line accuracy and label readability.

Presentations and slides

Slide content with text on coloured backgrounds converts better to PNG. JPG creates banding in flat-colour areas.

Further editing

If you plan to edit the extracted image in Photoshop, Figma or another tool, PNG is the correct archival format.

Screenshots and UI

PDFs created from screenshots or web pages render with sharper interface elements in PNG.

Certificates and forms

Official documents with fine borders, seals and text remain legible at smaller sizes with PNG.

For PDFs with photographic content where file size matters more than sharpness, use the PDF to JPG converter instead.

What "lossless" actually gets you from a PDF page

Rasterizing a PDF page losslessly means every pixel matches exactly what was drawn on that page, nothing more. It doesn't automatically mean the background becomes transparent, and it doesn't automatically mean it stays solid either — the PNG here is rendered onto a transparent canvas with no background pre-fill, so whether a page comes out looking solid white depends on whether that page's own content explicitly painted a white background. Most document pages, whether from Word, Google Docs or a report template, do include that explicit fill and will faithfully reproduce a solid white background rather than dropping it out.

Transparency only survives if the PDF never had a background

A logo or graphic exported to PDF from design software without a filled background layer can genuinely carry through as a transparent PNG, since there was never any opaque content behind it to render. Pulling a logo out of a full page letterhead or brochure layout won't give you the same clean result, since the page itself was designed with a background. For that kind of extraction, you generally need the graphic isolated on its own page or its own file to begin with.

Watch file size on pages that mix text and photos

PNG compresses flat text and vector content extremely well, but a single page that combines body text with an embedded high-resolution photo, common in brochures or annual reports, drags the whole file size up, since the compression has to handle the busy photographic region too. If one page in a batch comes out unexpectedly large next to its neighbors, a mixed layout like this is usually why.

PNG holds up better when the output is headed for OCR

If the extracted pages will later go through optical character recognition, PNG's lack of compression artifacts around character edges gives OCR software cleaner input than a JPEG, where softened edges around letters can quietly hurt recognition accuracy. For scanned text you plan to keep searchable long term, PNG is the safer archival choice over JPEG.

Common PDF to PNG mistakes

Assuming a plain document page always exports as solid white

PNG output is rendered onto a transparent canvas with no pre-filled background, unlike JPEG output here, which is always filled white first. Whether a page comes out solid depends on whether the PDF page itself painted a background — a page that looks white in a viewer only stays white if it actually drew that white.

Extracting a logo from a full-page layout and expecting a clean cutout

Transparency only survives when the source PDF page never had a background to begin with. Pulling a logo out of a full letterhead or brochure page won't isolate it, since the surrounding page content is still there behind it.

Changing resolution after dropping the PDF

The settings controls disappear once rendering starts. Click New PDF and drop the file again with your new resolution selected first.

Assuming this works fully offline from the moment the page loads

Your PDF's content is never uploaded, but the PDF.js worker script itself is fetched from a CDN the first time you convert a file in a session. Convert one PDF while online if you want to rely on the tool fully offline afterward.

Waiting for the whole document before downloading anything

Each page is downloadable the moment it finishes rendering. The "Download all" ZIP button only appears once every page is done.

Frequently asked questions

Why is PNG better than JPG for converting PDF text and diagrams?

PNG uses lossless compression. Every pixel in the output is an exact representation of the rendered PDF page. JPG uses lossy compression, which introduces artefacts around high-contrast edges like text and line drawings. For PDFs with text, charts, technical drawings or sharp graphics, PNG is always the better choice.

How do I convert a PDF to PNG without uploading?

Pick your resolution first — PNG is already selected by default — then drop your PDF. The pages render locally in your browser using PDF.js. Nothing about your document is sent to a server, and settings can't be changed once rendering has started, so set them before you drop the file.

Will there be a watermark on the PNG output?

No. The output PNG files have no watermarks. All processing runs locally in your browser with no service involvement.

What resolution is best for PDF to PNG conversion?

For web sharing, Screen (72 DPI) gives small files. For presentations and documents, HD (144 DPI) is the best balance and the tool's default. For printing or high-fidelity archiving, Print (216 DPI) gives the sharpest results. Text-heavy PDFs benefit most from the higher resolutions.

Does the PNG output preserve transparency?

It depends entirely on the source PDF. PNG output here is rendered onto a transparent canvas with no background fill, unlike JPEG output, which is always pre-filled white since JPEG can't store transparency. So whether a page comes out solid or transparent depends on whether that page's own content explicitly painted a background. Most ordinary document pages do include an explicit fill and come out looking solid white, but a page that never painted a background, common for isolated logos or graphics, can come back genuinely transparent even if it looked plain white in a PDF viewer.

Can I convert just one page?

Yes. Pages appear as individual thumbnails as they finish rendering, and each one is downloadable the moment it's ready, you don't need to wait for the rest of the document. Click any page or hover and click the download button to save just that one as a PNG.

Is my PDF private?

Your PDF's content never leaves your device — all rendering uses PDF.js running locally in your browser. The one exception is the PDF.js worker script itself, which is fetched from a CDN the first time you convert a file in a session; that's a request for the library code, not your document. If you want to rely on the tool fully offline, convert one PDF while connected first.
