PDF to PNG

PDF TO PNG turns each page of a PDF into a lossless raster image, and here it happens without uploading the file anywhere. People reach for PNG over JPG because they need sharp text and clean lines (diagrams, charts, screenshots, contracts), and they are usually frustrated by server tools that demand an upload of a sensitive document, output blurry low-resolution images, or hide page limits and watermarks behind a paywall. This converter renders every page in your browser tab and gives you one PNG per page at the image size you choose.

What this conversion actually does (and does NOT do)

PNG uses lossless compression, so every pixel in the rasterized output is identical to the rendered PDF page. Text edges and thin hairlines stay crisp, with none of the blocky artifacts or halos that lossy PDF-to-JPG conversion smears around type and diagrams. That is the whole reason to pick PNG for document content.

What it does NOT do is keep your text. A PDF is vector and text plus embedded images; converting to PNG rasterizes (flattens) the page at a fixed size, after which the text is no longer selectable or searchable. Choose the size before you convert, because you cannot recover sharpness from a small PNG afterward. The size control sets the longest side of each image: 2048 px (default), 1600, 1200 or 800 px. Each page is drawn directly at that size from its vectors, so a higher setting gives a sharper image. At 2048 px an A4 page comes out at about 1449 × 2048 pixels (roughly 175 DPI) and a US Letter page at about 1583 × 2048; at 1200 px an A4 page is about 849 × 1200. There is no DPI selector and no 300 or 600 DPI option. 2048 px is plenty for screens, slides, documents, websites and ordinary office printing at small sizes, but not for high-quality print of a full A4 page, which needs about 2480 × 3508 pixels at 300 DPI.

The counterintuitive part is transparency. PNG supports an alpha channel, but this tool renders every page onto an opaque white background, so the PNGs it produces never have transparent areas. A "transparent background" PNG requires removing the white afterward in an image editor. One more thing about size: for pages that are full-page photographs, PNG files run several times larger than JPG at the same pixel size with no visible benefit, so PNG is the wrong pick there. A multi-page PDF produces one PNG per page, never a single stitched image, which is a common surprise.

When to choose PDF to PNG vs the alternative

Choose PNG when the page is document content: text, line art, tables, charts, diagrams, UI screenshots, or anything with hard edges and flat color. Lossless compression keeps it razor sharp and avoids the artifacts that show up most on text and thin strokes. Choose JPG (also spelled JPEG) instead when the page is a full-bleed photograph, because at the same pixel size a JPG is a fraction of the size with no visible quality loss for continuous-tone imagery. If you want to extract pages and pick PNG or JPEG with a maximum-dimension control, the more general PDF to images extractor covers both targets in one tool.

How to convert

1. Drop the PDF into the drop zone. It is read locally in your browser and never uploaded.
2. The output format is pre-selected to PNG (the JPEG path exposes a quality slider; PNG is lossless so it does not). Choose the image size for the longest side: 2048 px for the sharpest result, 1200 or 800 px for lighter files.
3. Click Extract All Pages, or type a page number and click Extract Page for a single page. Every page is rasterized in-browser.
4. All pages download as a ZIP of numbered PNG images, one file per page, with no page-count cap.

No upload. It runs on your device.

The conversion engine is PDF.js, the PDF renderer Mozilla built for Firefox, and it runs inside your browser tab. When you drop a PDF, the bytes are read into memory and rasterized locally, with zero network requests for the file itself. Once the page and its PDF engine have loaded, the conversion needs no connection. There is nothing to delete afterward because nothing was uploaded, and you can verify all of this yourself by opening the DevTools Network tab and watching that no request carries your document. This matters because PDFs routinely hold confidential material (legal contracts, medical records, financial statements, ID scans, signed HR paperwork) that should never transit a server you do not control. With local rendering there is no server-side copy to audit, leak, or breach.

No limits

Convert as many PDFs and as many pages as you want. There is no file-size cap, no page-count cap, no watermark on the output, no sign-up, and no ads.

Frequently asked questions

How do I convert a PDF to PNG without uploading it to a server?

Drop the PDF into this tool and the conversion runs entirely in your browser using PDF.js. The file bytes are read into memory and rasterized locally, so the document never travels to a server and there is no server-side copy to delete.

Does converting PDF to PNG lose quality?

No, the rasterization itself is lossless: PNG stores every pixel of the rendered page exactly, so text edges and thin lines stay crisp with no compression artifacts. The only thing you lose is the vector/text nature of the PDF, meaning the resulting image is no longer selectable or searchable.

Will each page of my PDF become a separate PNG file?

Yes, a multi-page PDF produces one PNG per page rather than a single stitched image. The pages are numbered and bundled into a ZIP so you get every page as its own file in one download.

What image size should I use, screen versus print?

Keep the default 2048 px for the sharpest result: an A4 page comes out at about 1449 × 2048 pixels (roughly 175 DPI), which suits screens, slides, documents and everyday printing at small sizes. Pick 1200 or 800 px when you want lighter files for the web or a form. The tool does not go above 2048 px, so it cannot produce 300 DPI images of a full A4 page for high-quality print; use a desktop renderer with a DPI setting for that.

How do I get a PNG with a transparent background from a PDF?

Not with this tool alone. Every page is rendered onto an opaque white background, so the PNG always has a white background, even if the PDF page has no background fill. Remove the white afterward in an image editor if you need transparency.

Is PNG or JPG better for converting a PDF?

PNG is better for document content like text, charts, diagrams, and screenshots because lossless compression keeps edges sharp. JPG (or JPEG) is better only for full-page photographs, where a PNG would be several times larger at the same pixel size with no visible benefit.

Can I batch convert several PDF files to PNG at once?

Yes, and because everything runs locally there is no file-count or page-count cap to work around. Select several PDFs and click Extract All Pages: you get one ZIP containing a ZIP of numbered PNG images per PDF.

Is it safe to convert a confidential PDF to PNG?

Yes, because the rendering is local, confidential content never transits a network and there is no server-side copy to breach or audit. You can confirm it by watching the DevTools Network tab while the conversion runs. A PDF that asks for a password to open cannot be read by this tool.

Why is my PDF to PNG output blurry, and how do I make it higher resolution?

Blurry output usually means a small size setting was chosen; pick 2048 px before converting, since you cannot add sharpness back later. Going from 800 px to 2048 px takes an A4 page from about 566 × 800 to about 1449 × 2048 pixels. That is the maximum: for 300 DPI print of a full A4 page, use a desktop renderer with a DPI setting.

Does this work offline, without an internet connection?

Yes, once the page and its PDF engine have finished loading, the conversion runs with no further network access.

Is there a page limit or watermark on the converted PNGs?

No, there is no page limit and no watermark is added to any output image. There is also no sign-up and no file-size cap.
