PDF to PNG Converter

Convert PDF to PNG Online — Lossless, Transparency-Preserving

To convert PDF to PNG, upload your PDF, pick a DPI (300 for print, 150 for screen), and click Convert. Each PDF page becomes one PNG image. PNG uses lossless compression, so text and line art stay perfectly sharp, and it preserves any transparency the page already has — the key advantage over PDF to JPG.

Real result: a 10-page PDF rendered at 300 DPI produces 10 numbered PNGs (page-1.png, page-2.png, ...), delivered individually or as one ZIP. Need smaller, photo-friendly files instead? Use PDF to JPG.

How to Convert PDF to PNG Online

1. Upload Your PDF: Drag and drop or click "+ Add Files" to select PDFs from your computer. Batch upload is supported — every page across every file becomes its own PNG.
2. Pick Conversion Quality (DPI): The default is 300 DPI for print-quality output. Drop to 150 DPI for screen viewing and email, 200 DPI for everyday documents, or push to 600 DPI for archival scans. Higher DPI means sharper output and larger files.
3. Set Image Transparency and Resolution (Optional): Under Image Transparency, set the Color to keep the background white or pick another solid color — alpha transparency is preserved when the PDF page itself contains transparent elements. Optionally override the rendered output via Image resolution (Preset Resolutions like 1080P, a Width x Height, or a Resolution Percentage of the original).
4. Convert and Download: Click "Convert". Each PDF page produces a numbered PNG (page-1.png, page-2.png, ...). Download files individually or grab them all as a ZIP archive. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert PDF to PNG?

PNG is the right output when you need pixel-perfect rasters of PDF pages — text stays sharp, line art stays clean, and transparency is preserved. Unlike JPG, PNG uses lossless compression, so a 300 DPI PNG of a contract page is mathematically identical to what the PDF renderer produced. That matters whenever the page will be re-edited, posted to the web at native resolution, or printed.

• Web publishing without JPG artifacts — embed pages of a brochure, infographic, or product spec sheet in a blog post or knowledge base. PNG keeps headline type and chart gridlines crisp at any zoom level.
• Design and marketing assets — pull a logo, a one-pager, or a product mockup out of a PDF and drop it into Figma, Photoshop, or Canva. PNG's alpha channel preserves transparent backgrounds for compositing.
• Slide decks and document thumbnails — generate page previews for Google Slides, Keynote, or a SharePoint document library. At 150 DPI, a US Letter page renders as 1275 x 1650 px — sharp enough for full-screen presentation.
• OCR and computer vision pipelines — Tesseract, AWS Textract, Azure AI Document Intelligence, and Google Document AI all accept PNG inputs. 300 DPI rasterization is the industry default for English-language OCR accuracy.
• Print and archival — 300 DPI matches commercial print resolution, and PNG's lossless storage means archived pages don't lose detail over repeated copies or color-managed workflows.
• Sharing pages on platforms that strip PDFs — Instagram, Slack inline previews, X, Reddit, and most CMS image uploaders accept PNG but reject or flatten PDF. Convert per page and post directly.

PNG vs JPG vs WebP for PDF Rasterization

For text-heavy PDFs and anything with sharp edges, PNG is the safe default. Pick PDF to JPG for photo-heavy PDFs where 30-50% smaller files matter more than perfect sharpness, or PDF to WebP when the destination is a modern web page and you control the rendering surface.

DPI Cheat Sheet (US Letter, 8.5 x 11 in)

Sizes are typical for mixed text-and-graphics pages and grow with the amount of image content on the page. A pure-text page compresses much smaller than a page with photographs.

Transparency: When to Keep It vs Flatten to White

PDF pages can carry transparent elements — overlay logos, watermarks on a clear background, design layers without a fill. The xconvert Image Transparency control lets you choose: keep transparency (alpha channel) or flatten to a solid color (the default is white, but you can pick any of the named palette colors).

• Keep transparency when the PNG will be composited onto another background — overlay marks, logo extractions, sticker assets, design elements destined for Figma or Photoshop.
• Flatten to white for printing, OCR, document sharing on Slack/email, and any platform that doesn't render alpha cleanly (some old CMSes and Office versions show a black background where alpha was intended).
• Flatten to a brand color when the PDF was authored for one background but you need the export to match a different theme (dark-mode docs, branded slide decks).

Frequently Asked Questions

Does each PDF page become a separate PNG?

Yes. A 10-page PDF produces 10 numbered PNGs (page-1.png through page-10.png). They're delivered as individual downloads or bundled into a single ZIP archive. PNG itself has no multi-page container — that's a feature of formats like TIFF or PDF, not PNG.

What DPI should I use?

150 DPI for screen viewing, slide decks, and email attachments. 200 DPI for everyday document sharing where text needs to remain comfortably readable when zoomed. 300 DPI for printing, OCR, and any case where you might later re-export or crop. 72 DPI only for tiny web thumbnails. Doubling the DPI roughly quadruples the pixel count and file size, so don't pay for resolution you won't use.

Will the PNG keep a transparent background?

Only if the source PDF page itself contains transparent elements. PDFs authored for print typically have a white page background — converting those produces a PNG with white pixels, not transparency. PDFs authored as design assets, single-element exports, or with a transparent page color produce PNGs with a real alpha channel. Use the Image Transparency control to flatten to a chosen background color when you don't want alpha.

Why is my PNG so much larger than the original PDF?

PDF stores text as glyphs (a few bytes each) and vectors as math; PNG stores rasterized pixels. A 50 KB PDF page rendered at 300 DPI can easily produce a 1.5 MB PNG because you're now storing every pixel of every letter. That's expected — drop the DPI to 150 if file size matters more than print sharpness, or convert to WebP for roughly 26% smaller lossless files at the same visual quality.

Is PNG truly lossless compared to JPG?

Yes. PNG uses DEFLATE compression (the same algorithm as ZIP), which is mathematically reversible — no pixel data is discarded. JPG uses DCT-based lossy compression and discards high-frequency detail, which is what produces the "fuzzy text" artifacts around sharp edges in document conversions. For any PDF with text, diagrams, or screenshots, PNG keeps things crisp where JPG smears them.

Can I convert only specific pages?

Use Split PDF first to extract the page range you want, then convert the resulting PDF to PNG. That keeps the workflow simple and avoids re-uploading the whole document just to throw most pages away.

What's the maximum file size or page count?

There is no fixed page-count cap. Very large PDFs (hundreds of pages at 300 DPI) will produce hundreds of megabytes of PNG output — upload size and your connection speed will be the practical limit, since the file is uploaded to our servers for rendering. For large jobs, drop to 150 DPI, split the file into smaller chunks via Split PDF, or export every page at once with PDF to Images.

Can I go the other way and combine PNGs back into a PDF?

Yes — use PNG to PDF for a single image or Merge images to PDF when you have many. Round-tripping is lossless on the PNG side, so re-merged PDFs preserve everything except text searchability (since the PDF now contains rasters, not glyphs — run OCR if you need search).

How do I make the PNG smaller without dropping DPI?

Run the output through Compress PNG after conversion. PNG compression is lossless by spec, but smart re-encoding (palette reduction, filter optimization, removing metadata) typically saves 20-50% on document-rendered PNGs without any visible quality loss.
