TL;DR: To convert PDF to PNG in high quality, open the free PDF to Image tool on PDFKits, select PNG as output, set the resolution — 150 dpi for screens, 300 dpi for print — and download. PNG is lossless, so text edges stay perfectly sharp where JPG blurs them. Everything runs in your browser; no upload, no account, no Adobe Acrobat Pro subscription at $14.99/month.
When you need a PDF page as an image — for a slide, a website, a print proof — the format choice decides the quality ceiling. PNG uses lossless compression, defined in the W3C PNG specification, so every pixel of the rendered page is preserved exactly. JPG's lossy compression discards data the algorithm judges invisible, which works for photos but smears text edges, fringes line art, and softens charts — exactly the content most PDFs contain.
PNG also supports alpha transparency (JPG converts transparent regions to solid white) and up to 48-bit color against JPG's 24-bit, which matters for brand assets and scientific figures with subtle gradients. The price is size: PNG files run two to five times larger than equivalent JPGs. Cloud converters like Smallpdf or iLovePDF handle the format swap, but they do it on their servers; PDFKits is a pdf to image converter that renders each page locally, so confidential decks and unpublished designs never cross the network.
A US Letter page renders at roughly 612 × 792 pixels: fine for thumbnails, email previews, and fast-loading web embeds, but small fonts go soft. Files stay tiny.
About 1,275 × 1,650 pixels per page. Text is crisp on standard and Retina screens; this is the right default for slides, documentation screenshots, and previews.
About 2,550 × 3,300 pixels per page, the standard for professional printing. Use it for brochures, posters, and any output that will hit paper, and for archival copies where future reuse is unknown.
Reserved for archival digitization and large-format print. Files balloon — a single page can exceed 100 MB — and above 300 dpi the visible gains on normal media are marginal. As a one-line rule: match dpi to the output medium, not to "maximum."
The decision is mechanical once you classify the page. Text, tables, line art, charts, screenshots, anything with sharp edges and flat color: PNG, always — lossy artifacts concentrate exactly where edges are. Full-page photographs with no overlaid text: JPG at quality 85–90 is usually indistinguishable and a fraction of the size. Mixed pages (photo plus caption plus chart): PNG if quality matters, JPG if you are emailing twenty of them. Subtle gradients — sky backgrounds, brand color fades — favor PNG too, since JPG quantization can introduce visible banding that PNG's lossless pipeline avoids. And if the destination requires transparency (logos over colored backgrounds, die-cut compositions), the choice makes itself: only PNG carries an alpha channel.
Best for: designers, marketers, researchers, and print professionals who need pixel-faithful page images without a software license.

Smallpdf's converter centers on JPG and applies its own quality presets; iLovePDF exposes a coarse quality toggle. Neither gives you a numeric dpi field, which is the setting that actually determines whether a journal or print shop accepts the file. For a single high-resolution export, the free browser route produces output identical to the desktop suites — the renderer draws the same page description defined by the PDF format. The paid tools earn their keep on batch automation, not on quality.
Converting at 72 dpi and printing it. Screen-resolution exports look blocky on paper. Decide the output medium first, then set dpi.
Using JPG for text-heavy pages. Compression artifacts halo every character. Reserve JPG for photographic pages where its smaller size pays off.
Rasterizing when you needed the embedded originals. Converting a page renders everything at one resolution; if you want the photos inside the PDF at their native quality, use Extract Images instead.
Converting all 80 pages for one figure. Pull the page first with Extract Pages, then convert — fewer files, faster processing.
Forgetting that PNG text is no longer text. A converted page is pixels: not selectable, not searchable, not accessible to screen readers. Keep the source PDF as the document of record.
PNG compression is lossless — no data is discarded — so photographic pages can be three to five times larger than JPG. For text and flat graphics the gap narrows, because PNG compresses uniform color regions efficiently.
The best resolution is the one matching your output: 72–150 dpi for screens, 300 dpi for print, 600 dpi for archival. Higher than the medium needs adds file size without visible benefit.
Yes. Select pages from the thumbnail view before converting — typical when you need a cover, one chart, or two figures from a long report.
Yes. Each page is rendered as a raster snapshot, so fonts, colors, and layout reproduce exactly at the chosen dpi. The trade-off: the result is an image, so text is no longer selectable or editable.
Not with PDFKits — rendering runs entirely in your browser and no server receives the file. That makes it suitable for NDA-covered decks, unpublished research, and client artwork.
A US Letter page (8.5 × 11 in) is about 2,550 × 3,300 pixels; A4 is about 2,480 × 3,508. Multiply inches by dpi to size any page.
Yes, when the transparency option is enabled: transparent regions export with an alpha channel instead of a white background. JPG cannot do this — it has no alpha support.
Both are lossless. TIFF is the convention in formal archives and supports multi-page containers; PNG is lighter, web-native, and universally viewable. For everyday archival of converted pages, PNG at 300 dpi is sufficient.
PDFKits converts one document at a time (all of its pages at once). For dozens of separate files, open multiple tabs; for hundreds on a schedule, a scripted CLI tool is the better fit.
Either re-convert at a lower dpi, or run the images through an image optimizer. If the destination accepts PDFs, compressing the source with Compress PDF often beats converting to images at all.
PDF to Image — export pages as PNG or JPG at your chosen dpi. Extract Pages — isolate pages before converting. Extract Images — pull embedded photos at native resolution. Compress PDF — shrink the source instead of rasterizing. Merge PDF — combine documents before export. Split PDF — break large files into convertible chunks.
