立即试用常见问题
Upload your PDF and every page is rendered to a PNG automatically — no settings required to get started. Each page appears as a thumbnail you can click to download individually, or use the Download all images button to save every page in one go. You can switch the resolution between 150, 200, and 300 DPI at any time and the pages re-render automatically.
usageYes, it is completely free. There is no signup, no watermark, and no per-page limit — you can convert PDFs up to 50 MB. Your files are processed on our secure servers and auto-deleted, so nothing stays on our systems after you download your images.
pricingChoose PNG when sharpness matters: it is a lossless format, so text, tables, line art, and diagrams keep crisp edges with no compression artifacts. Choose JPG when file size matters more, such as photos or email attachments. This page always outputs PNG; if you want JPG or to compare both, use our PDF to Images tool which offers both formats.
formatsUse 150 DPI for on-screen viewing and web pages, 200 DPI as a good all-round default, and 300 DPI when you need print quality or plan to zoom into fine detail. Higher DPI means larger PNG files, so pick the lowest resolution that still looks sharp for your use.
settingsNo. PDF pages are rendered the way they print, on a white page background, so the PNGs have a solid white background rather than transparency. If you need a transparent version of a graphic, download the PNG and run it through our Remove Background tool.
formatsEvery page is rendered, but you download only what you need — each page thumbnail is its own download link, so you can grab a single page without saving the rest. If you regularly need just a section of a large PDF, split it first with our PDF Split tool and convert the smaller file.
usagePDF to PNG 如何助您完成任务
它每天都在解决真实的问题——服务企业、创作者和日常任务。找到适合您的用例,几秒即可开始。
Put PDF pages into slides and docs
Slide and document editors handle images far better than embedded PDFs. Convert the pages you need to PNG at 200 or 300 DPI and paste them into PowerPoint, Google Slides, Word, or Notion with text that stays sharp at any zoom.
Share PDF content on the web and social media
Websites, chat apps, and social feeds preview images instantly but often refuse or hide PDF attachments. Render your one-pager, infographic, or menu as PNG pages so they display inline everywhere.
Print-quality page exports
At 300 DPI each PNG is a print-ready raster of the page — useful for sending single pages to print shops, embedding figures in academic papers, or archiving signed documents as tamper-evident images.
Feed PDF pages into image pipelines
OCR engines, image classifiers, and annotation tools take images, not PDFs. Batch-render a scanned document to lossless PNGs so downstream tools work from the sharpest possible source.
