LOCAL PDF RENDERING
Render PDF pages as PNG images
Each selected page is rendered in this browser and downloaded as a real PNG. Your PDF never leaves this device.
使用步骤
如何使用
- Choose one local PDF up to 50 MB.
- Select all pages or a page list, then choose the render scale.
- Convert and download each page as a real PNG; cancel or clear the page when finished.
Local rendering and privacy
The PDF is opened from the file you select with PDF.js and rendered in your browser. No PDF bytes or page images are sent to a server, remote URL, or CDN. Temporary Canvas elements are released after each page is encoded.
Page, pixel, and memory limits
A PDF may be up to 50 MB and 100 pages. You can render all pages or a list of pages. Each output page is limited to 40 megapixels and 256 MB of Canvas memory; the selected scale is checked before rendering.
Output behavior
Each page is downloaded as a genuine image/png file. PDF vector content becomes pixels, page order follows your selection, and pages without a painted background retain transparency where the browser PDF renderer provides it.
常见问题
你可能还想知道
Is my PDF uploaded?
No. The PDF and rendered PNGs stay in your browser memory.
Can I convert only some pages?
Yes. Enter all, a single page such as 2, or ranges such as 1,3-5.
Why was my PDF rejected?
The converter rejects non-PDF bytes, damaged files, password-protected files, PDFs over 50 MB or 100 pages, and pages that exceed the selected pixel or memory limit.
Does PNG preserve selectable PDF text?
No. PNG is a raster image of the rendered page and does not contain selectable PDF text or vector objects.
