PNG keeps rendered pixels intact
PNG uses lossless compression, so repeated opening does not add JPEG-style artifacts. It is a strong choice for PDF pages containing small text, line art, charts, interface elements or flat-color diagrams.
What conversion preserves
The visual appearance of each successfully rendered page is captured as pixels. PDF.js handles the page inside the browser. Searchable text, hyperlinks, forms and vector editability do not remain in the resulting PNG image.
PNG versus JPG
Use PNG when crisp edges and lossless pixels matter. Use JPG for smaller photo-heavy page previews and easier sharing. Both workflows create one image per page and can package multiple results in a ZIP archive.
Browser resource limits
High-resolution pages and long documents use significant memory. If a large PDF strains a phone or tablet, process fewer documents at a time on a desktop browser. Password-protected or malformed documents may not render.
- Select a PDF.
- Wait for local page rendering.
- Download PNG pages individually or as a ZIP.
