About PDF to Image
This PDF to image converter uses pdf.js to convert each PDF page into PNG or JPEG bitmaps locally. Rendering uses the Canvas 2D API with custom DPI (72-300) and JPEG quality (0.1-1.0). pdf.js parses content streams, font subsets, and vector graphics, drawing pixel by pixel on Canvas. Multi-page documents can be packaged as ZIP or saved individually.

FAQ
PNG or JPEG, which to choose?
PNG preserves transparency with lossless compression, ideal for text and line-art pages; JPEG is smaller but lossy, suited for photo-heavy pages.
Can I adjust image resolution?
Yes. DPI is adjustable (72 to 300); higher DPI means clearer images but larger files. 72 DPI suits screens, 300 DPI suits printing.
How do I download multi-page PDFs?
Multi-page documents can be packaged as a ZIP for one-click download of all pages, or saved page by page as individual images.
Is text still clear after conversion?
Yes. pdf.js renders vector content on Canvas before exporting bitmaps; at sufficient DPI, text edges are sharp without aliasing.
Are files uploaded?
No. All rendering runs locally via pdf.js and Canvas API; files never leave your device, safe for sensitive documents.
