Frequently Asked Questions
What DPI should I choose for PDF to image conversion?
72 DPI is screen resolution — suitable for web display and thumbnails. 96 DPI is standard screen resolution on Windows. 150 DPI is a good balance between file size and quality for most purposes. 300 DPI is print quality — use this if you plan to print the output or need fine detail. Higher DPI produces larger files.
What is the difference between PNG, JPG, and WebP output?
PNG is lossless and supports transparency — ideal for PDFs with white or transparent backgrounds. JPG is lossy compression that produces smaller files, best for photographs and images with many colors. WebP offers the best compression at comparable quality to JPG, with transparency support, but requires a modern browser or app to view.
How do I convert only specific pages?
After uploading, use the "Single page" option to convert one page by number, or the "Page range" option to convert a consecutive range (e.g., pages 3 to 7). The "All pages" option converts every page in the PDF.
How are multiple pages downloaded?
When converting more than one page, a "Download ZIP" button appears. This creates a ZIP archive containing all converted images named with the original PDF filename and the page number (e.g., document-page1.png). You can also download individual pages using the download button on each image card.
Is my PDF uploaded to a server?
No. The tool uses PDF.js (Mozilla's open-source PDF rendering library) entirely in your browser. Your PDF is loaded into browser memory using the ArrayBuffer API and each page is rendered to a canvas element. The resulting images are created using canvas.toBlob() — no server is involved at any point.
