PDF → Images Converter

Are my PDF files uploaded to a server?

No. Every step — PDF parsing, page rendering, image encoding, and ZIP packaging — runs entirely in your browser using PDF.js and the Canvas API. Your files never leave your device.

What output formats are supported?

PNG (lossless), JPEG, and WebP are supported on all modern browsers. AVIF is available on Chromium-based browsers. The tool detects what your browser can encode and labels unsupported formats clearly.

What DPI / resolution can I export at?

Presets include 72, 96, 150, 300, and 600 DPI, plus a custom DPI field. At very high DPI (600 DPI on large pages) the output can exceed 4000 × 5600 px. The tool shows an estimated output size and warns you if memory usage may be high.

Can I convert only specific pages?

Yes. The Mode step lets you export all pages, a custom page range (e.g. "1-3,7,10-14"), pages you select in the preview grid, pages split by bookmarks into subfolders, or all imported PDFs at once in batch mode.

Can I export to grayscale or black-and-white?

Yes. The Color step offers Color, Grayscale, and Monochrome (1-bit) modes. Monochrome supports Floyd–Steinberg error diffusion and ordered (Bayer) dithering.

How do I download multiple pages?

All pages are bundled into a ZIP archive that you can download in one click. You can also use the File System Access API (Chrome/Edge) to save directly to a folder on your device.

Can I use this offline?

Yes, after the page has loaded once. PDF.js is loaded from a CDN on first use; subsequent loads use the browser cache. All processing is client-side and works without a network connection.

What is the OCR-optimise mode?

It presets the output to 300 DPI grayscale with contrast enhancement, which gives the cleanest input for external OCR engines. No OCR is performed by the tool itself — it only optimises the image quality for downstream use.
