What this converter does
Some workflows need raster images of PDF pages: thumbnails for search results, page previews in a wiki, image inputs to a downstream tool. Rather than uploading the PDF to an online "PDF to image" service, this converter does the rendering entirely in your browser using Mozilla's pdf.js, the engine that powers Firefox's built-in PDF viewer.
Single-page PDFs produce a single JPG. Multi-page PDFs produce a ZIP of JPGs (one per page) created on the fly via streaming compression; nothing is held in memory longer than necessary.
DPI and quality
DPI controls how dense the raster output is. 72 DPI is screen-density; 150 DPI matches typical web display; 300 DPI is print quality. Higher DPI means larger output files and slower rendering. The default is 150.
JPG quality 1..100 controls the encoder. Default 90 is visually lossless for screen viewing.
Page range
Use range="first" (default) to convert just the cover page. Use range="all" to render every page. Use a range like "2-5" to pick specific pages. For single-page selections you can also pass a number.
Frequently asked questions
- Does this support encrypted PDFs?
- Not yet. PDFs that require a password to open will fail. We will add a password prompt in a later release.
- How big are the output files?
- A typical A4 page at 150 DPI renders to about 200-500 KB of JPG. ZIP overhead for multi-page output is negligible.
- Does this preserve the original PDF text?
- No. JPG is a raster format. To preserve searchable text use the original PDF, or convert to PNG and OCR it.
