About PDF to JPG
Turning PDF pages into images is what you want when the destination cannot take a PDF: a slide deck, a marketplace listing, a social post, a support ticket, a document that has to be embedded somewhere expecting a picture.
Each selected page is rendered and downloaded as a separate image file, named after the original with its page number appended.
Resolution is the setting that matters. DPI controls how many pixels each page is rendered at. 150 is the default and right for anything viewed on screen — a standard A4 page becomes about 1240 by 1754 pixels, which is sharp on any display and produces a sensible file size. Use 300 if the image is going to print, which doubles the dimensions and roughly quadruples the file size. Going above 300 is almost always wasted: the extra pixels rarely carry extra information, since PDFs commonly contain images that were never that detailed to begin with.
Format. JPG is the default and correct for pages that are mostly photographs or scans. PNG is lossless and better for pages that are mostly text and line art, where JPG compression puts visible halos around letterforms. WebP is smaller than both and fine anywhere a browser is the destination.
What you lose. An image is pixels. Text stops being selectable or searchable, links stop working, and the file gets substantially larger than the PDF it came from. That is inherent to rasterising, not a limitation here. If you want the document to stay a document, don't convert it.
One useful side effect. Because rendering flattens everything to pixels, an image export genuinely removes hidden content — text under a black box, invisible layers, metadata. That makes it a crude but effective redaction step, and unlike PDF metadata stripping it also removes anything hidden in the page itself.
Pages takes the same range format as our other PDF tools: `1-3, 5, 8-`, or empty for all.
Rendering happens in your browser using the same engine Firefox uses to display PDFs. The document is never uploaded.
Questions
Is my PDF uploaded?
No. Pages are rendered in your browser by pdf.js — the same engine Firefox uses to display PDFs. The document never leaves your device.
What DPI should I use?
150 for anything viewed on screen, 300 for print. Above 300 is usually wasted, since PDFs often contain images that were never that detailed.
Why is the image bigger than the PDF?
A PDF stores text as instructions; an image stores every pixel. Rasterising almost always increases size, especially for text-heavy pages.
Can I get one image per page?
Yes — that is how it works. Each selected page downloads as its own file, named with the page number.
Does converting to an image hide sensitive content?
It removes anything not visibly rendered — hidden layers, metadata, text under a black box. It does not hide anything actually visible on the page.
