PDF to JPG

DPI, dots per inch, controls how much detail each rendered image carries, and it is worth picking deliberately rather than defaulting to the highest number. 150 DPI is genuinely enough for anything staying on a screen, an email attachment, a slide, a webpage, and keeps file sizes reasonable. 300 DPI is the standard target once printing is involved, or when a page has small text that needs to stay legible when someone zooms in. Going higher than 300 rarely helps and mostly just produces larger files.

Format matters too, and it is not just a preference. JPG uses lossy compression, which is fine and expected for photos or scanned pages with continuous color and shading, and it keeps file sizes down. PNG is lossless, which makes it the better choice when a page is mostly sharp text, line art, or anything with hard edges and flat colors, screenshots and vector-style diagrams both fall into this category, since JPG's compression tends to introduce visible artifacts around sharp edges that PNG does not.

This gets used for pulling one slide out of a deck to paste into an email without attaching the whole presentation, turning a scanned form into an image to embed on a webpage, or extracting a diagram or chart from a PDF manual for use somewhere else. In each case the underlying need is the same: getting page content out of the PDF container and into a format that is easier to drop into something else.

One real limit worth knowing before you upload: documents over 50 pages are not accepted for this tool right now, since rendering that many pages at once is a heavier job than the tool is built to queue. For anything longer, splitting it into smaller sections first with Split PDF and converting each piece separately works around this cleanly.

Output comes back as either a set of separate image files or one zip, and which one you want depends on what happens next. A single page or two, separate files are easier to grab individually. A full document's worth of pages, the zip is the better choice, since downloading twenty separate images one at a time is exactly the kind of tedious step this tool exists to avoid.

It is worth being clear about what this tool does not do: it produces pictures of your pages, not text. A rendered JPG of a page looks correct but cannot be searched, copied, or edited as text, since as far as a computer is concerned it is one solid image, the same as a photograph. If what you actually need is the words on the page in an editable form, image conversion is the wrong tool for that job, even though the two get confused often enough that it is worth spelling out here.

A useful way to think about the two quality settings together: DPI controls the resolution of each image, format controls how that resolution gets stored. Choosing 300 DPI with JPG at its most aggressive setting can still look soft, since a high-resolution image saved with heavy lossy compression loses detail regardless of how many pixels it started with. If sharpness genuinely matters, print quality means both a higher DPI and a format suited to what is actually on the page, not one setting compensating for the other.
