1-3,5,8; page numbers start at 1.page-01, page-02 and so on.The commonest reason is that the other side can only take images. A chat window previews a picture inline while a PDF has to be opened as an attachment; social posts accept images in the body and nothing else; online forms often allow only JPG or PNG. The second reason is moving content into another document: dragging a chart into a slide or a report is simplest as an image, and the layout cannot shift on someone else's machine. The third is thumbnails and cover art — a preview of the first page next to an entry in a list.
It depends what is on the page. For pages that are mostly text, tables and vector charts, choose PNG: it is lossless, so strokes and hairlines do not turn into smudged blocks and the edges stay clean when you zoom in. For pages that are mostly photos or scans, choose JPG: at the same apparent quality it is usually a fraction of the size, and a photograph has no crisp edges that need protecting anyway. If you are unsure, export one page with the default PNG and look at it, then switch if it is wrong — the conversion happens in your browser, so trying a few times costs nothing.
PDF page sizes are measured in points, one point being 1/72 inch, so a 72 DPI export has exactly as many pixels as the page has points — the page at its native on-screen size. For everyday sharing 150 DPI is plenty; for printing, or for further editing in an image editor, choose 300 DPI. Beyond that there is little to gain: a low-resolution scan inside the PDF does not get any sharper because you exported at a higher DPI, it only makes the file bigger. Browsers also cap how many pixels a single canvas may hold; past that limit this tool steps the resolution down and says on the page what DPI it actually used, rather than quietly handing you a blank image.
This is worth settling before you start. Text in a PDF is a text object: it can be copied, searched, and read by search engines. Once the page is an image those words are pixels — not selectable, not searchable, and Ctrl+F finds nothing. Images are therefore good for "someone will look at this" and bad for "we may need to search this later". If your aim is to stop people copying the text, converting to images does work, but notice the flip side: you will not be able to search it either. When the text layer matters, do not convert — send the original PDF.
Converting to images re-renders the whole page picture; the page count does not change and one page gives one image. If a single page holds two pages' worth of content — a book scanned across the spread, an exam paper imposed on A3 — the layout has to be cut apart first, which is what Split PDF Pages does; convert after cutting and you really do get one image per page. To join several PDFs into one, or pull out a few pages by number, use Merge PDF. The other way round — you already have a pile of images and want them bound into one PDF — use Image to PDF.
No. Reading the file, rendering the pages, encoding the images and packing the archive all happen locally in your browser, so the contents of your PDF are never uploaded — which is what you want for contracts, internal material and unpublished documents. Once the page has loaded you can go offline and keep using it.
Exporting a single page downloads that image directly; exporting two or more packs them into one ZIP and downloads it in one go, named in the order page-01, page-02 and so on, where the number is the page number in the original PDF, zero-padded to match the document's length. If you only want one page, there is no need to change the range — just click "Download" under that page in the preview.
Choose 300 DPI for printing or for further editing in an image editor; for simply sending something to someone, 150 DPI is enough and less than half the size. But raising the DPI does not conjure up information that was not there: if the PDF is itself a low-resolution scan, exporting at 300 DPI just gives you a larger picture that is equally blurry. Vector charts and text, on the other hand, really are visibly sharper at a high DPI, because they are rendered for that resolution on the spot.
Browsers cap the total number of pixels in a single canvas, and past that limit some of them — Safari in particular — do not raise an error but simply hand back a blank image. So for an unusually large page, an A0 drawing at 300 DPI say, this tool lowers the resolution until it fits and states on the page what DPI it actually used. You get a slightly smaller but perfectly good image instead of a blank one that looks fine until you open it.
No. The text in an image is pixels: it cannot be selected, copied or found. If searchable text matters, do not convert — use the original PDF. If you just want to show someone a page, an image is the more convenient thing to send.
Yes. Switch "Export range" to "Selected pages" and type the page numbers; single pages and ranges can be mixed, for example 1-3,5,8 means pages 1, 2, 3, 5 and 8. Numbering starts at 1, a range written backwards is sorted ascending, and duplicates are removed. You can also export a single page straight from its "Download" button in the preview.
White. A PDF page has no background colour of its own, so without a base layer PNG would come out transparent and JPG, which has no alpha channel, would come out solid black. This tool therefore paints white underneath every page, which is also what almost everyone expects "what this page looks like printed" to mean.
It can. Each page's canvas is released the moment it has been rendered, so memory does not grow with the length of the document. Even so, at a high resolution every page is a large image, and exporting several hundred at once still takes real time and memory — you can hit "Cancel" at any point. The preview only renders thumbnails for the first 60 pages so the page does not stall on load; that has no effect on the export, which goes strictly by the page numbers you give it.
A PDF with a real open password cannot be read; the page says "password required" in so many words, so remove the protection before uploading. Files that merely show as "encrypted" in software such as WPS but open without a password are decrypted automatically and convert normally.
Yes. Rendering applies each page's own rotation, so the exported image is oriented exactly as it appears in your PDF reader — and the preview lets you confirm it before exporting.
