Convert PDF pages into images

Turning PDF pages into image files

Some places only accept an image, not a PDF. An ID-upload system asks for a photo of a document and rejects anything with a .pdf extension, even though the content is identical. An online form has an attachment field that only recognizes JPG or PNG. A slide deck needs each page of a PDF as a separate image, to paste into a program that can't read PDF directly. In every one of these cases, the document already exists — it just needs to be reshaped into the format the destination asks for.

This tool handles exactly that step: you upload a PDF, choose which pages you want, in which format and at which resolution, and it hands back an image file for every page — nothing to install, and the file never leaves your computer, because the whole process runs inside your browser.

Picking pages, format, and resolution

Page selection uses the same syntax as the other PDF tools on this site: a range like "1-5", specific pages like "2,4,7", an open-ended range like "3-" through the end, or leave it empty to convert the whole document. The output format can be JPG, PNG, or WebP — JPG and WebP with a quality control, PNG without one, since its compression is always lossless. Resolution has three options: low, at 72 DPI, enough for viewing on screen; medium, at 150 DPI, the default, which balances sharpness and file size; and high, at 300 DPI, meant for printing, which produces considerably larger files. Next to each resolution option, the tool shows the approximate pixel dimensions the result will have, calculated from the actual size of the first page of the PDF you uploaded.

Converting many pages at 300 DPI at once uses a fair amount of browser memory, because each image at that resolution is considerably larger than the same page at 72 or 150 DPI. The tool warns you when that combination — high resolution with a large number of selected pages — is likely to make the process heavier than usual.

A preview with real thumbnails

Unlike other PDF tools on this site, which only show a numbered list of pages, this one shows real thumbnails of each page's actual content. That's possible because converting to image already requires loading a library capable of drawing a PDF's content (pdf.js) — once it's loaded, generating a small preview version of each page is a natural next step, with no extra dependency cost.

That library is relatively heavy, so it only loads after a PDF is dropped into the tool — never on the page's initial load. For very long documents, generating a thumbnail for every single page would make the preview slow to appear, so it's limited to the first pages of the file; the final conversion, on the other hand, processes every page you select, regardless of that preview limit.

The result is an image, not a document anymore

It's worth stressing a difference that isn't obvious: the generated image is a visual snapshot of the page, not a copy of the document with text underneath it. After conversion, it's no longer possible to select, copy, or search the text that was on that page — even if the original PDF had perfectly selectable text, the resulting image doesn't retain that information, only the appearance.

The original file goes through a real check as soon as it's uploaded: the tool actually tries to open the PDF, it doesn't just trust the file extension. If opening fails, the file is flagged as invalid. If the PDF has a password or some kind of restriction, it's detected as protected — this tool doesn't remove passwords or bypass that kind of protection, so a protected PDF can't be converted here.

Downloading the result

When only one page is converted, the download is direct: a single image file. When there are several, they all come bundled in a ZIP, with individual download links also available for anyone who only wants some of them. Conversion happens serially, one page at a time, yielding control back to the browser between pages so it stays responsive, with a progress bar showing how many pages have been rendered so far — and you can cancel at any point.

What this tool doesn't do

It doesn't recognize or extract the text on the pages — this isn't OCR: the result is only the visual appearance of each page, not searchable and with no selectable text. It doesn't edit the original PDF's content — no page is altered, only drawn as an image. It doesn't improve the quality of the source document: if the PDF already had low-resolution text or images, converting at a higher resolution doesn't recover detail that was never there. And it doesn't remove a password from a protected PDF, or bypass that kind of restriction.
