Convert a PDF to JPG

JPG is the format almost anything will accept, and the smaller of the two. This opens with JPG already selected.

PDF files up to 25.00 MB, up to 50 pages at a time.

Your PDF is read in this browser tab. It is not uploaded.

When you need this

A PDF is awkward in all the places an image is easy. Converting the pages to JPG is usually about getting a document into somewhere that will not take a PDF at all:

  • upload forms that accept only .jpg or .png — visa applications and job portals are notorious for it;
  • posting a page to social media, or into a chat that collapses PDFs into a grey attachment nobody opens;
  • dropping a page into a slide deck or a document as a picture;
  • sending a preview of one page without attaching all forty;
  • printing from a device that will not render PDFs properly.

What you give up

Converting is not lossless, and it is worth knowing exactly what changes before you replace the original:

  • The text stops being text. It becomes pixels, so it can no longer be selected, searched, copied or read aloud by a screen reader. This is the big one, and it is why you should keep the PDF rather than throwing it away.
  • Links and form fields stop working. They are drawn into the picture but do nothing.
  • JPG compression is lossy. On text-heavy pages it can soften the letters a little. High quality settings keep this invisible at normal viewing size.

JPG or PNG for a document?

It depends what is on the page, and the honest answer is often PNG. A page of text, a table, an invoice or a diagram is exactly the kind of flat, high-contrast image PNG handles best, and where JPG’s artefacts are most visible. A page that is mostly a scanned photograph is the other way round: JPG will be several times smaller for no visible difference.

If sharp text matters more than file size, use PDF to PNG. If you are not sure, try one page each way and compare.

Common questions

Does my PDF get uploaded to convert it?
Not here. Most PDF-to-JPG sites send your document to a server, run the conversion there and delete it afterwards — which asks you to trust both the promise and the company keeping it. Celveri renders the pages inside your own browser using pdf.js, the engine Firefox uses to display PDFs. There is no upload endpoint to send it to.
How many JPGs will I get?
One per page. A ten-page PDF gives ten JPG files, named after the document and numbered in order — report-page-01.jpg, report-page-02.jpg and so on, zero-padded so they sort correctly in a folder. If you only want one page, set a range such as 3 and you will get just that page.
Why does my text look slightly fuzzy?
That is JPG doing what JPG does. It was designed for photographs, and it saves space by approximating areas of the image — which shows up as faint haloes around the sharp black-on-white edges of letters. Two fixes: raise the quality slider towards 100, or use PDF to PNG instead, which stores every pixel exactly and keeps text crisp.
What resolution do I need?
For viewing on a screen or attaching to an email, 150 DPI is plenty and is the default. For printing, or if someone needs to read small print in the result, choose 300 DPI. Going higher than 300 rarely helps and makes the files much larger — doubling the DPI quadruples the pixel count.
Can I turn the JPGs back into a PDF?
Celveri cannot do that yet. Converting a page to JPG and back would in any case not return you to the original: the text has become pixels along the way, and nothing can turn them back into selectable words.
The file is too big to email. What now?
Lower the resolution to 72 DPI, or drop the quality slider — either will shrink the result substantially. If you need to hit a specific limit, the compress-to-100 KB tool takes the JPGs this produces and brings them under a target size.
