PDF to JPG Converter
Drop in a PDF, choose a resolution and click “Convert to images” – every page becomes a JPG or PNG that you can save one by one or all together as a ZIP. The conversion runs entirely in your browser; your PDF is never uploaded.
How it is calculated
You need a PDF page as an image more often than you might think: as a preview for a website or a social media post, to paste into a presentation or a Word document, to send via a messenger app or to upload to a portal that only accepts JPG or PNG. This tool draws every selected page with pdf.js – the PDF engine Firefox uses to display PDFs – right in your browser and saves it as an image.
How it works
- Drop in or choose a PDF. Once it is open you see the first page as a preview and the page count.
- Pick a format: JPG for small files (scans, photos), PNG for lossless, razor-sharp text and graphics.
- Pick a resolution: 150 dpi is enough for screens and email, 300 dpi for printing and zooming in.
- Optionally enter pages, e.g. “1-3, 5”. Empty means all pages.
- Click “Convert to images” and download each image separately or all of them as a ZIP.
Which resolution should I choose?
PDF measures in points: 72 points make one inch. At 72 dpi one point becomes one pixel, at 150 dpi just over two pixels. An A4 page therefore gives you (US Letter is slightly wider and shorter):
- 72 dpi: 595 × 842 pixels – a small preview only.
- 150 dpi: 1,240 × 1,754 pixels – easy to read on screen, JPG usually 150–500 KB.
- 300 dpi: 2,480 × 3,508 pixels – print quality, JPG often 0.5–2 MB per page.
The JPG quality (default 90%) controls compression: below about 70% you start to see fine artefacts around text. To shrink the images further afterwards, use Compress image.
Limits
- Very large pages (posters, blueprints) are limited to 16.7 megapixels per image, because Safari on iPhone and iPad cannot render more. The tool tells you when a page was scaled down for this reason.
- Up to 200 MB per PDF and up to 300 pages per run. All images stay in memory until you download them – many pages at 300 dpi can push an older phone to its limit.
- Form fields and comments are drawn the way they are stored in the PDF; filled-in values only appear if the PDF includes their appearance. Interactive XFA forms are not supported.
- Password-protected PDFs open with their password. Without it, nothing works – the tool does not crack protection.
- Text can no longer be selected in the image. If you need the text, Image to text recognises it again.
pdf.js is loaded the first time
As soon as you choose a PDF, your browser loads the PDF engine once (about 0.5 MB compressed) from this server; for scans with JPEG 2000 or JBIG2 images and for fonts that are not embedded, small extra files are added when needed. No third-party content delivery network is contacted.
Privacy
Your PDF never leaves your device: opening, rendering and creating the images all happen in your browser, and a password is only used locally. Once you close the tab, nothing is stored. You can also go the other way: Images to PDF turns JPGs back into a PDF, and Split PDF extracts single pages as a PDF.
Frequently asked questions
How do I convert a PDF to JPG?
Drop your PDF in here, choose “JPG” and a resolution (150 dpi for screens, 300 dpi for print) and click “Convert to images”. Every page becomes its own JPG; download them all at once as a ZIP.
Is my PDF uploaded?
No. The conversion runs entirely in your browser. Only the pdf.js engine is loaded from this server – your file and the images stay on your device.
Can I save just one page of a PDF as a JPG?
Yes. Enter the page number under “Pages”, e.g. “3”, or several ranges such as “1-3, 7”. Empty means all pages.
How do I get high quality images?
Choose 300 dpi and PNG, or JPG with at least 90% quality, for text and graphics. For email and screens 150 dpi is enough – the files are then about four times smaller.
JPG or PNG – which is better?
JPG creates much smaller files and suits scans and photos. PNG is lossless: text, lines and charts stay razor-sharp, but the files are larger.
Does it work with a password-protected PDF?
Yes, if you know the password. The tool asks for it as soon as the PDF is protected. The password is only used locally to open the file and is not stored.
Can I convert PDF to JPG on iPhone or Android?
Yes, in Safari, Chrome and Firefox. On iPhone the images land in the Downloads folder of the Files app, from where you can save them to Photos. For many pages at 300 dpi, convert in several runs.
How do I turn JPGs back into a PDF?
With Images to PDF: choose the images, set the order and save the PDF – also without uploading anything.
