Whether you need to share a PDF page on social media, embed a document in a website, or simply view a PDF as an image, converting PDF to JPG is one of the most searched file tasks online. PDFSnap lets you do it entirely free, in your browser, with no software installation — and it works equally well on your phone and computer.
Go to pdfsnap.github.io and select "PDF to JPG" from the PDF conversion tools section.
Click "Select PDF" or drag your file in. The PDF renders page-by-page in your browser — nothing is uploaded to a server.
Choose All Pages for a ZIP of every page as a JPG, or tick specific page thumbnails to export only the ones you need.
Pick from Low (72 DPI), Medium (150 DPI), or High (300 DPI). High quality is recommended for documents with fine text or detailed graphics.
Click "Convert". Single-page exports download immediately; multi-page exports arrive as a ZIP file containing numbered JPGs.
PDFSnap uses PDF.js to render your PDF entirely in your browser. Your file is never sent to our servers — making this the safest way to convert sensitive documents like contracts, ID scans, or medical records.
| Setting | DPI | Best For | Approx. Size per Page |
|---|---|---|---|
| Low | 72 DPI | Social media, web thumbnails, previews | 50–150 KB |
| Medium | 150 DPI | General sharing, email attachments | 200–500 KB |
| High | 300 DPI | Printing, archiving, detailed documents | 1–3 MB |
For most sharing purposes, Medium (150 DPI) is the sweet spot — text remains crisp and readable while file sizes stay manageable for email and messaging apps.
Converting a 20-page PDF produces 20 separate JPG files. PDFSnap packages them automatically into a single ZIP download labelled page-1.jpg, page-2.jpg, etc.
On Windows, right-click the ZIP and select "Extract All". On Mac, double-click to unzip. On mobile, use your device's Files app to open the ZIP and extract the images.

DPI controls the resolution of the JPG images produced from your PDF pages. 72 DPI produces screen-resolution images — readable but pixelated when zoomed. Smallest file sizes. Use for preview thumbnails or social media images displayed small. 150 DPI is the practical sweet spot for most digital uses — sharp on any screen at typical display sizes, manageable file sizes. Right for sharing PDF pages via messaging apps, email, or social media at full viewing size. 300 DPI produces print-quality output — sharp even when zoomed to 200% on screen and reproduces well in print. Files are much larger. Use for pages you plan to print, include in presentations at full size, or use as masters for further editing.
When converting a PDF with many pages, the output is a set of numbered JPG files — one per page — downloaded as a ZIP archive. Extract the ZIP to find your individual page images, named sequentially. For large PDFs (50+ pages), conversion takes a moment longer but processes server-side so you do not need to keep a local app running. If you only need specific pages, use PDFSnap's page extraction tool first to pull out the pages you need, then convert that smaller PDF to JPG. This is faster than converting all pages and deleting the ones you do not need.
A few problems come up regularly when converting PDFs to images. Here is how to resolve each one.
Converted images are blurry: The DPI setting is too low. Increase from 72 to 150 or 300 DPI and reconvert. Text requires at least 150 DPI to appear sharp; fine print and small footnotes need 300 DPI.
Images are much larger than expected: High DPI settings produce large files. At 300 DPI, an A4 page converts to a 2480×3508 pixel image — approximately 2–4 MB as JPEG at quality 85. If you need smaller files, either reduce DPI (150 DPI produces a 1240×1754 image, one quarter the file size) or compress the JPGs after conversion using PDFSnap's image compression tool.
Colours look different in the JPG compared to the PDF: Some PDFs use CMYK colour values designed for print. Screen image formats use RGB. Conversion between these colour spaces can cause colour shifts, particularly with reds, oranges, and certain blues. If accurate colour reproduction is important, check whether the source PDF was intended for print (CMYK) and use a colour-managed conversion tool if so. For most document-type PDFs (not designed for commercial print), this is not an issue.
Only part of the page appears in the output: Some PDFs have unusual page sizes or crop boxes that cause converters to output only the visible crop area. Try opening the PDF in a browser, zooming to fit the page, and taking a screenshot as an alternative approach for the affected page.
