How to Convert PDF to JPG (Free, Every Page as an Image)
Turn every PDF page into a JPG image for sharing, socials or previews — free, no sign-up. What 150 DPI means, and when PNG keeps text sharper.
A PDF is great for printing and terrible for everything social: you can't paste it into an Instagram post, drop it inline in a chat, or use it as a thumbnail. The fix is to render each page as an image. Here's how to do it free, plus the two decisions that actually matter — resolution (DPI) and format (JPG vs PNG).
The typical jobs: a slide deck that needs to become a carousel post, a flyer going into a WhatsApp group where a PDF shows as a gray attachment but an image shows instantly, a menu or price list for a website, a portfolio page for a marketplace listing that only accepts images, or simply a preview thumbnail for a download link. In every one of these, the receiving platform speaks JPG and shrugs at PDF — so you meet it halfway.
How to convert — step by step
Open the tool
Go to pdfty.com/tools/pdf-to-jpg. Free up to 20 MB and 50 pages, no account.
Drop your PDF
Drag the file in. Upload is over HTTPS; the file is auto-deleted after 1 hour.
Conversion runs automatically
No settings to fiddle with — each page is rendered to a JPG at 150 DPI. A 20-page file takes a few seconds.
Download the ZIP
You get one ZIP containing page_001.jpg, page_002.jpg, … — already numbered in page order.
Unzip and use
Post, paste, embed. Every page is a normal JPG any app understands.
DPI and quality: what actually matters
DPI (dots per inch) decides how many pixels each page gets. An A4 page at 150 DPI becomes roughly a 1240 × 1754 px image — more than enough for screens, chat apps, social posts and web page previews, which is exactly what pdfty renders at.
As a rule of thumb:
| DPI | A4 page becomes | Good for |
|---|---|---|
| 72–96 | ~595–794 px wide | Tiny thumbnails only |
| 150 | ~1240 px wide | Screens, socials, chat, previews |
| 300 | ~2480 px wide | Print, zoomable detail |
pdfty's 150 DPI is the sweet spot for sharing. If you specifically need print-resolution 300 DPI renders, use the CLI route below — the online tool doesn't expose a DPI picker.
JPEG compression is the second factor. JPG shrinks files by discarding detail the eye mostly misses — perfect for photos and scans, less kind to razor-sharp black-on-white text, where you may notice slight halos around letters if you zoom in. At normal viewing size it's rarely visible.
JPG or PNG? Honest answer
| Format | Strengths | Weaknesses |
|---|---|---|
| JPG | Small files, universal, great for photos/scans | Lossy — faint artifacts around fine text, no transparency |
| PNG | Pixel-perfect text, lossless, transparency | Files 2–5× larger for photographic pages |
Pick JPG when pages are photographic (scans, brochures, image-heavy slides) or when upload size matters. Pick PDF to PNG when pages are mostly text, line art or diagrams and you want every letter edge perfectly clean — screenshots of contracts, documentation pages, UI mockups. Same workflow, same limits, different output format.
Free local alternatives
Mac Preview: open the PDF, File → Export, format JPEG — but it exports only the currently selected page, so a 30-page PDF means 30 exports. Fine for one page, painful for a deck.
Windows: no built-in route. The usual workaround is a screenshot (loses resolution) or installing something — at which point the browser tool is faster.
CLI (pdftoppm, free, part of Poppler): the power option —
pdftoppm -jpeg -r 150 file.pdf page converts every page locally, and
-r 300 gets you print resolution. Great for batches and privacy-
sensitive files; requires a terminal and an install
(brew install poppler / apt install poppler-utils).
LibreOffice: can export a page to an image, but like Preview it's one page at a time.
Practical gotchas
- One ZIP, even for one page. The output is always a ZIP archive —
unzip it to get the JPGs. Filenames are zero-padded
(
page_001.jpg) so they sort correctly everywhere. - White backgrounds everywhere. JPG has no transparency; any transparent regions render white. Need transparency preserved? PNG.
- The images are not searchable text. Rendering to JPG throws away the text layer. Keep the original PDF, or if you're going the other way (images → searchable), see best free OCR for PDF.
- Quality in, quality out. A blurry scan at 150 DPI is still a blurry scan. The render can't add detail the PDF doesn't have.
- Rotation carries over. The renderer honors each page's stored rotation, so the JPG matches what your viewer shows. If a scan displays sideways, fix it with Rotate before converting — straightening a JPG afterwards means re-saving and a second round of compression.
- Mind the total size. 50 image-heavy pages produce a hefty ZIP; if you then re-assemble some pages into a document, the round trip is JPG to PDF — covered in how to convert JPG to PDF.
Frequently asked questions
Can I convert just one page?
Upload the whole file and take the page you need from the ZIP, or trim first: Split or Remove pages gets you a one-page PDF, then convert that.
What resolution do I get?
150 DPI — about 1240 × 1754 px for an A4 page. Sharp on any screen and
fine for most slide-style social posts; for print-quality 300 DPI use
pdftoppm locally.
Will the text stay sharp?
Mostly, yes — at normal size JPG text looks clean. Pixel-peeping reveals slight compression softness around letters, which is inherent to JPEG. For guaranteed-crisp text, convert with PDF to PNG instead.
Does it keep the text selectable?
No. A JPG is pixels only — no text layer, no links, no selection. That's true of every PDF-to-image converter, not just this one.
Can I get the embedded photos at full resolution?
Not with this tool — it renders pages. Use Extract images, which pulls out the original embedded images untouched.
Is it really free? Any watermark?
Free: 20 MB and 50 pages per file, 10 operations a day. No watermark, no sign-up. Files are deleted after 1 hour. Pro ($9/mo) lifts the limits.
What about password-protected PDFs?
Run them through Unlock first (you need the password), then convert.
WebP or TIFF instead of JPG?
Both exist as separate tools: PDF to WebP for smaller web images, PDF to TIFF for archival and fax-style workflows. JPG remains the safest choice for anything that other people will open on unknown devices.
