How PDF to JPG Conversion Works
A PDF is a structured document, it contains text, fonts, vector graphics, and images arranged in layers. A JPG is a flat photograph. Converting between them is like taking a screenshot of each page: the tool renders the PDF exactly as your browser would display it, then captures that rendered output as a pixel image.
This tool uses pdf.js (Mozilla's open-source PDF renderer) to draw each page onto an invisible HTML canvas, then exports that canvas as a JPEG file. The rendering is identical to what you see when you view a PDF in Firefox or Chrome, every font, every line, every colour is faithfully reproduced.
Two settings control the output: scale determines how many pixels each page gets (higher = sharper but larger files), and JPEG quality controls compression (higher = less compression, larger files, sharper text). Getting these right is the difference between a crisp, readable image and a blurry, artefact-ridden mess.
Everything runs in your browser. Your PDF never leaves your device, no upload, no server processing, no privacy risk. That matters when you're converting contracts, financial documents, medical records, or anything you wouldn't want on a random server.
Understanding Scale, DPI, and Quality
These three concepts trip up most people. Here's how they relate:
Scale
A multiplier for the page's base resolution. A standard A4 PDF page is roughly 595×842 points. At 1× scale, you get a 595×842 pixel image. At 2×, you get 1190×1684 pixels, 4 times the pixel data, much sharper.
DPI (Dots Per Inch)
How many pixels fit in one physical inch when printed. 72 DPI is screen resolution. 150 DPI is acceptable for home printing. 300 DPI is the professional print standard. Scale × 72 ≈ output DPI.
JPEG Quality
A compression dial from 0-100%. At 100%, there's minimal compression, large file, maximum sharpness. At 50%, aggressive compression creates small files but visible blurring around text. The sweet spot is 80-92% for most uses.
| Scale | Approx DPI | A4 Page Resolution | File Size (per page) | Good For |
|---|---|---|---|---|
| 0.5× | ~36 | 298 × 421 | 20-60 KB | Thumbnails, previews only |
| 1× | ~72 | 595 × 842 | 60-200 KB | Quick sharing, messaging apps |
| 2× (recommended) | ~144 | 1190 × 1684 | 200-700 KB | Presentations, education, email |
| 3× | ~216 | 1785 × 2526 | 500 KB-2 MB | Home printing, archival, OCR |
| 4× | ~288 | 2380 × 3368 | 1-5 MB | Professional print, large format |
What this means for you: 2× scale at 85% quality is the sweet spot for most uses. It's sharp enough for presentations, clear enough for text, and small enough to email. Only go to 3× or 4× if you're printing or need to zoom into fine details.

Worked Example: Teacher Converting Course Materials
Ms. Chen teaches Year 10 Chemistry. She has a 40-page PDF textbook chapter she wants to convert to images for her Moodle course. Students will view pages on laptops and tablets.
Settings chosen: 2× scale, 85% quality, text is crisp on screens, and 40 pages at ~500 KB each totals only 20 MB.
Problem: Moodle upload limit is 50 MB total, and she also needs to upload worksheets. 20 MB for images leaves plenty of room.
Alternative considered: 3× scale would give print-quality at ~1.5 MB/page = 60 MB total, exceeds the limit. 2× is the right call for screen viewing.
| Setting | Value | Result |
|---|---|---|
| Scale | 2× | 1190 × 1684 pixels per page |
| Quality | 85% | Barely any compression artefacts |
| Pages | 40 | 40 individual JPG files |
| Total size | ~20 MB | Well within Moodle's 50 MB limit |
Pro tip: Ms. Chen names the files chem-ch5-page-01.jpg through chem-ch5-page-40.jpg so they sort correctly when uploaded. This tool outputs files in page order, so just rename the batch.
Image Format Comparison
JPEG is the default output, but it's not always the best choice. Here's a complete comparison of image formats you might use after converting from PDF.
| Format | Transparency | Compression | Text Clarity | Typical Size | Best For |
|---|---|---|---|---|---|
| JPEG (.jpg) | No | Lossy | Good at 85%+ | 100 KB-2 MB | Photos, mixed content, sharing |
| PNG (.png) | Yes | Lossless | Perfect | 500 KB-10 MB | Text-heavy pages, diagrams, screenshots |
| WebP (.webp) | Yes | Lossy or lossless | Very good | 50 KB-1 MB | Websites, blogs, anywhere file size matters |
| AVIF (.avif) | Yes | Lossy | Good | 30 KB-500 KB | Cutting-edge web; smallest files |
| TIFF (.tiff) | Yes | Lossless | Perfect | 5-50 MB | Print, archival, professional publishing |
What this means for you: For sharing and presentations, JPG is fine, it's universally supported and small. For text-heavy pages where you need razor-sharp characters, convert to PNG. For websites, WebP gives you 30-50% smaller files at the same quality.
What You Lose When Converting PDF to Image
Converting a PDF to JPG is a one-way trip. You're turning a structured document into a flat photograph. Here's exactly what doesn't survive the conversion:
| Element | Preserved? | What Happens | Alternative |
|---|---|---|---|
| Visual appearance | Yes | Pixel-perfect reproduction of what you see on screen | — |
| Selectable text | No | Text becomes pixels, can't copy, paste, or search | PDF to Word |
| Hyperlinks | No | Clickable URLs become inert blue text | Keep PDF for link-heavy docs |
| Form fields | No | Checkboxes, dropdowns, text inputs all become static images | Keep PDF for fillable forms |
| Accessibility | No | Screen readers can't read image-only content | Always provide alt text |
| Vector sharpness | Partial | Vector graphics are rasterized, can't scale infinitely anymore | Use high scale (3×+) to minimise loss |
| File size | Varies | Text-heavy PDFs get larger as images; image-heavy PDFs may get smaller | Image Compressor |
What this means for you: If you need editable text or working links, use PDF to Word instead. If you just need a visual snapshot for presentations, social media, or embedding in another document, JPG is exactly right.
Multi-Page PDF Tips
Converting a 1-page PDF is simple. A 200-page document needs a bit more thought:
Extract specific pages first
If you only need pages 5-10 from a 200-page PDF, use Split PDF to extract just those pages. Converting all 200 pages wastes time and storage when you only need 6 images.
Estimate total file size
Multiply per-page size by page count. 100 pages at 2× scale ≈ 50 MB of images. If that's too much, reduce scale to 1.5× (saves ~40%) or lower quality to 75% (saves ~20%).
Name files with zero-padded numbers
Name files as page-001.jpg, page-002.jpg, etc. Without zero-padding, "page-10.jpg" sorts before "page-2.jpg" in most file managers, annoying when you have 50+ pages.
Browser memory limits
Very large PDFs (500+ pages) at high scale (4×) can exceed browser memory. If the browser freezes, try in smaller batches: split the PDF into chunks of 50-100 pages, convert each separately.
Common Mistakes
Using 1× scale for print
1× scale gives ~72 DPI, fine for screens, terrible for printing. At 72 DPI, text looks blurry and images look pixelated. For printing, use minimum 3× scale (216 DPI), ideally 4× (288 DPI).
Setting quality below 70%
Below 70% quality, JPEG compression creates visible "ringing" artefacts around text edges, a smudgy halo effect. The file size savings from 70% to 50% are marginal, but the quality drop is dramatic.
Converting instead of sharing the PDF
If the recipient can open PDFs (they can, every device can), just send the PDF. Converting to images loses interactivity and usually increases total file size. Only convert when you specifically need images.
Not compressing afterwards
If you're uploading converted images to a website, run them through Image Compressor first. A single uncompressed page image can be 1-2 MB, that's a 3-second page load on mobile.
Forgetting about accessibility
Images of text are invisible to screen readers. If you're publishing converted pages on a website, add alt text describing the content, or provide the original PDF alongside the images.
Using JPG for diagrams and line art
JPEG compression is designed for photographs, smooth gradients. Sharp lines and solid colours get compression artefacts. For technical drawings, flowcharts, or line art, convert to PNG instead.
