How to Convert PDF to Image: Free Online PDF to PNG/JPEG Tool

Need to extract pages from a PDF as images? This PDF to Image Converter turns PDF pages into high-quality PNG or JPEG images directly in your browser. Select specific pages, choose your output format, and adjust the resolution — no upload to any server, no account required.

What Is a PDF to Image Converter?

A PDF to image converter renders each page of a PDF document as a standalone image file. Instead of needing a PDF viewer, you get standard image files (PNG or JPEG) that can be inserted into presentations, shared on social media, embedded in websites, or edited in any image editor.

This tool uses Mozilla's PDF.js library to render pages entirely in your browser. Your PDF never leaves your device.

How to Convert a PDF to Images

Step 1: Upload Your PDF

Click the upload area or drag and drop a PDF file. The tool reads the file and displays the page count.

• Maximum file size: 50 MB
• Supported: Standard PDF files (PDF 1.0 through 2.0)
• Not supported: Password-protected or encrypted PDFs

After uploading, you'll see the filename, file size, and total page count. You can click Change to swap the file or the trash icon to remove it.

Step 2: Configure Settings

Adjust the output using three settings:

Output Format

Format	File Type	Compression	Best For
PNG	.png	Lossless	Text documents, screenshots, graphics — sharp edges, no artifacts
JPEG	.jpg	Lossy (92% quality)	Photos, scanned documents — smaller file size

When to choose PNG: You need pixel-perfect accuracy, the PDF contains text or line art, or you plan to edit the image further.

When to choose JPEG: File size matters more than perfect sharpness, the PDF contains photos, or the images are for web/email use.

Quality / DPI

DPI (dots per inch) controls the resolution of the output images. Higher DPI means more pixels, more detail, and larger file sizes.

Setting	DPI	Pixels per A4 Page	Best For
Standard	72	595 × 842	Quick preview, screen viewing
High	144	1190 × 1684	General use, presentations, web
Ultra	216	1785 × 2526	Printing, archiving, zoom-heavy use

Recommendation: High (144 DPI) is the best balance for most uses. Use Standard for quick previews or when file size is critical. Use Ultra only when you need print-quality output or need to zoom into fine details.

Page Range

Control which pages to convert:

• all — convert every page in the PDF (default)
• 1-5 — convert pages 1 through 5
• 1, 3, 7 — convert only pages 1, 3, and 7
• 1-3, 8, 12-15 — combine ranges and individual pages

Page numbers that exceed the document's page count are silently ignored.

Step 3: Convert

Click the Convert Pages button. A progress bar shows the conversion status as each page is rendered.

Step 4: Download

After conversion, you'll see a gallery of all converted pages with thumbnails. Each image shows the page number and pixel dimensions.

• Download individual pages — click the download icon on any page thumbnail
• Download All — downloads every converted page as separate image files

Files are named automatically: {original-filename}-page-{number}.png (or .jpg).

Understanding DPI and Image Quality

DPI determines how many pixels are used to represent each inch of the PDF page. Since PDF pages have fixed physical dimensions (A4 is 210 × 297 mm), higher DPI means more pixels in the output image.

How DPI Affects Output

For a standard A4 page:

DPI	Image Width	Image Height	Approx. File Size (PNG)
72	595 px	842 px	200–500 KB
144	1190 px	1684 px	500 KB – 2 MB
216	1785 px	2526 px	1–5 MB

File sizes vary based on page content. Text-heavy pages produce smaller PNGs (compresses well) and larger JPEGs. Photo-heavy pages are the opposite.

Choosing the Right DPI

• 72 DPI — sufficient for screen viewing at 100% zoom. Text is readable but may look slightly soft. Good for quick shares and previews.
• 144 DPI — sharp on all screens including high-DPI (Retina) displays. Text is crisp, graphics are detailed. This is the sweet spot for most uses.
• 216 DPI — overkill for screen use but valuable for printing. If you need to print the images or zoom into fine print, use this setting.

Tips for Better Conversions

1. Use PNG for text-heavy PDFs. JPEG compression creates visible artifacts around sharp text edges. PNG preserves every pixel exactly.

2. Use JPEG for photo-heavy PDFs. If the PDF is mostly photographs or scanned images, JPEG produces much smaller files with negligible visual difference.

3. Convert only the pages you need. If you only need pages 1–3 from a 50-page PDF, use the page range field. This saves processing time and gives you fewer files to manage.

4. Start with High DPI. 144 DPI is the right choice for most purposes. Only increase to Ultra if the result isn't sharp enough, or decrease to Standard if you need the smallest possible files.

5. Check the preview before downloading. The gallery shows thumbnails of every converted page. Zoom in on a thumbnail to verify text readability and image clarity before downloading.

Frequently Asked Questions

Is my PDF processed on a server?

No. The entire conversion happens in your browser using Mozilla's open-source PDF.js library. Your PDF file is read directly from your device, rendered to a canvas element, and exported as images — all locally. Nothing is uploaded.

Can I convert password-protected PDFs?

No. Password-protected or encrypted PDFs cannot be opened by the browser-based renderer. You'll need to unlock the PDF first using its password in a PDF viewer, then save an unprotected copy.

Why are some pages blank or incorrectly rendered?

Some PDFs use advanced features (embedded fonts, complex vector graphics, interactive forms) that may not render perfectly in the browser-based engine. If a page appears incorrect:

• Try a different DPI setting
• Open the PDF in a desktop PDF viewer and use its export function as a fallback

Can I convert a PDF to a single image with all pages?

No. Each PDF page is converted to a separate image. This tool produces one image per page. To combine them into a single tall image, you would need to stitch the resulting images together in an image editor.

What's the maximum PDF size?

The tool accepts PDFs up to 50 MB. For very large PDFs with many pages, conversion may take longer as each page must be rendered individually in the browser.

Will the images match the PDF exactly?

The browser-based renderer produces high-fidelity output for most PDFs. Standard text, images, and vector graphics render accurately. Fonts are substituted if the exact font isn't available in the browser, which can cause minor spacing differences in rare cases.

PNG or JPEG — which should I choose?

Criteria	Choose PNG	Choose JPEG
Text sharpness	Pixel-perfect	Slight artifacts
File size	Larger	3–5x smaller
Transparency	Supported	Not supported
Photo quality	Same as JPEG	Same as PNG
Editing further	Better (lossless)	Loses quality on re-save

Rule of thumb: PNG for documents, JPEG for photos.

How long does conversion take?

Conversion time depends on the number of pages, the DPI setting, and your device's processing power. Typical times:

• 1–5 pages at High DPI: 1–3 seconds
• 20 pages at High DPI: 5–10 seconds
• 50 pages at Ultra DPI: 15–30 seconds

A progress bar shows the conversion percentage in real time.

Can I batch-download all images at once?

The Download All button downloads each converted image as a separate file. Your browser may ask permission to download multiple files. The images are saved with sequential filenames for easy organization.

When to Use a PDF to Image Converter

• Insert PDF pages into presentations — export specific pages as images for PowerPoint, Google Slides, or Keynote
• Share on social media — post individual pages from a PDF as images on platforms that don't support PDF uploads
• Embed in websites or documents — use PDF pages as images in web pages, Word documents, or email newsletters
• Create thumbnails — generate preview images of PDF pages for file managers or document galleries
• Edit PDF content visually — export a page as an image, annotate or crop it in an image editor, then use the result
• Archive documents as images — convert PDF pages to a universal image format for long-term storage
