PDF to PNG vs. PDF to JPG: When to Use Each
When converting PDF pages to images, you have two main choices: PNG and JPEG. Understanding the difference helps you choose the right format.
Choose PNG when:
- You need the highest possible image quality with no compression artifacts
- Your PDF contains text, screenshots, diagrams, or graphics with sharp edges and text
- You need transparency (PDFs with white backgrounds can be exported as transparent PNGs)
- You plan to further edit the image and need lossless quality
- You are creating website assets or graphics that need crisp edges
Choose JPEG when:
- Your PDF contains primarily photographs
- Smaller file size is a priority
- The image will only be viewed on screen or in print (not further edited)
- You are sharing many pages and need to keep file sizes manageable
Our [PDF to JPG](/pdf-to-jpg) guide covers the JPEG workflow in detail. This guide focuses on PNG conversion.
Step-by-Step PDF to PNG Conversion
Step 1: Upload Your PDF
Go to our [PDF to PNG](/pdf-to-png) tool. Upload your PDF file by dragging it into the browser window or clicking to browse your files.
Step 2: Select Pages to Convert
By default, the tool converts all pages. For large PDFs, you can specify a page range (e.g., pages 1–10) or select individual pages to convert. For extracting just one page, our [Extract Pages](/extract-pages) tool first pulls out the page as a single-page PDF, which you then convert.
Step 3: Choose Resolution
Resolution determines the sharpness of the output PNG:
- 72 PPI — Screen resolution, smallest file size, suitable for digital display
- 150 PPI — Good balance of quality and size for most web uses
- 300 PPI — High-resolution for printing, professional quality
- 600 PPI — Archival quality, maximum detail
For web use, 150–300 PPI is usually sufficient. For print, 300 PPI is the standard. Higher resolution produces sharper images but significantly larger file sizes.
Step 4: Download Your PNG Files
After conversion, download each page as a separate PNG file, or download all pages as a ZIP archive. PNG files from PDF conversion can be very large (1–10MB per page at high resolution), so ZIP downloading is convenient for multi-page PDFs.
Why PNG is Ideal for Text-Heavy PDFs
JPEG compression is lossy — it slightly degrades sharp edges and fine details, which creates visible artifacts (blurring, block patterns) around text characters. PNG compression is lossless, preserving every pixel exactly. This makes PNG the superior choice for PDFs containing:
- Technical documents — Schematics, code listings, engineering drawings
- Financial reports — Tables with precise numbers where blurring could change meaning
- Certificates and legal documents — Official documents where text clarity is paramount
- Presentations — Slide content with text, charts, and graphics
- Screenshots — Computer interface captures where crisp text matters
Using PNG for Website and Design Work
Social Media Graphics
Many social platforms (LinkedIn, Twitter, Pinterest) prefer PNG over JPEG for graphics and infographics because PNG handles text and mixed content better. Convert your PDF slides or infographics to PNG for social media sharing.
WordPress and Website Images
When adding PDF content to a website, PNG images from PDF conversion display sharply on high-DPI (Retina) screens. WebP conversion from PNG using [Convert Image](/convert-image) further reduces file size while maintaining quality.
Open Graph Images
Social media preview images (og:image) should be exactly 1200×630 pixels for optimal display. Convert your PDF slide or cover page to PNG, then resize to these dimensions with [Resize Image](/resize-image).
Printable Certificates and Documents
If you need to print a PDF in a context where your PDF viewer isn't available, converting to high-resolution PNG ensures exactly what you see is what gets printed.
Transparency in PDF to PNG Conversion
Most PDFs have white page backgrounds. When converting to PNG, you can choose to:
- Keep white background — Standard conversion with white backgrounds
- Transparent background — Removes the white page background, creating a true transparent PNG
Transparent background conversion is useful when your PDF has design elements (logos, infographics, slides) that you want to place over different colored backgrounds in other applications. JPEGs cannot produce transparent images — this is a PNG-exclusive feature.
Optimize PNG File Size After Conversion
High-resolution PNG files from PDF conversion can be large. To reduce file size while maintaining quality:
Resize first — If you only need the image at 800px wide, use [Resize Image](/resize-image) to scale it down before sharing
Compress the PNG — Use [Compress Image](/compress-img) with lossless PNG compression to reduce file size without any quality loss
Convert to WebP — WebP lossless is 25–35% smaller than equivalent PNG, supported by all modern browsers
Frequently Asked Questions
Why are my converted PNG files very large?
PNG is lossless, so file sizes are naturally larger than JPEG. A high-resolution PDF page at 300 PPI can produce 2–8MB PNG files. Use [Compress Image](/compress-img) or convert to WebP for smaller sizes.
