How to Use
Step 1: Choose Your Settings
Before uploading, configure your output preferences:
Output Format Selection
PNG (Recommended for Documents)
- Lossless compression - no quality loss
- Best for: Text documents, diagrams, charts
- Larger file sizes
- Perfect quality preservation
- Supports transparency
JPEG (Recommended for Photos)
- Lossy compression - smaller file sizes
- Best for: Photo-heavy PDFs, scans, images
- Quality slider available (50% to 100%)
- Smaller files for easier sharing
- No transparency support
Quality Control (JPEG Only)
When JPEG is selected, use the quality slider:
- 50-70%: Smaller files, visible compression artifacts
- 75-85%: Good balance of quality and size
- 90-95%: High quality, minimal compression (recommended)
- 100%: Maximum quality, larger files
Tip: Start with 95% quality for most documents. Reduce if file size is a concern.
Step 2: Upload Your PDF
- Click the upload area or drag-and-drop a PDF file
- Select a PDF file from your device
- Wait for the conversion process to begin
- Watch the progress bar as each page is processed
Supported Files:
- Any valid PDF file
- Single or multi-page PDFs
- Password-protected PDFs must be unlocked first

Step 3: Monitor Conversion Progress
During conversion, you'll see:
- Loading Spinner: Animated indicator showing active processing
- Progress Text: "Processing page X of Y"
- Progress Bar: Visual representation of completion percentage
- Page Counter: Real-time update of current page
Note: Conversion speed depends on:

Step 4: Review Converted Images
Once conversion completes, you'll see:

Tips & Best Practices
Choosing the Right Format
✅ Use PNG for:
- Text-heavy documents (contracts, forms, letters)
- Diagrams and charts with sharp lines
- Screenshots and interface mockups
- Documents requiring transparency
- When quality is more important than file size
✅ Use JPEG for:
- Photo-heavy PDFs (photo albums, portfolios)
- Scanned documents with image content
- PDFs with full-page images
- When file size is a concern
- Content for web or email sharing
Optimizing Quality vs. Size
For Maximum Quality:
- Choose PNG format
- Accept larger file sizes
- Best for archival and print
For Balanced Output:
- Choose JPEG format
- Set quality to 90-95%
- Good for most use cases
For Minimum File Size:
- Choose JPEG format
- Set quality to 70-80%
- Test to ensure acceptable quality
- Best for web sharing
Batch Processing Tips
For Large PDFs (50+ pages):
- Close other browser tabs to free memory
- Process during low-activity periods
- Be patient - conversion takes time
- Don't close the browser tab during processing
For Multiple PDFs:
- Convert one PDF at a time
- Download all images before converting next PDF
- Organize downloaded files by source PDF
- Consider renaming files for better organization
Troubleshooting Common Issues
Conversion is Slow
- Close unnecessary browser tabs
- Close other applications to free RAM
- Try a smaller batch of pages
- Update your browser to the latest version
Images Look Blurry
- This shouldn't happen with 2x rendering
- Check source PDF quality
- Try PNG format instead of JPEG
- Ensure JPEG quality is set to 90%+
Browser Becomes Unresponsive
- PDF may be too large for available memory
- Try converting fewer pages at a time
- Close other tabs and applications
- Restart browser and try again
Frequently Asked Questions
General Questions
Q: Is there a page limit?
A: There's no artificial limit, but browser memory constraints may limit very large PDFs. Most browsers can handle 100-200 pages comfortably.
Q: Can I convert password-protected PDFs?
A: No, password-protected PDFs must be unlocked first. Use a PDF password remover tool before conversion.
Q: Will the conversion preserve colors?
A: Yes, colors are preserved accurately. RGB color space is used for all output images.
Q: Can I convert specific pages instead of all pages?
A: Currently, the tool converts all pages. You can download only the specific pages you need from the results.
Q: What happens to hyperlinks and annotations?
A: Hyperlinks and annotations are rendered visually but are not interactive in the output images (as images don't support interactivity).
Technical Questions
Q: Why does conversion take so long?
A: Each page is rendered individually at high resolution (2x scale). Complex pages with many images take longer to process.
Q: Can I convert PDFs offline?
A: Yes, once the page is loaded, conversion works completely offline as everything runs in your browser.
Q: Does this work on mobile devices?
A: Yes, but performance may be slower and memory limits may restrict the size of PDFs you can convert.
Q: What's the maximum file size?
A: There's no hard limit, but practical limits are around 50-100 MB depending on your device's available memory.
Q: Why is PNG so much larger than JPEG?
A: PNG uses lossless compression, preserving every pixel exactly. JPEG uses lossy compression, discarding some data to reduce file size.
Privacy & Security Questions
Q: Are my PDFs uploaded to a server?
A: No. All processing happens entirely in your browser. Your files never leave your device.
Q: Can I use this for confidential documents?
A: Yes, since everything is processed locally. However, always follow your organization's security policies.
Q: Is there any tracking or analytics?
A: We don't track your files or conversions. The tool respects your privacy completely.
Q: What happens to my images after I close the browser?
A: All data is immediately cleared from browser memory when you close the tab or refresh the page.
