Guides & How-To Articles
Learn how to make the most of our tools with these helpful guides
Most people don't understand how privacy-first tools work, and that's completely normal. Traditional online tools require uploading your files to servers for processing, but our approach is fundamentally different.
All PureXio tools process your files entirely in your browser using JavaScript. Your files never leave your device - no uploads, no servers, no data storage. This is called client-side processing.
Your files stay completely private and secure. No one can access your sensitive documents, images, or data. This is especially important for business documents, personal photos, or any content you wouldn't want stored on someone else's servers.
This concept is hard to grasp because most online tools work differently. When you see 'online tool,' most people assume it means 'server-based tool.' Privacy-first tools challenge this assumption by doing everything locally in your browser.
Since we process everything in your browser without any backend services, there are some limitations to what we can offer. This privacy-first approach means we cannot provide tools that require intensive computational resources.
What are the limitations?
- No AI-powered features that require massive computational resources
- No real-time collaboration features that need server synchronization
- No cloud storage or file sharing capabilities
- No tools that require accessing external databases or APIs
- Limited processing speed for very large files due to browser constraints
Thankfully, many of the tools people need most are lightweight and work perfectly with our privacy-first solution. We can provide excellent PDF tools, image processing, text formatting, and developer utilities without ever compromising your privacy.
PDF Tools Guides
Best Practices
- Use our PDF Compress tool to reduce file size while maintaining quality
- Remove unnecessary images or compress them before adding to PDFs
- Use appropriate compression levels: Fast for quick reductions, Maximum for smallest file size
- Check the preview to ensure quality meets your needs before downloading
- For scanned documents, consider using OCR tools first to make text searchable
Step-by-Step Process
- Open our PDF Merge tool and select all PDF files you want to combine
- Arrange files in the desired order using drag and drop
- Click 'Merge PDFs' to combine all files into one document
- Download your merged PDF file
- All processing happens in your browser - your files never leave your device
Image Tools Guides
Format Comparison
- PNG: Best for images with transparency, logos, and graphics with sharp edges. Lossless compression.
- JPG: Ideal for photographs and images with many colors. Smaller file sizes with lossy compression.
- WebP: Modern format offering both lossy and lossless compression. Best compression ratios but limited browser support.
- Use our Image Convert tool to transform images between formats while optimizing file size
Compression Types
- Lossless compression: Reduces file size without quality loss. Best for graphics, logos, and images requiring perfect quality.
- Lossy compression: Significantly reduces file size by removing some image data. Best for photographs and web images.
- Use our Image Compress tool to find the perfect balance between file size and quality
- For web use, aim for 80-85% quality to maintain visual appeal while reducing load times
- Always preview compressed images before using them in production
Developer Tools Guides
Best Practices
- Use our JSON Formatter to beautify and validate your JSON data
- Always validate JSON before using it in production code
- Use consistent indentation (2 or 4 spaces) for readability
- Escape special characters properly in string values
- Keep JSON structures flat when possible for better performance
- Use our JSON to CSV converter when you need to work with spreadsheet data
When to Use Each Encoding
- Base64 Encoding: Use for embedding binary data in JSON, XML, or email. Also useful for data URIs in HTML/CSS.
- URL Encoding: Essential for passing data in URLs, form submissions, and API requests. Ensures special characters are properly handled.
- HTML Entity Encoding: Use when displaying user-generated content in HTML to prevent XSS attacks
- Hex Encoding: Useful for representing binary data in a human-readable hexadecimal format
- Use our encoding tools to quickly convert between formats without manual work
General Tips & Best Practices
All PureXio tools process your files entirely in your browser. This means:
- Your files never leave your device - complete privacy and security
- No server uploads means faster processing and no bandwidth limits
- Your sensitive documents remain completely private
- No account required - just use the tools directly
- Works offline once the page is loaded
Optimization Tips
- Compress images before uploading to reduce page load times
- Use appropriate image formats: JPG for photos, PNG for graphics with transparency
- Resize images to the exact dimensions needed rather than scaling in CSS
- Compress PDFs to reduce download times for your users
- Remove unnecessary metadata from files to reduce size
- Use our batch processing tools when working with multiple files
Frequently Asked Questions
General Questions
Yes! All tools on PureXio are 100% free with no hidden costs, subscriptions, or usage limits. We believe in providing accessible tools for everyone.
No account is needed. Simply visit any tool page and start using it immediately. We don't require registration or sign-up.
The only limit is your browser's memory capacity. For best performance, we recommend keeping files under 50MB for PDF tools and 20MB for image tools.
Privacy & Security
No. All processing happens directly in your browser using JavaScript. Your files never leave your device, ensuring complete privacy and security.
We only use privacy-friendly analytics to track page views. We don't track, store, or have access to any files you process. See our Privacy Policy for details.
Once a tool page is loaded, most tools work offline since all processing happens in your browser. However, you need an initial internet connection to load the page.
Technical Questions
PureXio works on all modern browsers including Chrome, Firefox, Safari, and Edge (latest 2 versions). Some features may not work on older browsers.
Processing speed depends on your device's performance and file size. Large files may take longer. Try using smaller files or a device with better specifications.
We appreciate bug reports! Please contact us through the email provided in our Imprint page with details about the issue and your browser version.
Tool-Specific Questions
Compressing reduces file size by optimizing image data while keeping the same dimensions. Resizing changes the actual pixel dimensions of the image.
Some tools support batch processing (like PDF Merge). Check the individual tool page to see if batch processing is available.
We use optimized settings that balance file size reduction with visual quality. For images, we typically use 80-85% quality for JPEGs.
