Understanding File Formats: A Complete Guide
Learn about the different file formats we support and when to use each one for optimal results.
Document Formats Explained
DOCX (Microsoft Word Document) is the most popular editable document format. It supports rich text formatting, images, tables, headers, footers, and collaborative features like track changes and comments. Use DOCX when you need to create or edit documents with formatting. Converting PDF to DOCX allows you to edit previously locked documents, while converting DOCX to PDF creates a final, uneditable version for distribution.
Plain text files (TXT) contain no formatting whatsoever, making them the most compatible format across all systems. They're perfect for code, configuration files, simple notes, and situations where you need guaranteed compatibility. HTML (HyperText Markup Language) is ideal for web content, allowing you to embed links, images, and formatting that displays in web browsers.
Image Format Selection Guide
Choosing the right image format significantly impacts file size, quality, and compatibility. JPEG (JPG) uses lossy compression, meaning it reduces file size by permanently removing some image data. This makes JPEG perfect for photographs and complex images where slight quality loss is acceptable in exchange for smaller file sizes. Use JPEG for photos you're sharing online, emailing, or posting to social media.
PNG (Portable Network Graphics) uses lossless compression and supports transparency, making it ideal for logos, graphics with text, screenshots, and any image where you need perfect quality or transparent backgrounds. While PNG files are larger than JPEGs, they preserve every pixel of the original image. Convert to PNG when you need transparency or when working with graphics that have sharp edges and text.
WEBP is a modern format developed by Google that offers superior compression compared to both JPEG and PNG while maintaining excellent quality. It supports both lossy and lossless compression plus transparency, making it versatile for web use. Convert images to WEBP to significantly reduce your website's load times and bandwidth usage. However, note that older browsers may not support WEBP, so always have fallback formats available.
SVG (Scalable Vector Graphics) is fundamentally different from raster formats like JPEG and PNG. Instead of storing pixels, SVG uses mathematical equations to define shapes, making it infinitely scalable without quality loss. This makes SVG perfect for logos, icons, and illustrations that need to look sharp at any size, from tiny mobile screens to billboard-sized displays.

File Conversion Tips & Best Practices
Getting the best results from file conversion requires understanding a few key principles.
Choosing the Right Format
- •For final distribution: Convert to PDF when you want recipients to see exactly what you created, regardless of their device or software.
- •For collaborative editing: Use DOCX for documents that need team input, comments, or revision tracking.
- •For web publishing: Convert images to WEBP for the best balance of quality and file size on modern websites.
- •For data exchange: CSV is the universal format for spreadsheet data across different applications and databases.
Quality Tips
- •Start with high quality: Always begin with the highest quality source file. You can't add detail that wasn't there originally.
- •Understand lossy vs lossless: JPEG uses lossy compression (removes data), while PNG uses lossless (no quality loss).
- •Preserve originals: Always keep original files before conversion in case you need to start over.
- •Avoid repeated conversions: Each lossy conversion degrades quality. Convert once to your final format.
Frequently Asked Questions
Find answers to the most common questions about using Convertz.online.
Is Convertz.online safe and secure?
Yes, absolutely. All file conversions happen directly in your browser using client-side processing whenever possible. Your files never leave your device during conversion—they're not uploaded to servers or stored in any database.
For server-based conversions, files are processed immediately and automatically deleted within minutes. We don't track, analyze, or retain any of your files.
Do you store my files after conversion?
No, we never permanently store your files. For client-side conversions, files exist only in your device's memory and disappear when you close the page.
For server-processed conversions, files are held in temporary memory only during conversion and are permanently deleted immediately after. We have no database for user files.
What's the maximum file size?
We don't impose arbitrary file size limits. However, very large files (over 100MB) may take longer to process and could be limited by your browser's capabilities.
For optimal performance, we recommend files under 50MB. Processing time depends on your device's performance.
Are there conversion limits?
No, there are absolutely no limits. You can convert as many files as you need with no daily limits, monthly quotas, or conversion caps. Our service is completely free with unlimited use.
What formats do you support?
We support over 50 different file formats. Documents include PDF, DOCX, TXT, RTF, ODT, MD, HTML, and PDF/A. Images include JPG, PNG, WEBP, GIF, BMP, ICO, TIFF, and SVG.
We also support spreadsheets (XLSX, CSV, ODS), presentations (PPTX, ODP), archives (ZIP, GZ), and e-books (EPUB, MOBI, AZW3, FB2).
Do I need to create an account?
No account or registration is required. Simply visit the site, upload your files, select your format, and convert. No email verification, no password creation, no personal information required. This approach respects your privacy and saves your time.
How long does conversion take?
Most conversions complete in 5-15 seconds. Complex conversions like PDF to editable formats may take 30-60 seconds.
Processing time depends on file size, conversion complexity, internet speed, and your device's processing power.
Will conversion affect quality?
Quality depends on the formats involved. Lossless to lossless maintains perfect quality. Lossy to lossless preserves existing quality but can't recover lost detail. We use high-quality conversion libraries to ensure the best possible output.
