Everything you need to know about Convertly and how it works.
Yes, completely free with no hidden fees, subscriptions, or premium tiers. All features are available to everyone. Convertly is open-source and maintained by the Gegamo Team.
When you drop a file into Convertly, your browser handles the entire conversion using JavaScript and the Canvas API. The file never leaves your device. No data is sent to any server at any point during the process.
We support 50+ formats across images (PNG, JPG, WEBP, GIF, BMP, SVG, TIFF, ICO), documents (TXT, HTML, Markdown), and data files (JSON, CSV, XML, YAML, TSV). We're constantly adding more.
There's no hard limit imposed by Convertly. Since processing happens in your browser, the practical limit depends on your device's available memory. Most files up to several hundred MB work fine.
Yes! Our batch conversion feature lets you drag and drop multiple files at once. Each file is processed independently and you can download them individually or all at once as a ZIP file.
No. Zero data collection, zero tracking, zero cookies, zero analytics. We don't even have a backend server. Your privacy is absolute and non-negotiable.
Yes, for image conversions you can adjust the output quality using a slider. This is especially useful for lossy formats like JPG and WEBP where you want to balance quality vs file size.
Yes! Convertly is fully open-source under the MIT license. You can view, fork, and contribute to the codebase on GitHub. We welcome contributions from the community.
