Quick FAQs
Do I need to install software to use FullConvert?
No. FullConvert is a browser-based toolkit. You can convert images, compress files, generate QR codes, format JSON, and use many utility tools without installing desktop software.
Are my files uploaded to a server?
Most image, PDF, QR, and developer tools process data directly in your browser, so files stay on your device. Tools that require server-side processing, such as some downloader workflows, clearly indicate this before you continue.
Is FullConvert free to use?
Core converter, compression, PDF, SVG, QR, and developer tools are free to use. Some usage controls may apply to keep the service stable, and the site is supported by non-intrusive advertising.
Can I use FullConvert on my phone or tablet?
Yes. All tools are responsive and optimized for mobile, tablet, and desktop screens. The same browser-first processing works across devices.
What file formats and workflows does FullConvert support?
FullConvert supports popular image formats such as PNG, JPG, WebP, HEIC, SVG, and GIF; PDF workflows; video and GIF tools; QR generators; text utilities; and developer tools such as JSON formatting, Base64, JWT decoding, hashes, regex, and timestamps.
How is FullConvert different from other online file converters?
Many online converters upload files to remote servers. FullConvert prioritizes browser-first processing whenever possible, which improves privacy for common image, document, SVG, QR, and developer workflows.
