Is Convertio safe?
Convertio is a well-known converter with a published deletion policy. For private files, the safer choice is a converter that never receives them.
The short answer
Convertio.co is a legitimate and widely used converter. Its terms name the operator as Convertio Limited, a company registered in Limassol, Cyprus, and its privacy page sets out how quickly files are removed. For a font, an e-book or an unusual audio format with nothing personal in it, it is a practical option.
It converts on its servers, which means uploading. Whether that is safe for you depends on the file, not the brand: a vacation photo and a scanned tax return deserve different answers.
Convertio’s stated practices
As of October 2026, per Convertio’s privacy page and terms:
- Input files are removed right after conversion.
- Converted files are deleted when you click the × next to them, or automatically after 24 hours.
- Access. The company says it does not read, look into or copy your files.
- Location. Files are kept in the European Union.
- Transport. Connections use a secure channel with HSTS enabled.
- Ads and analytics. The site uses cookies, Google Analytics and Google AdSense, and third-party advertisers may use their own tracking.
Putting that in context
Deleting inputs immediately and outputs within a day is a reasonable policy for a free converter, and keeping data in the EU brings GDPR protections. What the policy cannot remove is the period in which the converted copy exists on its servers, or the need to take deletion on trust.
The advertising matters for a different reason. On ad-supported file sites, the thing to avoid is a banner designed to look like a download button. Use the Download button next to your converted file, and ignore anything asking you to install a browser extension or app to finish.
Common conversions that never leave your device
For the formats most people convert, the browser can do the job locally. Stayput’s image converter handles JPG, PNG, WebP, HEIC, AVIF, TIFF and GIF; HEIC to JPG fixes iPhone photos; Image to PDF turns photos or scans into a PDF; and Video to MP3 extracts a soundtrack. The file is processed in the page, there are no ads, and after one visit and a short wait airplane mode proves it.
Convertio supports hundreds of formats that browsers cannot read, so for those a server is the only practical route. Keep it for files that would not matter if a stranger saw them.
A quick test for any converter
The network panel in your browser shows every request a page makes; an upload looks like one request roughly the size of your file. Does this website upload my files? explains that check and the faster airplane-mode test.
