About ConvertFileBox
ConvertFileBox is a free online file converter supporting more than 140 image formats including HEIC, AVIF, WEBP, PNG, JPG, and TIFF. The tool is designed for anyone who needs to convert image files quickly — iPhone users trying to open photos on Windows, designers working with modern formats, developers preparing assets for the web, or anyone who has ever received an image their software could not open. No signup, no software installation, and no watermarks.
Our Mission
Our mission is simple: make image conversion accessible to everyone, for free, without friction. File format incompatibilities are a frustrating everyday problem — a photo taken on an iPhone that Windows cannot open, a design file a client cannot view, a web image a legacy browser cannot render. ConvertFileBox exists to eliminate that friction in seconds.
We believe basic file conversion tools should not sit behind paywalls, forced accounts, or ad-cluttered interfaces. There are no ads on conversion pages, no watermarks on output files, and no per-session limits on the number of conversions you can run. Files you upload are automatically and permanently deleted from our servers within 1 hour, so your data never lingers longer than necessary.

Why It's Free
ConvertFileBox is free to use and always will be. There are no ads, no watermarks, and no upsells. The service is supported by a fundamental belief that basic file conversion should not require a subscription, account, or paywall. Everyone deserves access to tools that make their daily work easier.
