Frequently Asked Questions
Is FileChange actually free?
Yes — completely free. No hidden trial, no credit card, no "free tier that expires." Convert as many files as you like, as often as you like.
What happens to my files?
Nothing — because they never go anywhere. FileChange runs entirely in your browser. Your files are not uploaded to any server, not stored, not analyzed. The conversion happens on your own device and the result downloads straight to you.
Is it safe to convert sensitive documents?
Yes. Because nothing leaves your device, FileChange is safe to use with confidential files, personal photos, private documents — anything. There is no server receiving your data, so there is nothing to breach or leak.
What file formats do you support?
FileChange handles 170+ conversions across image, video, audio and document formats: images (JPG, PNG, WEBP, HEIC, SVG, AVIF, GIF, BMP, TIFF, ICO), video (MP4, MOV, AVI, MKV, WEBM, FLV, WMV, 3GP), audio (MP3, WAV, FLAC, AAC, OGG, M4A, OPUS, WMA, AIFF), and documents (PDF, DOCX, XLSX, PPTX, TXT, HTML, CSV, JSON, XML, Markdown).
Can I convert multiple files at once?
Yes. Drop as many files as you like in one batch and convert them all in a single click — free, no account required.
Is there a file size limit?
No hard limit. Your device's available memory is the real ceiling. Typical conversions handle hundreds of MB comfortably. Very large files may be slow or fail on low-memory devices.
How fast are conversions?
Images convert in milliseconds. Documents take 3-10 seconds. Video and audio depend on length and your device — most clips under 5 minutes are done in under 30 seconds.
Do I need to create an account?
No account, no email, no sign-up of any kind. Open the site, drop your file, download the result. Done.
