FilesFi — free forever, no signup
FilesFi (filesfi.com) is a free, no-signup toolkit that runs entirely in your web browser. Every tool — the QR code builder and all ten photo tools — processes everything on your own device. Nothing is uploaded to any server.
Make custom QR codes for websites, WiFi networks, vCards, WhatsApp, email, SMS, and phone numbers — with your colors, styles, and logo. Download print-ready PNG or SVG. Open the QR builder →
No accounts, no uploads, no tracking profiles. Your photos never leave your device. See our Privacy Policy and Cookie Policy for details.

FilesFi ("we", "us", "our") operates filesfi.com, a free, no-signup web toolkit that processes photos entirely in your browser: background removal, enhancing, vector tracing, compression/format conversion, and metadata inspection and removal.
All processing happens locally on your device using open-source browser libraries. Your photos are never uploaded to our servers, and we never see, store, or have access to them.
You must be at least 13 years old (or the minimum age in your jurisdiction) and legally able to agree to these Terms.
You agree not to process content that is illegal, infringing, defamatory, or invasive of anyone's privacy; not to upload malware or attempt to disrupt the Service; and not to misrepresent the source or ownership of files. You are solely responsible for the photos you process and for having the rights to use them.
Tool descriptions on this site state what each tool actually does. "Enhance" uses high-quality resampling and sharpening — it is classic image processing, not AI upscaling. Results vary by photo; we make no guarantee of any particular output quality.
The Service is provided "as is" and "as available" without warranties of any kind, express or implied.
To the maximum extent permitted by law, FilesFi and its operators shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service. Our total liability is limited to the amount you paid for the Service (the Service is free: $0).
We may update these Terms from time to time; continued use after changes take effect constitutes acceptance.

FilesFi processes everything entirely in your browser. Files are never uploaded to our servers, and we never see, store, analyze, or share them. When you close the tab, everything is gone.
You get 5 free uses, total. Our server stores a one-way hash of your IP + browser to count (can't be reversed). It never resets.
No signup needed. If you buy Pro ($15 once), Stripe collects your email at checkout and shares it with us so you can restore Pro on a new device. We never see your card number. Refunds: 14 days, no questions asked.
We use Google AdSense to display ads. Google may use cookies (including DoubleClick cookies) to serve ads based on your visits to this and other sites: policies.google.com/technologies/ads. We do not share your photos with advertisers — we never have them.
Depending on your jurisdiction (including the EU GDPR), you may request access to, correction of, or deletion of personal data we hold about you (e.g., server logs). Contact support@filesfi.com — we respond within 30 days.
The Service is not directed at children under 13, and we do not knowingly collect their personal data.
