swapfile.io
99 free file tools that never upload your files
What it does
swapfile.io is a hub of 99 free tools that run in your browser: convert images, PDFs and audio, crop/rotate/watermark images, strip EXIF/GPS/C2PA metadata, and use developer & CTF utilities (file analyzer, hash & cipher ID, regex, diff, QR, JWT, base64…). Most tools process your file entirely on-device — nothing is uploaded, and there's no tracking. Free, no sign-up, available in 14 languages.
Convert images and clean EXIF, GPS and C2PA metadata without uploading anything. Conversion runs in your browser; your files never leave your device.
Conversion runs in your browser. Your file is not uploaded to a server. Editing apps embed a "created with AI" (C2PA) credential plus EXIF/GPS data into your photo. swapfile.io removes them; the pixels and resolution of your image stay exactly the same. Instagram, TikTok and X automatically mark images carrying C2PA credentials with an "AI info" label. swapfile.io removes the metadata behind it; framing, resolution and color stay thefrom swapfile.io
