Why use browser-based tools instead of upload sites?
Most free file tools work by uploading your file to a server, processing it there and sending a copy back. That's fine for a meme. It's less fine for a scan of your passport, a contract, a photo of your kids or a video recorded at home, because the file now sits on a computer you know nothing about.
KitFuse does the work inside your browser instead. When you open a tool, your browser downloads a small program. From then on, your files are read from your device, processed in memory and handed back to you as a normal download. There is no upload step, so there is nothing to leak, log or keep.
- Private by design: files never leave your device, which you can confirm by switching to airplane mode after the page loads.
- Fast: no waiting for uploads and downloads, which matters for large photos and videos on mobile data.
- Free and unlimited: no account, no daily limits and no watermarks.
What you can do with KitFuse
The tools fall into four groups. Privacy tools find and remove hidden data such as GPS location, camera serial numbers and author names from photos, videos and PDFs, and let you blur faces or number plates before sharing. Image tools convert between formats, turn iPhone HEIC photos into JPG, compress and resize. Video tools make GIFs from videos, turn GIFs into MP4 and remove the sound from a video. PDF tools combine images into a PDF, merge and split documents.
Your files carry more than you think
Every photo from a phone stores the exact place it was taken, the phone model and the time, down to the second. Videos do the same, and PDFs often record the author's name, the company and the app that made them. This hidden layer is called metadata. KitFuse shows it to you before you share a file, and every tool that creates a new file leaves that layer out by default.

Frequently asked questions
Are my files uploaded anywhere?
No. Every KitFuse tool runs inside your browser using JavaScript and WebAssembly. Your files are processed in your device's memory and never sent to a server. You can check by loading a tool, switching to airplane mode and using it: it keeps working.
Is KitFuse really free?
Yes. There's no sign-up, no watermark and no daily limit. The site is supported by ads, and KitFuse never sends your files to advertisers or anyone else.
Do the tools work on iPhone and Android?
Yes. All tools work in mobile browsers such as Safari and Chrome. You can pick files from your gallery or camera roll, and on most phones you can save results straight back to your photos.
Which languages is KitFuse available in?
The tools are available in English, Spanish, Portuguese, French, Arabic, Hindi and Indonesian. Use the language menu at the top of any page to switch.
