Maria L.
Viewer app
I’ve been using this online file viewer for a while now, and it’s become my go-to tool. It’s super easy to use—just upload and view, no hassle. I love that it supports so many file types. It’s saved me a ton of time, especially when I’m working on the go. Definitely recommend it!
Alex B.
Conversion app
I use this file conversion app mainly for medical files—it's fast, reliable, and preserves formatting. Only downside is the lack of batch processing support.
Bob V.
Merger app
As a student, this DOCX merger app is super handy! Easy to use, but wish it merged faster.
ALEXEY M.
Metadata app
I use this image metadata cleaner app regularly for sharing photos online. It’s simple, fast, and gives me peace of mind knowing personal info is stripped out. The interface is clean and easy to navigate—perfect for anyone who wants quick and secure photo sharing without extra hassle.
Mikhail Z.
Scanner app
The QR code scanner works great—fast, accurate, and easy to use. I use it often for menus, payments, and links. It rarely misses a scan and the interface is clean. However, it does show ads after some scans, which can be a bit annoying. Still, a reliable tool for everyday use.
William N.
Editor app
I use this PPTX editor app all the time for quick fixes on my presentations. It’s easy and straightforward, though I wish it had more advanced features.
