Questions
Are my files uploaded anywhere?
No. Every engine runs inside your browser as JavaScript and WebAssembly; a file is read into the tab's memory, compressed there and handed back as a download.
Is it free?
Yes, completely: no account, no watermark, no daily limit and no paid quality tier. The page is supported by the ads on it, never by your files.
Is there a file-size limit?
There is no server limit because nothing is uploaded. The practical ceiling is your device's memory: multi-gigabyte videos can exceed what a browser tab may allocate, especially on phones.
Does it keep transparency and photo orientation?
Yes: transparency is preserved when the output is PNG or WebP, and orientation is always applied correctly. EXIF, GPS and camera details are stripped by default; switch off Strip metadata under Options to keep them.
Why did my file barely shrink?
It was already compressed: JPEG, MP4, MP3, optimised PNG and ZIP have little redundancy left. When a result would be larger, the tool keeps your original and says so.
Can I still just make a ZIP?
Yes. Switch to ZIP Maker at the top of the tool, add files or a folder, and one standard .zip is built on your device.
