KakaoTalk documents one clean rule: up to 300 MB per file, and it is the same on Android, on the PC app, and for every file type — video, images, voice, archives. There is no premium tier that raises it; paid extras change storage and backup, never the send cap. So a holiday video from a modern phone camera, easily a gigabyte for a few minutes of 4K, needs roughly a two-thirds cut before Kakao will take it.
300 MB is a generous budget when the encoder targets it honestly: several minutes of footage keep near-original quality, and even 10–15 minutes stay sharp. The compressor aims at the byte count with a safety margin — no failed sends at 301 MB — and the whole job runs on your own device, so the video goes from your gallery to the chat without visiting anyone's server first.

Frequently asked questions
What is KakaoTalk's file size limit?
300 MB per file, stated in Kakao's own help pages for both the mobile app and the PC version, and it applies to every file type. There is no bigger tier to buy — 300 MB is the ceiling for everyone.
How much video fits well in 300 MB?
Around five minutes of phone footage keeps close-to-original quality, and 10–15 minutes still look sharp. The compressor always picks the highest resolution the byte budget can sustain rather than smearing the picture.
Why did a "300 MB" video fail to send?
Because size checks are exact and file managers round generously — a file shown as 300 MB can be a few hundred kilobytes over the real cap. ConvertUno lands safely under the target, so the send passes.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
