RAR is a proprietary compressed archive format created for WinRAR, widely used for file sharing and backups — this converter can extract RAR archives but cannot create new ones, since real RAR encoding requires a paid license.
JAR (Java Archive) bundles compiled Java class files, resources, and a manifest into a single package for distributing Java applications and libraries — technically the same ZIP container under Java's own naming and structure convention.
Frequently asked questions
help
Is it free?
Yes — converting files on TransConvert is free, with no sign-up required.
help
Does converting reduce quality?
It depends on the formats involved — some conversions keep everything exactly, others may show a small trade-off if the target format itself is lossy. We never add any extra compression beyond what the format requires.
help
Is my file kept afterwards?
No — files are processed to produce your download and are not kept afterwards.
help
What's the largest file I can convert?
Files up to 1 GB are supported.
