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.
