Frequently asked questions
A few common questions about how TransConvert works.
help
How does hitting a target size actually work?
JPG/WEBP search for the closest quality setting, PNG searches palette size, and GIF does both — whichever lands nearest your target.
help
Will it hit the target exactly?
We aim for it, not guarantee it — the result depends on how compressible the file already is.
help
Does compression reduce quality?
Yes — that's the trade-off for a smaller size, and it shows more at lower targets.
help
Can I compress several files at once?
Yes — add multiple files and download them individually or together as a zip.
help
What's the largest file I can compress?
Files up to 1 GB each are supported.
Handled with real security practices
A few specifics, not boilerplate claims.
Nothing compressed until you press Compress
Choosing files and setting your compression level happens locally — your file is only uploaded once you start the job.
No file retention
Your file is processed only long enough to build your download, then deleted immediately.
Abuse protection
Every upload is size-checked, and abusive IP addresses can be blocked instantly.
