Frequently Asked Questions
Why does Convertio have a 100MB file limit?
Convertio processes files on their servers, so they limit file sizes to manage server costs. noupload has no such limit since your own device handles the processing.
Is Convertio safe for sensitive files?
Convertio encrypts uploads and deletes files after 24 hours, but your files still pass through their servers. noupload never uploads files, making it inherently more private.
Can noupload convert video or audio files?
No. noupload focuses on image and PDF tools. For video or audio conversion, Convertio or a desktop tool like HandBrake may be more appropriate.
Which is better for batch image conversion?
noupload handles batch image conversion with no per-file limits and instant processing. Convertio's free tier limits you to 10 conversions per day, making it impractical for large batches.
