Whatever you pick
Five questions to ask any image tool.
01
Is the picture uploaded?
For which jobs, to where, and how long is it kept?
02
Which formats really come out?
Ask for the file, not the label — especially for AVIF and HEIC.
03
What are the limits?
Per batch, per file, per day — and what lifts them?
04
What happens to the metadata?
Location and camera data: kept, stripped, or your choice?
05
Does it say what it can't do?
A tool that's plain about its edges is easier to trust with the rest.
