Common questions
How this tool behaves
Where is a 1 MB limit common?
Job portals, visa and passport appointment systems, college admissions, insurance claims and many email services cap a single image at 1 MB. Marketplace listings and support ticket forms often do too.
Will my photo lose quality?
The engine tries the highest JPEG quality first and steps down only as far as needed. For a typical phone photo the change is not visible at normal viewing sizes. If the photo is very large, also set a maximum dimension such as 3000 px.
Is 1 MB 1000 KB or 1024 KB?
Portals differ. This page uses 1024 KB per MB, so the default target is 1024 KB. If your form says "1000 KB", type that number into the target field instead.
Can I keep PNG transparency?
No. The output is JPEG so the size can be controlled precisely, and transparent areas become white. Use the PNG optimiser if you must keep transparency.
Does the file leave my device?
No. The image is decoded and re-encoded by your browser. ImgNimble does not receive the source file on this page, and refreshing clears both the input and the generated result.
What if it still does not fit?
Lower the maximum dimension and run again. The engine also stops at a minimum quality safeguard rather than producing an unusable image.
Practical checks
