Frequently Asked Questions
Why do exam forms reject large photos?
Application servers have strict storage limits to handle millions of candidate uploads smoothly. Large photos slow down database servers and cause portal crashes during peak registration hours.
Does this tool reduce image dimensions?
It scales down file weight by optimizing pixel compression rather than aggressive cropping. Your photo dimensions stay proportional so your face or text remains clearly visible.
Is this image compressor completely free?
Yes, you can compress as many files as you need without any hidden fees. There are no subscriptions, mandatory signups, or trial period restrictions applied here.
Can I use my smartphone to compress images?
The tool runs entirely inside your mobile web browser without requiring any app downloads. You can upload photos directly from your phone gallery with zero hassle.
What if my photo is still too big?
If 100KB is still too large for a strict form, you can try our Resize Image to 50KB tool instead. Simply select the lower target size option for strict document portals.
