Frequently asked questions
How does ExamKB hit an exact KB size?
It compresses your image, checks the file size, and adjusts quality up or down repeatedly until it lands at or just under your target. If even the lowest quality is too big, it reduces the pixel dimensions and retries.
Is my photo uploaded to a server?
No. Everything runs inside your browser on your own device, so your photo stays private and it works even on a slow connection.
Does it support iPhone HEIC photos?
Yes. HEIC and HEIF files are converted to JPG automatically before compressing.
Is ExamKB free?
Completely free, with no sign-up, no daily limit and no watermark.
