Frequently Asked Questions
Does compressing to 100KB reduce image quality?
Yes, some quality reduction is inevitable when compressing to a specific file size. However, our binary-search algorithm finds the highest possible quality that still meets your 100KB target, so quality loss is minimized.
Is my image uploaded to a server?
No. All processing happens entirely inside your web browser using the HTML5 Canvas API. Your images are never sent to any server, never stored anywhere, and never seen by anyone other than you.
How do I compress a photo to 100KB for a government form?
Upload your photo to this tool with the 100 KB preset selected. The tool will compress your image to under 100KB while keeping the best possible quality. The resulting JPEG is accepted by most government portals, UPSC, SSC, and university admission forms.
