Frequently Asked Questions
How do I reduce an image to exactly 100KB?
Upload your image and click Compress — quality is pre-configured for 100KB targets. If still over 100KB, resize the pixel dimensions to 600–800px wide first using the Resize tool.
Why do forms require images under 100KB?
Government portals and job application forms set 100KB limits to reduce server load and ensure consistent document handling.
Will compressing to 100KB ruin the quality?
For images under 800px wide, 100KB looks fine on screen. For online forms, passport uploads, and job applications it is perfectly acceptable. For print, results may vary.
What if my image is still over 100KB after compressing?
Resize the pixel dimensions smaller first (e.g. 700px wide) using the Resize tool, then compress. The combination easily gets below 100KB.
