Reduce Image Size in KB
Compress your photo to an exact file size limit — whether a portal asks for 50KB, 100KB, or 200KB. No more repeated trial and error.
Government portals, college application forms, and visa websites all have strict file size requirements. Uploading a 2MB selfie to a form that asks for max 50KB will be instantly rejected. GenZDoc lets you set an exact target size in KB. Our compression engine then intelligently adjusts quality levels to hit that target as closely as possible — typically within 5% of the specified limit.

Frequently Asked Questions
Can I compress to exactly 50KB?
Yes. Enter "50" as your target and our engine will compress to as close to 50KB as possible, always staying under the limit.
Will my face still be recognizable after compressing to 50KB?
Yes. At 50KB a standard passport photo (200x200px to 600x600px) remains perfectly clear and is accepted by all major government systems.
What formats are supported?
JPG, PNG, and WEBP. Output is always JPG, as it achieves the smallest file size for photographic images.
