Compress Images to Under 100KB Online Free
Overview
Government portals, college application forms, and job boards often cap profile photo or document image uploads at 100KB or 200KB. The compressor lets you drag a quality slider until the estimated output size drops below your target before downloading.
How to Use This Tool
Upload your image. Drag the quality slider down until the estimated size reads below 100KB. Click Compress and download. If the image is still above 100KB at minimum quality, reduce the pixel dimensions and try again.

Can I always get an image under 100KB?
For typical profile photos (800x800px), yes. For very high-resolution images, you may also need to reduce dimensions. A 4000x3000px image has 12M pixels; halving the dimensions to 2000x1500px drops size by 75%.
What size should a passport photo be for online portals?
Most Indian government portals (UPSC, SSC, visa applications) require passport photos between 20KB and 100KB at 200x200px to 400x600px depending on the specific form.
Does compressing under 100KB make the photo look bad?
For a face photo at 400x400px, 100KB gives you roughly 60-70% JPG quality, which is acceptable for ID photos on screen. Printing at small sizes (35x45mm) at this compression level is fine.
