Why Compress to Exactly 100KB?
Many online forms and portals have strict file size limits. Common scenarios:
- Government portals — Passport, visa, and ID photo uploads often require under 100KB
- Job applications — Resume photo uploads with size restrictions
- University admissions — Student photo submissions
- Web forms — Profile picture uploads with file size caps
- Email attachments — Keeping images lightweight for faster sending
How to Compress to Exactly 100KB
Step 1: Upload Your Image
Go to the Image Compressor and upload any image — JPEG, PNG, WebP, GIF, or HEIC.
Step 2: Select Target Size
Choose "Exact KB" mode and enter 100 as your target size. The tool uses binary search to find the optimal quality that hits your exact target.
Step 3: Preview and Download

Common File Size Targets
| Use Case | Recommended Size |
|----------|-----------------|
| Government ID photos | 20KB - 50KB |

Tips for Better Compression
1. Start with the right format — JPEG compresses better than PNG for photos
2. Resize first if possible — Smaller dimensions = smaller file size
3. Use the preview — Check visual quality before downloading
4. Try different quality levels — Sometimes 90% quality hits your target with better visuals
