Why Do You Need to Compress JPG to 100KB?
Many online forms and applications have strict image size requirements:
- Government job applications (SSC, UPSC, Railways): 20KB to 100KB
- Bank account opening: Photo under 100KB
- College admission forms: 50KB to 100KB
- Passport applications: Specific size requirements
- Online registration portals: Various limits
The Problem with Traditional Image Compressors
Most online image compressors have serious issues:
- They upload your photos to their servers - Privacy risk for personal documents
- They add watermarks - Unusable for official documents
- They require signup/payment - Frustrating when you need quick results
- They don't let you target exact file sizes - You need 100KB, not "smaller"
How to Compress JPG to Exactly 100KB (Step-by-Step)
Method 1: Using EverydayPDF Image Compressor (Recommended)
Our tool runs 100% in your browser - your image never leaves your device.
- Go to EverydayPDF Image Compressor
- Drag and drop your JPG image (or click to select)
- Adjust the quality slider until you reach ~100KB
- Click "Download" to save your compressed image
💡 Pro Tip: Target Slightly Under
If a form requires "under 100KB", aim for 95-98KB. Some systems are strict about the exact limit.
Method 2: Using Image Resize + Compression
If quality compression alone doesn't get you to 100KB:
- First, resize your image to smaller dimensions
- Then compress it with the quality slider
- This combined approach maintains better visual quality
Common Size Requirements by Application Type
| Application | Photo Size | Dimensions |
|---|---|---|
| SSC Exam Forms | 4KB - 100KB | 3.5cm x 4.5cm |
| UPSC Applications | 20KB - 300KB | 2" x 2" |
| Bank KYC | Under 100KB | Passport size |
| College Admissions | 50KB - 200KB | Varies |
| Job Portals | Under 100KB | Square/Passport |
Why Privacy Matters When Compressing Photos
When you upload a passport photo or ID photo to a random website, you're trusting them with:
- Your face (biometric data)
- Your personal documents
- EXIF data (location, device info)
EverydayPDF processes everything locally in your browser. Your photos never leave your device.
Frequently Asked Questions
Can I compress JPG to 100KB on my phone?
Yes! EverydayPDF works on any device with a browser - iPhone, Android, tablet, or computer. No app installation needed.
Will compressing to 100KB reduce photo quality?
Some quality loss is inevitable when reducing file size significantly. However, for passport-size photos displayed on screen, the difference is usually not noticeable.
What if my photo is already under 100KB?
Great! You don't need to compress it further. If you need to increase the file size (rare), you can save it at higher quality.
Can I compress PNG to 100KB?
Yes, but consider converting PNG to JPG first for better compression. PNG files are typically larger because they're lossless. Use our Image Converter to switch formats.
