Why compress large JPG files to 50KB or 100KB?
Many online forms and portals reject images that are larger than a specific file size, even if the image
quality is good. This happens because:
Government websites and exam portals have server upload limits to reduce load times and storage costs.
Job application systems enforce file size rules to process thousands of applications efficiently.
University admission portals set size limits to ensure fast form submissions during peak periods.
Passport and ID card systems require small file sizes for quick database storage and retrieval.
Compressing your JPG to 50KB or 100KB ensures your image is accepted without rejection, while still
maintaining enough visual quality for official use.

Tips for compressing large JPG files to 50KB or 100KB
Start with JPEG format: JPEG compresses better than PNG for photographs. If your
original image is PNG, Compressly will automatically convert it to JPEG when you select a very small
target size like 50KB.
Use Target (KB) for exact sizes: Entering a target size like 50 or 100 in the Target
(KB) box ensures your final file will be at or below that limit, making it safe for any upload system.
Check the preview: After compression, use the before/after comparison on Compressly to
make sure important details like faces, text and edges remain clear.
Keep a backup: Save your original large JPG file before compressing, especially if
you need it for future use or printing.
Aim slightly below the limit: If a form requires 100KB, try setting your target to
95KB to avoid rejection due to rounding or encoding differences.
50KB vs 100KB: Which size should you choose?
The target size you choose depends on the specific requirement of the form or portal you are uploading to:
Compress to 50KB when:
The form explicitly states a maximum of 50KB (common in Tamil Nadu PSC and some government portals).
You are uploading a signature image, which is usually smaller than a photo.
The portal has very strict size limits and rejects anything above 50KB.
Compress to 100KB when:
The form allows up to 100KB (common in Kerala PSC, university admissions and most job portals).
You are uploading a passport-size photo that needs to show facial details clearly.
You want better image quality while still meeting the size requirement.
In general, 100KB gives you more room for quality, while 50KB is better for
meeting stricter limits. Compressly handles both targets easily, so you can try different
sizes and compare the results before downloading.
How Compressly compresses large JPG files
Compressly uses advanced browser-based compression to reduce JPG file sizes without uploading your images
to any server. Here's how it works:
Target-based compression: When you enter a target size like 50KB or 100KB, Compressly
automatically adjusts quality settings and applies smart downscaling to reach that exact size.
Quality optimization: The tool balances file size and visual clarity, removing
invisible details while keeping important elements like faces, text and edges sharp.
Format conversion: If needed, Compressly converts PNG images to JPEG for better
compression, ensuring you reach the target size.
Local processing: All compression happens in your browser using JavaScript and HTML5
Canvas, so your images never leave your device.
This approach makes Compressly faster, more private and more reliable than traditional online compression
tools that require file uploads.
