100KB — The Standard for Passport and Visa Photos
When applying for a passport, visa, or submitting documents to a university portal, 100KB is the most common file size limit. High-resolution photos from modern smartphones easily exceed 4MB, causing automated portals to reject the file. This tool compresses your photo iteratively, finding the absolute best possible visual quality that fits under the 100KB limit.
Common 100KB Requirements — Portal Guide
| Portal / Document | File Size Max | Format | Dimensions |
|---|---|---|---|
| Indian Passport Seva | 100KB (sometimes 50KB) | JPG | 4.5 x 3.5 cm |
| US Visa (DS-160) | 240KB (100KB recommended) | JPG | 2 x 2 inches |
| Schengen Visa | 100KB - 200KB | JPG | 4.5 x 3.5 cm |
| UGC NET / NTA forms | 200KB (Photos) | JPG | Varies |
| PAN Card / NSDL | 50KB - 100KB | JPG | Varies |
How does the 100KB Compressor Work?
Our compressor uses a smart iterative algorithm. It starts by attempting to compress your photo purely by reducing JPEG quality, which maintains the original dimensions. If the photo is still over 100KB at the lowest acceptable quality threshold, it will then automatically (and proportionally) reduce the pixel dimensions of the image. It repeats this process up to 55 times in milliseconds until it hits the perfect balance of quality and file size.
Frequently Asked Questions
Will compressing to 100KB blur my photo? ▾
For a standard passport photo consisting of a head and shoulders, 100KB is more than enough data to keep the image crystal clear. If you upload a complex, high-resolution landscape photo and force it to 100KB, it will lose detail. For best results, crop your photo to the subject before compressing.
Is it safe to upload my passport photo here? ▾
Yes — because you aren't actually uploading it anywhere. The "upload" button simply loads the image into your own browser's memory. The compression is powered by the HTML5 Canvas API running on your local device CPU. No image data is ever sent over the internet to our servers.
The portal says my file is still too large. Why? ▾
This tool guarantees the file will be at or slightly below 100KB (e.g., 99.5KB). Some extremely strict, older portals might calculate KB differently (using 1000 bytes instead of 1024 bytes). If the portal rejects it, simply use the 50KB compressor tool instead, which will comfortably pass any 100KB check.
