Some government exam portals and defence recruitment forms require photos or signature images under 10 KB — one of the strictest size limits in Indian online applications. A 10 KB photo is challenging but achievable, especially for signature-size images. Use PhotoFit to compress any photo to exactly 10 KB in seconds, free, with no upload required.
| Signature uploads | Most exam portals require signature images under 10–20 KB |
| NDA/NA application | 4–40 KB limit — 10 KB is a safe middle target |
| CDS/CAPF | Some portals cap signatures at 10 KB |
| Defence recruitment | ARO (Army Recruitment Office) portals often use 10 KB limit |
| Railway (RRB) | Signature: 10–40 KB on some RRB portals |
| State PSC portals | Several state portals have 10 KB limits for thumb impressions |
The key to a good-looking 10 KB photo is to first resize the image to the smallest required dimensions. A 200×230 px image at 10 KB will look much better than a 600×800 px image at 10 KB, because the pixel density is maintained. Resize first, then compress.
Most portals requiring 10 KB are asking for your signature scan, not your passport photo. Signature images are small (typically 140×60 px), so 10 KB gives them enough quality. If you are asked for a 10 KB face photo, contact the portal's helpdesk — this is unusually strict and may be a documentation error.
Yes, with the right technique. For a signature or small thumbnail (200×230 px or smaller), 10 KB is enough to preserve readability. For a full face passport photo at 3.5×4.5 cm, 10 KB will look very pixelated. Most portals that require 10 KB are expecting small signature images, not full portrait photos. Use PhotoFit to target exactly 10 KB.
Common portals with 10 KB limits include: NDA/NA application (photo: 4–40 KB, signature: 4–30 KB), some RRB (Railway) portals, ARO defence recruitment portals, and various state government PSC portals. Always check your specific application form before compressing.
Open PhotoFit, go to the Compress tab, upload your photo, and set the target size to 10 KB. PhotoFit will reduce image quality iteratively until the file reaches your target. For best results at 10 KB, also resize the image to smaller dimensions (like 200×230 px) before compressing — smaller pixels mean better quality at low file sizes.
JPEG is by far the most efficient format at very small file sizes. PNG at 10 KB will look worse than JPEG at 10 KB because PNG does not use lossy compression. Always save as JPEG when targeting 10 KB or less.
