Why compress to 50KB?
50KB sits just above the strictest signature-only limits and covers a wide band of Indian recruitment, passport, and ID-card portals that ask for a photo "up to 50KB." It's tight enough that a straight-out- of-camera photo (routinely 2–8MB) needs real compression, but loose enough to hold noticeably more detail than a 20KB signature limit allows. Portals settle on this figure for the same reason smaller limits exist — predictable storage and upload times across thousands of simultaneous submissions — while giving applicants a photo that still looks like them rather than a blurred thumbnail.
| Form | Photo Size | Signature Size | Dimensions |
|---|---|---|---|
| SSC CGL | 20KB–50KB | 10KB–20KB | Photo 3.5×4.5cm · Signature ~140×60px |
| IBPS PO | 20KB–50KB | 10KB–20KB | Photo ~200×230px · Signature ~140×60px |
| UPSC | 20KB–300KB | 20KB–150KB | Photo ~300×300px |
| NEET | 10KB–200KB | 4KB–30KB | Passport-size photo |
| Passport (India) | Up to ~100KB | — | 4.5×3.5cm photo |
| PAN Card | Up to ~50KB | Up to ~50KB | Passport-size photo |
Treat these as typical ranges, not a live rulebook — every recruitment cycle can shift the exact number, so double-check your form's notification PDF. If it says 50KB, this page's default is already set.
How it works — quality vs. size
Most "compress to 50KB" tools pick one quality setting — commonly 80% — and hope it lands near the target, which overshoots on a detailed photo and wastes quality on a simple one. This tool instead binary-searches JPEG/WebP quality: it tries a setting, checks the output size, and narrows in over up to 7 attempts until it lands within 5% of 50KB at the highest quality that still fits. Only if quality alone can't get there — a very large or highly detailed source image — does it reduce dimensions in 10% steps and search again, rather than giving up or forcing an ugly result.
Why on-device beats server upload
A passport-style photo used for a government form is exactly the kind of file you don't want sitting on a stranger's server while it gets compressed. This tool runs entirely in your browser using the Canvas API — the same engine your browser already uses to draw every image on the page — so your photo is never transmitted anywhere and there's no upload wait on a slow connection. The same Canvas re-encode that shrinks the file also strips EXIF metadata automatically, including any GPS location the camera embedded.
Supported formats
Upload JPG, PNG, or WebP. Output JPG, PNG, WebP, or leave it on Auto, which defaults to JPG for compatibility with government and exam portals and only switches to WebP automatically when your image has transparency you've asked to preserve, since JPEG has no alpha channel to hold it.
Need a different size?
Need a format change instead of a size change? Image to JPG and Image to WebP are coming soon — pick JPEG or WebP as the output format in Advanced above meanwhile.
Frequently Asked Questions
Will my photo look noticeably worse at 50KB?
Some quality loss is unavoidable when a multi-megabyte camera photo has to fit 50KB, but this tool searches for the highest quality that still hits the target rather than applying one fixed setting — most passport-style photos at typical upload dimensions stay clearly recognisable at 50KB. If your form allows more, a 100KB or 200KB target will keep more detail.
Is 50KB a hard maximum or does it need to be close to 50KB?
This tool targets within 5% of 50KB and stops once it lands at or under that size, so the result respects a "maximum 50KB" rule reliably. It does not try to land exactly on 50KB from below if a smaller file would also work — the goal is fitting the limit at the best possible quality, not hitting a precise byte count.
What formats can I upload and download?
Upload JPG, PNG, or WebP. Output JPG, PNG, or WebP — or leave it on "Auto," which defaults to JPG for the widest compatibility with form and portal uploads, switching to WebP only if your image has transparency you've asked to keep.
Can I compress several photos at once?
Yes, up to 10 images in a single batch, each compressed to the same 50KB target — useful when a form wants a photo and a signature, or you're preparing images for multiple family members' applications.
Where does my photo go when I compress it?
Nowhere but your own device. The whole operation happens in your browser via the Canvas API — your photo is read, resized, and re-encoded locally, and EXIF metadata (including GPS) is stripped automatically as part of that re-encoding.
