Drop your SNAP photograph, get a JPEG inside the 10–100 KB window — the size every published reading of the snaptest.org spec accepts without the portal recompressing it. Nothing is uploaded; it all runs in your browser.
The SNAP application (snaptest.org — registration typically opens early August and runs to about November 20, with the tests held in December) takes one image upload: a recent scanned colour passport-size photograph, JPG/JPEG, not older than 6 months. Symbiosis doesn't publish KB or pixel numbers on the official instructions; the window guides have carried consistently for years is 10–100 KB, and recent cycles' portal reportedly accepts larger files but automatically recompresses anything over 100 KB. That's the reason to size it yourself: a file already inside 10–100 KB uploads as-is at the quality you chose, instead of whatever the portal's resizer produces. This page is preset to that window.
SNAP's form treats the photograph like your name and date of birth: once saved, it can't be changed for the cycle, and the same photo flows to your admit card and the test-day identity check. Upload the right file the first time — a clear, recent, front-facing shot against a white or plain light background, face fully visible, no caps or dark glasses. PixFit can't check any of that composition; it only gets the bytes right.
No official pixel dimensions exist for SNAP — “passport-size” is the whole spec, so this page presets no Exact size. Keep the usual passport shape (a bit taller than wide, roughly 3.5×4.5 cm proportions); if your source is a wide phone shot, type something like 350x450 into Exact size above and PixFit crops to it — drag the crop preview so your head sits centred with clear space around it. iPhone HEIC works: drop it straight in, it's decoded in your browser and comes out as the JPEG the portal wants.
Guides disagree here — at least one widely-read article says in one paragraph that you upload a scanned signature and in another that SNAP, unlike most MBA entrance exams, doesn't take a signature upload at all. Recent-cycle walkthroughs consistently show only the photograph slot. Trust the form in front of you: if your cycle's application shows a signature upload, follow the limits its widget states — and the scanning advice on the CAT page applies to any signature scan unchanged.
PixFit runs entirely in your browser: nothing is uploaded to any server, and re-encoding strips EXIF metadata (including GPS) from phone photos as a side effect. It binary-searches for the best JPEG quality that fits under 100 KB — and if a clean scan lands under the 10 KB floor, it pads the JPEG with a spec-valid comment segment to meet it. Applying to other MBA exams this season? The CAT and XAT pages cover their (different) upload formats. If anything on the snaptest.org form disagrees with this page, the portal wins.
