Compress Photo Under 100 KB
Compress any photo to strictly under 100 KB for government exam portals (SSC, UPSC, IBPS), online job applications, and student registration forms. The output is guaranteed to be below the 100 KB limit — not just approximately 100 KB. No upload, no signup.
Set the target to under 100 KB and download a photo that will pass any portal check. Open the compress tool →
How it works (3 steps)
- Upload your photo. The file stays in your browser — it is never sent to any server.
- Set target to under 100 KB. The tool targets 95–99 KB to give a safe margin below the limit while keeping maximum quality.
- Download and upload to the portal. Verify the file size in your file manager before submitting to the exam or job portal.
Perfect for...
- Government exam portals such as SSC, UPSC, IBPS, and other competitive exam applications that require photos strictly under 100 KB
- Online job applications on government recruitment portals where file size validation is strict
- Student registration forms for university admissions and scholarship portals
- Any portal where the error message says "file size must be less than 100 KB"
Tips for compressing a photo under 100 KB
- Use JPG format — JPG compresses photos far more efficiently than PNG. A 200×200 px portrait photo in JPG at 80% quality is typically 15–30 KB, well under 100 KB.
- Resize dimensions if needed — if your photo is large (e.g. 2000×2000 px) and must be under 100 KB, resize it to the portal's required pixel dimensions first (usually 200–300 px), then compress.
- Target 95 KB, not 100 KB — leave a 5 KB margin to avoid edge cases with strict inequality checks on portal servers.
- Do not re-save before uploading — once you download the compressed photo, upload it directly to the portal. Re-saving in another application can change the file size unexpectedly.
FAQ
What is the difference between "compress to 100 KB" and "compress under 100 KB"?
Compress to 100 KB targets approximately 100 KB — may be 1–2 KB over. Compress under 100 KB guarantees strictly less than 100 KB. UploadReady targets 95–99 KB for a safe margin while preserving maximum quality.
Why do portals say "under 100 KB" instead of "exactly 100 KB"?
It is easier to validate programmatically — the server rejects any file where filesize ≥ 100,000 bytes. Targeting 95–99 KB is the safest approach for all portal types.
How do I ensure my photo stays under 100 KB after uploading?
Download the compressed photo and check the file size in your file manager (Properties on Windows, Get Info on Mac). If it shows under 100 KB or under 100,000 bytes, it will pass. Do not re-save in another application before uploading.
What is the best format for a photo under 100 KB?
JPG. A 300×300 px portrait in JPG at 80% quality is typically 20–50 KB — well under the limit with excellent quality. Most government exam portals also require JPEG format explicitly.
Will my photo still be under 100 KB after sending as an email attachment?
Yes — if it is under 100 KB on your device, it will be under 100 KB as an attachment. Email clients do not recompress attachments unless you explicitly choose to send a smaller size.
