Compress Image Between 50KB and 100KB — Free, Fast & Private
A form that names a 50 to 100 KB band is usually asking for something bigger than a face: a handwritten declaration, a full-page scan, a larger photograph. Portals refuse a file under the lower figure as readily as one over the upper. This page opens the compressor in JPEG with a 100 KB ceiling. A band this wide leaves the encoder room: many photographs keep their full dimensions here and give up only quality, so the result tends to sit close to 100 KB. The floor matters mostly for small or simple pictures that would finish well under it.
What the tool does, and what it does not
The compressor takes a ceiling: it searches for the highest quality at which the file is still under 100 KB, which tends to leave the result close to the ceiling, not far below it. That is the right behaviour for a range, because the highest quality that fits is also the file most likely to sit above the floor. But the image compressor has no floor setting: it will not enlarge a file to reach 50 KB, and it does not pad one with filler data. A picture whose own best encode is already below the floor stays below it.
Who asks for 50 to 100 KB
Among the exam documents MiniPx has checked, the bodies that state this exact band are the banking recruiters, for the handwritten declaration — a paragraph the candidate copies out by hand, signs and uploads as an image. Larger photographs and scanned certificates often land here too, but the forms in the table are the ones whose own notice states it.
| Exam | Document | Stated size | Checked |
|---|---|---|---|
| IBPS PO / Clerk (CRP-XVI) | Handwritten declaration | 50–100 KB | 2026-10-05 |
| SBI PO / Clerk 2026 | Handwritten declaration | 50–100 KB | 2026-10-05 |
Keeping handwriting legible
A declaration is a page of fine strokes, and what a reviewer checks is whether it can be read. Legibility depends more on pixel dimensions than on JPEG quality: shrink the page too far and letters merge, however clean the encode. Photograph or scan the sheet flat, in even light, cropped to the written area, and let the 100 KB budget go on resolution. If the tool has to reduce dimensions to fit, zoom the result to full size and read a full line before uploading — and check the floor as well, because a small, heavily cropped capture can still come in under 50 KB.
What fits in 100 KB — measured on this page
We dropped five real files on the compressor above and kept what it handed back. 5 of 5 came out under 100 KB; one was made smaller in pixels to get there, because past a point the bytes can only come from pixels.
| File | Before | After, on this page | Under 100 KB? |
|---|---|---|---|
| 12 MP phone photo | 4032 × 3024 px · 3.73 MB | 2580 × 1935 px · 88.8 KB | Yes |
| Portrait / headshot | 3264 × 4653 px · 2.25 MB | 3264 × 4653 px · 92.7 KB | Yes |
| Scanned handwritten page | 3349 × 4281 px · 2.17 MB | 3349 × 4281 px · 95.9 KB | Yes |
| Scanned signature | 2041 × 617 px · 109.1 KB | 2041 × 617 px · 61.8 KB | Yes |
| Screenshot (PNG) | 1280 × 800 px · 88.1 KB | 1280 × 800 px · 97.4 KB — larger than the original (PNG made into JPG) | Yes |
Measured 2026-10-06 in Chromium 145.0.7632.6 with this page’s own settings. The photos are public-domain and CC0 files from Wikimedia Commons; the screenshot is our own. Sizes read as the tool shows them (1 KB = 1,024 bytes); the target itself is 100,000 bytes, which is under 100 KB on either reading.
Of the 5 real files in that table, 5 finished inside the range, between 50 KB and the ceiling..
If the result is under 50 KB
Read the size on the result screen against 50 KB before downloading. In a band this wide, landing under the floor means the capture itself is small: photograph or scan the page again at a higher resolution so the writing has more pixels, then compress.
Decimal kilobytes
Kilobytes here are 1,000 bytes. A portal counting 1,024-byte kilobytes sees every file a little smaller, so a declaration just above 50 KB by our count can read as just under it there. Leave a small margin above the floor.
