Why this exact limit matters
One hundred fifty kilobytes is the ceiling that appears on systems that thought about their limits: enough for a genuine photograph, low enough to keep storage predictable. At this budget full resolution finally becomes negotiable rather than punishing — and the encoder’s quality ladder starts producing files that look like photographs instead of approximations.
A target-size compressor removes the trial and error: state the ceiling the portal enforces and receive a file that passes it on the first attempt. 150 KB is a moderate limit, common for application portals, and this page is preset to exactly that ceiling.
How to compress to 150 KB
- Drop your image into the box above — it stays on your device.
- Confirm the target: under 150 KB as JPEG.
- The MozJPEG encoder searches its quality range so the JPEG output lands just under your limit. Dimensions are left at their original size unless the target demands otherwise.
- Preview the result, compare it with the original if you want, and download — the filename carries its actual size.
Tip: Screenshot-heavy uploads (ID cards, receipts, documents) shrink dramatically; if your portal limit seems impossible for a photo, it is usually trivial for a document scan.
Measured: 150 KB at full frame
The standard 914 KB portrait test file against a bare 150 KB ceiling, dimensions untouched:

6.2× smaller
Quality setting

Quality 24 keeps all 2.7 megapixels — the file reports full size, prints at passport scale, and passes byte checks with margin. The trade stays the same at every budget: a 413×531 passport frame at this ceiling would hold quality in the nineties. Choose based on whether your portal stores the file or shows it.
Frequently asked questions
Is 150 KB enough for a photo meant for printing?
For passport and stamp sizes, comfortably. For a 6×4 print, acceptable. For anything larger, print from the original — compressed uploads are for systems, not for photo labs.
My file came out at 146.7 KB — why not closer to 150?
The encoder climbs the quality ladder and keeps the last step that fits. Between q24 and q25 the file crossed the ceiling, so q24 stands. The output is deterministic: same input, same result, every time.
Can I batch several images at the same 150 KB ceiling?
Yes, and each one lands under the same limit — the target persists across files. Batch processing under a byte ceiling is precisely what quality sliders cannot do.
Can I compress several files for the same portal?
Yes — run each file through the same target page. The settings stay locked, so every file you process here comes out under the same ceiling.
Why JPEG and not another format for my upload?
JPEG is the most universally accepted image format on upload forms and gives the smallest files for photographs. If your destination accepts only "images", JPEG is the safe choice.
What happens to my image when I close the tab?
It is discarded from memory. Nothing was transmitted and nothing was stored, so there is nothing to delete.
