Compress Image to 150KB
Free tool to compress or reduce any JPG, PNG or WebP image to 150KB online. Runs 100% in your browser – your photos are never uploaded. Perfect for exam & job-application forms.
Need a photo or document under 150KB? Drop your image above and imageto10kb tunes the quality — and the resolution if needed — until the file lands at or under exactly 150KB. Nothing is uploaded; all compression happens on your own device.
A 150 KB allowance is not aimed at passport-sized crops. At 413×531 px a JPEG cannot exceed about 51 KB whatever quality you pick, so it will never fill 150 KB. Targets this size are meant for full-resolution photographs — a postcard photo, or a portrait kept at its original dimensions. Left unresized, a 1240×1593 px portrait lands at about 146 KB against this target, with no loss you could see.
Which forms ask for this size
No portal names 150 KB. It falls inside UPSC photo (20–300 KB), NEET postcard photo (10–200 KB), JEE Main photo (10–200 KB) and NTS photo (50–200 KB).
What to expect at this size
At 150 KB a photograph at ordinary upload dimensions is effectively lossless. A passport crop will land far below it — 413×531 px tops out near 51 KB — so this target is only meaningful for full-resolution images. Reaching 150 KB deliberately takes about 731×939 px at good quality.
How to compress an image to 150KB
- Open imageto10kb. Drag your photo onto the box above, or click to choose a JPG, PNG or WebP file from your device.
- Set the target to 150 KB and leave the resize option switched off. Reducing the dimensions is exactly what prevents a photo from using a 150 KB allowance.
- Click Compress. With the original dimensions intact the result uses close to the full allowance — around 146 KB for a 2 MP portrait — and stays visually identical to the source.
- Download. Check the before/after preview, then download your 150 KB image, ready to upload anywhere.
Frequently asked questions
What kind of photo needs to be 150KB?
A larger one — a postcard photo, or a portrait kept at its camera resolution. Passport-sized crops sit far below this and that is perfectly normal.
Does a larger file mean better quality on my admit card?
Only up to a point. Past roughly 100 KB at these dimensions the extra data is invisible; the printed result looks the same.
How do I compress an image to 150KB?
Upload your image, set the target to 150 KB, and click Compress. imageto10kb searches for the best quality that stays under 150 KB, then lets you download the result.
Will the quality drop?
For small targets like 150KB some quality loss is unavoidable, but the tool keeps the highest quality that still fits, so it looks as good as 150KB allows.
