How to compress an image to 150 KB
- Drag your JPG, PNG or WebP into the box above — it's read straight into your browser, never uploaded.
- The target is already set to 150 KB; FileTinker re-encodes the image until it fits at or under that size.
- Preview the result and download. If 150 KB is too small for this image, you're told clearly instead of handed a broken file.
About compressing to 150 KB
Compressing to 150 KB reduces a photo's file size by re-encoding it more efficiently and, when needed, lowering quality slightly — handy for upload limits, email attachments and forms that cap files at 150 KB.
Everything runs in your browser, so your image never leaves your device. JPG and WebP reach small targets like this most easily; very small targets may trade away some visible quality.
150 KB is a common ceiling for CMS uploads, marketplace listings and web forms that are generous enough for a real photo. An image around 1200 to 1500 pixels wide typically lands here with quality loss you have to squint to notice, which makes 150 KB a comfortable target for product shots and article images.
Frequently asked questions
How do I compress an image to 150 KB?
Drag your JPG, PNG or WebP into the tool above, leave the target at 150 KB, and press Compress. FileTinker shrinks it to 150 KB or under in your browser, then you download the result.
Will compressing to 150 KB reduce the quality?
Smaller targets mean more compression, so some quality is traded for size. FileTinker keeps the highest quality that still fits under 150 KB; if 150 KB is very small for a detailed photo, the tool tells you the closest size it could reach.
Are my images uploaded anywhere?
No. Compression happens entirely in your browser — your image never leaves your device and nothing is stored on a server.
Which formats can I compress to 150 KB?
JPG, PNG and WebP. The compressed file keeps its original format.
Why did my image come back unchanged?
If your file is already at or under 150 KB, the tool returns the original untouched rather than re-encoding it — re-compressing an already-small file would only lose quality without making it meaningfully smaller. You'll see it reported as already optimal.
