Resize Image to 150KB
150 KB is enough for a sharp photo or a readable full-page scan, and it is a common per-file cap on job, school and document uploads. This preset keeps as many pixels as it can and writes a JPG.

Target size picks the quality for you and never goes over the limit you set.
The result is never larger than this. If a size cannot be reached by quality alone, the image is scaled down to fit.
Free compresses one image at a time.
Free exports up to 4096px on the longest side
What 150 KB buys you
At 150 KB a JPG can hold a photo of around a megapixel at good quality — roughly 1200 × 900 pixels — or a full page scanned at a resolution where body text is still crisp. That is where uploads stop looking compressed. A modern phone photo is still 15–30 times larger, so most will be scaled down a little, but far less than on the 10–50 KB pages.
Getting under 150 KB
- For a document, crop off the desk or background around the page first — every byte spent there is resolution the text loses.
- Drop the image here. The target is already 150 KB and the output is JPG.
- Download and check the size before you upload.
What 150 KB keeps
- Photos keep skin, hair and fabric detail; artefacts only show if you zoom right in.
- Text in a one-page scan stays readable at 100% zoom, which is how reviewers look at it.
- A scan that comes back soft usually had lots of background around the page; cropping to the page restores the resolution.
Where a 150 KB limit usually appears
- Certificates, mark sheets and ID scans on portals that cap each file at 100–200 KB.
- Photos for job applications, school admissions and membership forms.
- Listing and email images where you want fast loading without visible loss.
Why this page writes JPG
Above 100 KB this template writes JPG: it is accepted everywhere a photo or scan is, and at 150 KB it already looks clean, so WebP's extra saving buys nothing a reviewer would notice.
How the 150 KB preset works
- Target: 150 KB, counted as 153,600 bytes; the output is never above it.
- Most photos are compressed with little or no resizing, and a small source can come back at full size.
- Several pages in one file? Combine them into a PDF and use the PDF compressor instead — it keeps text selectable.

FAQ
Will a 150 KB photo look good?
On screen, yes. 150 KB holds a photo of around a megapixel at a high quality setting, which is sharper than most upload forms display. Zoomed right in you may see slightly softer fine texture than the original.
Is 150 KB enough for a scanned document?
For one page, usually. Crop to the page edges so no bytes go to the desk around it, and body text stays readable. For several pages, put them in one PDF and use the compress PDF to 200 KB page.
Why did the tool leave my image at full size?
Because it already fitted. If a high-quality JPG of your image is under 150 KB, there is nothing to gain by shrinking it, so the dimensions are left alone.
Can I keep PNG?
Not on this page — it writes JPG, because a photographic PNG rarely fits in 150 KB without becoming very small. The main image compressor lets you choose PNG, WebP or AVIF instead.
