Why this size

When a 150 KB limit makes sense

Many online forms and website builders stop at 150 KB. At this size a photo still looks sharp on screen, and pages and uploads stay quick.

Most photos reach 150 KB with quality changes alone, so the dimensions usually stay exactly as they were.

Upload	Typical limit
Online form	100-200 KB
Profile photo	50-100 KB
Document scan	100-300 KB
Website image	100-200 KB

Tips

Tips that make a difference

Crop first

Cropping to just the face or document removes pixels you do not need, so the quality can stay higher.

Use JPG

JPG gets much smaller than PNG for photos. Use PNG only if the form asks for it.

Check the dimensions too

Some portals also require a size such as 3.5 x 4.5 cm or 200 x 230 px. Set both to avoid a second rejection: resize in cm or in pixels first, then compress.

Plain backgrounds compress better

A plain wall behind you leaves more of the 150 KB for your face.

FAQ

Compress to 150KB: questions

Add your photo above and download the result. The 150 KB target is already set: the tool lowers the JPG quality step by step, and the pixel size only if it must, until the file is just under 150 KB.

Open this page in Chrome or Safari, tap to pick a photo or take a new one, then download. It works on Android and iPhone with nothing to install.

Only if it has to. The tool first lowers the quality at full size, and shrinks the image only when 150 KB is still out of reach.

No. At 150 KB most photos look the same as the original on screen.

The result lands just under the limit, usually within a few percent of 150 KB, so the form never rejects it for being too big.

Add a PNG, HEIC, WebP or JPG photo. The result is always a JPG just under 150 KB, so converting and compressing happen in one step.

Use JPG to PDF under 150 KB: it turns one photo or several pages into one PDF under 150 KB. A PDF upload field rejects a JPG even when the size is right.

No. Compression runs in your browser on your own device. The photo never reaches our servers.

Yes. Drop several photos and each one is compressed to the same target. Download them one by one or together as a ZIP. For a large batch, the bulk image compressor is made for it.

Checked

How we checked this page

Checked by the SizePort team on 3 October 2026.

We test the tool with sample photos before it goes live and check that the sizes on this page match what it produces. Rules and platforms change, so if something here is out of date, tell us and we will correct it.

How the tool works

The compressor first lowers the JPG quality at full resolution, testing several settings until the file is just under the target. Only if quality alone cannot get there does it reduce the width and height, a little at a time. The result is a JPG. Everything happens in your browser; your images are never uploaded.
