Quick answer

Open the photo resizer, load your image, enter a maximum size in KB, and pick JPEG or WebP. The tool lowers quality step by step and tells you the real size it reached. If it cannot reach the target it says so.

Steps

Choose the image. Leave the aspect-ratio lock on unless the form needs exact pixel dimensions. Enter the target in KB. Check the result size shown under the preview, then download.

Why a target can fail

File size depends on pixels, detail and quality. A large, detailed photo may stay above a small target even at very low quality. Reduce the width and height first, then try again. PNG files do not shrink with quality, so switch to JPEG if the form allows it.

Check the rules

Forms differ. Read the size, format and dimension rules in the official notice for your application; this guide does not quote any.

Frequently asked questions

Can the tool guarantee an exact file size?

No. The target is best effort: the tool lowers quality step by step and tells you the size it reached or that it could not get there.

Which format gives the smallest file?

For photos, JPEG and WebP are usually smaller than PNG. PNG ignores the quality setting.
