Compress Image to 450KB

Upload your photo, check that the target says 450 KB and click the compress button. Your smaller image is ready to download in a few seconds.

Yes, whenever possible. The tool never goes over 450 KB — it finds the best look that fits. If a picture can't get that small, you'll see a clear message and get the smallest version we could make.

Some websites count file size slightly differently, so a file right at the limit can still be rejected. 450 KB keeps a safe margin while staying sharp.

At 450 KB images look sharp and detailed on phones and computers, with no visible loss for most photos.

Not quite. Compressing makes the file smaller (KB/MB). Resizing changes the width and height in pixels. This tool does both when needed to reach your target.

It depends on the photo, but as a guide a typical phone photo comes out about 2,600–3,400 px wide at 450 KB, with good quality. Simple pictures like signatures can stay wider; busy, detailed photos come out a little smaller.

450 KB gives about 12% more room than 400 KB, so photos come out a little wider (about 2,600–3,400 px instead of 2,450–3,200 px) and sharper. Always pick the biggest size your form or website allows — it gives the best quality.

First set the exact pixels with Image Resizer, then compress the result here. Leave Max Width empty so the size stays the same.

Yes. PNG stays PNG and keeps its sharp edges. For photos saved as PNG, converting to JPG first gives a much smaller file.

Yes. JPG stays JPG, PNG stays PNG and WEBP stays WEBP, so the website you upload to accepts the same format you started with.

Yes. Select several images together. Each one is compressed to your target size, and you can download them all in one ZIP file.
