About this tool
Make your image smaller than 20KB. HD Resizer tries different quality levels and keeps the best one that fits. If the picture is still too big, it also reduces the width and height a little at a time until it fits, and the estimate shows the final size. Typical reasons are form uploads, email limits and job or visa portals.
How to use it
- Add your image. The 20KB limit is already set.
- Check the estimate. Choose WebP or JPG for the smallest files, and PNG only if you need it.
- Press Compress & Download.
Frequently asked questions
How do I reduce an image to under 20KB?
Add the image and press Compress & Download. The 20KB limit is already filled in. You can change it in the Max file size box.
Will my image get blurry at 20KB?
Small limits mean lower quality. The tool lowers quality first and only reduces the dimensions if it has to. Photos shrink well, but screenshots with fine text can look soft at very small sizes.
Why does my PNG not get smaller?
PNG is lossless and ignores the quality setting. Choose JPG or WebP for the target size.
What if the portal needs JPG?
Choose JPG as the format. Most portals accept JPG, and the tool also opens PNG, WebP and iPhone HEIC photos.
Can I compress several images?
Yes. Add them all and download a ZIP. Each one is brought under the limit.
Is it free?
Yes. It is free to use, with no sign-up and no watermark.
Are my photos uploaded anywhere?
No. HD Resizer runs entirely in your browser, so your images stay on your device. Nothing is sent to a server, and there is no account or watermark.
