Frequently asked questions
How do I reduce an image to a specific size, like 200 KB?
Type 200 in the Max file size box. HD Resizer tries different quality levels and picks the best one that stays under it. If it cannot reach your limit, it tells you, and you can also reduce the width and height.
Why does my PNG not get smaller?
PNG is lossless, so the quality slider does not apply. Switch the format to WebP or JPG for a much smaller file. Use PNG only when you need transparency or perfect pixels.
Which format compresses best?
WebP is usually smallest for the same look, and JPG works everywhere. Photos shrink well in both.
Will compression make my image blurry?
Moderate settings, around 70 to 85 percent, are usually hard to tell apart from the original. Very low settings show blocky areas.
Can I compress many images at once?
Yes. Add several and download a ZIP.
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.
