Compress images online

How this compression flow works

Our resizer lets you scale down oversized pixels (often the biggest win from phone cameras) and reduce encoder quality for lossy formats. Start with the longest edge — for example 1600px or 1920px — before you chase extreme quality numbers.

For PNG screenshots, compression helps less than for photos; sometimes converting to JPEG or WebP is the right next step using our converters after you have a master PNG.

When to compress vs convert format

If the file is already JPEG, lowering quality and moderate resizing usually hits form upload limits fastest. If you serve a modern site, JPEG to WebP or PNG to WebP often beats raw JPEG compression for the same visual weight.

HEIC images from iPhones should be converted first — use our HEIC tools — then you can compress the JPEG or WebP output.

After compressing: host or share

Need a link for Discord, GitHub, or a forum? Upload the compressed file to our image host and copy the direct URL from the image page.

Developers can automate uploads with the documented REST API when batch workflows outgrow the browser UI.
