How image compression works
Photos hold far more detail than eyes notice. Compression removes the detail you cannot see and stores the rest more efficiently. At the default quality, most photos get 50–80% smaller with no visible change, and you see the before and after size of every file.
When to compress
Use it before uploading to sites with size limits, for email attachments, and for website images where every kilobyte slows the page. To shrink further, also lower the maximum width: a 4000-pixel photo is rarely needed on a screen.

Questions
How much smaller will my images get?
Photos usually shrink by 50–80% at the default quality with no visible difference. You can see the size before and after for every file.
Why is my PNG not getting smaller?
PNG keeps every pixel exactly, so it can only shrink a little. Saving it as WebP or JPG makes it much smaller.
Are my files uploaded anywhere?
No. The conversion runs inside your browser on your own device. Your files are never sent to a server, so they stay private.
Is it really free?
Yes. Every converter on CodeLabX is free, with no sign-up, no watermark and no daily limit.
