How to use Compress JPG

- Download the compressed images.
Common uses
- Making photos small enough to email.
- Speeding up web pages.
- Saving storage.
About this tool
Re-encode images as JPG at the quality you choose. The result shows the before and after size. Photos usually shrink a lot at quality 60 to 80 with little visible change. For an exact size limit, use the compress to KB tools.
Worked example
Lowering JPG quality from 100 to about 75 often cuts the file to a third or less with little visible difference. Below about 50, blocky artefacts appear around edges.
Common problems and fixes
- Repeated saving loses quality.
- Every re-save of a JPG degrades it a little. Always compress from the original.
- The file did not get smaller.
- Already-compressed images have little left to remove. The tool keeps the original if it cannot improve it.
- Banding in skies.
- Raise the quality a little or choose a larger target size.

Frequently asked questions
What quality should I pick?
70 is a good balance for photos; go lower for thumbnails.
Will it always be smaller?
If compression would make the file bigger, the original is returned.
Are my files uploaded to a server?
No. Everything runs inside your browser on your own device, so your files and text are never sent anywhere.
Is it really free?
Yes. There is no sign-up, no watermark and no limit on how often you use it.
Does it work on my phone?
Yes. It works in any modern browser on phones, tablets and computers. Very large files may be slow on older phones.
Does it work offline?
Once the page has loaded, most tools keep working without a connection, because processing happens on your device.
