Compress JPEG files online
Make your JPEG photos dramatically smaller without an obvious drop in quality. Add one file or dozens — add one or add dozens, with no daily cap and no limit on size.

JPG, PNG and WebP. Set a target in KB and it finds the sharpest result that fits.
Why JPEGs are usually far bigger than they need to be
Phone and camera software saves at a very high quality setting by default, because it has no idea what you will do with the photo. For anything viewed on a screen, that setting is wasteful. Dropping to a well-chosen quality level routinely cuts file size by 60 to 80 percent with no difference visible at normal viewing distance.
Compressing many photos at once
You can select an entire folder of images and compress them in one pass. There is no queue and no daily cap, which is the usual sticking point elsewhere: free tiers that allow two jobs a day are exhausted before a folder of holiday photos is halfway done.
Frequently asked questions
Does compressing a JPEG twice make it worse?
Yes. JPEG compression is lossy, so each save discards a little more detail permanently. Always compress from your original file rather than from a previously compressed copy, and keep the original if you might need it again.
How much smaller will my JPEG get?
Typically 60 to 80 percent smaller at the Balanced setting. Photos with lots of smooth areas such as sky or plain walls shrink the most; images dense with fine texture shrink least.
Is there a limit on how many files I can compress?
No. There is no cap, no account and no watermark, whether you are compressing one photo or a folder of them.
