Compress JPG
Shrink JPEG file size while keeping photos sharp, in your browser
Make your JPEGs smaller without the fuss
A JPG straight from a phone or camera can be several megabytes, more than most inboxes, forums and web forms want to handle. Compressing re-encodes the photo at a lower quality setting, squeezing out file size while keeping the picture looking right. The result uploads faster, attaches cleanly to email and takes up far less storage.
This compressor lets you decide the balance. Slide toward smaller for the lightest file, or toward higher quality when detail matters. Every step runs in your browser, and you can compress a whole folder of images at once and download them as a ZIP.
How to compress a JPG
- Drop your JPG or JPEG files into the box above, or click to select them.
- Drag the quality slider; lower means a smaller file, higher keeps more detail. Around 75 to 80 is a great everyday balance.
- Watch the before and after file sizes update as you adjust.
- Click Download compressed JPG, or download the whole batch as a ZIP.
Why compress JPG images?
Faster uploads and emails
Smaller files send and upload in a fraction of the time and sail past attachment size limits that block big originals.
You control the tradeoff
The live size readout lets you find the sweet spot where the photo still looks great but the file is a fraction of its original weight.
Bulk compression, kept private
Compress dozens of photos in one pass. It all happens on your device, so nothing is uploaded to a server.
Frequently Asked Questions
How does JPG compression work here?
The tool re-encodes your image at the quality level you choose. JPEG discards fine detail the eye barely notices, so the file gets much smaller while the photo still looks sharp.
How small can the file get?
It depends on the photo and the quality you pick. Reductions of 50 to 80% are common at moderate quality; push the slider lower for even smaller files.
Will compressing blur my photo?
At high and medium settings the change is hard to see. Very low quality can introduce soft blocks, so use the preview to stop before that point.
Can I compress many JPGs at once?
Yes. Add a batch, set one quality level and download every compressed image in a single ZIP.
Are my images uploaded?
No. Compression happens entirely in your browser, so your photos never leave your computer.
