How to use Compress JPG

  1. Add JPG files straight from your camera, phone export or downloads.

  2. Set the quality slider — start at 80%.

  3. Click Compress JPG and check the reduction for each file.

  4. Download the smaller files.

About this tool

Cameras and phones save JPGs at very high quality settings that most uses don't need. Re-encoding at 75–85% quality routinely halves the file size with no visible difference at normal viewing sizes — useful for email limits, form uploads and faster web pages. Because each JPG re-encode is lossy, compress from your original file rather than compressing the same file repeatedly.

This tool is specifically tuned for JPG-to-JPG compression, so if most of your files are already JPGs straight from a phone or camera, it's a more direct route than the general Image Compressor.

Common ways people use this

  • Shrinking phone photos before sending them by email or messaging apps with attachment limits
  • Getting a batch of camera JPGs small enough to fit an upload form's size cap
  • Speeding up a website by reducing the size of existing JPG images without changing format

Tips for better results

  • Compress from the original camera or phone file rather than a copy that's already been compressed once, to avoid stacking quality loss.
  • If a photo will only ever be viewed on a phone screen, you can usually go a bit lower on quality than for one that might be printed or zoomed into.

Frequently asked questions

How small can I make a JPG before it looks bad?
For photos viewed at normal size, 70–85% quality is usually indistinguishable from the original. Below about 60% you may notice blockiness around edges. The size readout helps you stop at the right point.
Does compressing change the image dimensions?
No — width and height stay the same. If you also want smaller dimensions, run the file through the Image Resizer, which reduces size even further.
Are photos uploaded to your server?
No. Compression runs in your browser; the file never leaves your device.
Is there a difference between this and the general Image Compressor?
This tool is focused specifically on JPG in, JPG out. The Image Compressor also accepts PNG and WebP input and lets you choose a different output format.
Can I compress a whole folder of vacation photos at once?
Yes, add them all in one batch — each is compressed with the same quality setting and can be downloaded individually.
