How to compress JPEG files
- Drop your JPG or JPEG photos into the box above.
- Move the quality slider: 70–80% gives the biggest saving with no visible change for most photos.
- Optionally set a maximum width, or a target size in KB.
- Download each photo or all of them at once.
How JPEG compression works
JPEG removes detail that the human eye is not sensitive to, such as tiny colour differences in areas of similar tone. Phones and cameras save photos at very high quality (often 95–100%), which creates large files. Re-saving at around 75% usually cuts the size by 60–80% while the photo looks the same on screen.
Recommended quality settings
- 85–90%: professional photography, product close-ups, images with fine text
- 70–80%: blog and website photos, social media, email
- 50–60%: thumbnails and previews where size matters most

For even smaller files on websites, convert to WebP with JPG to WebP. If a form asks for a specific size, use compress to 100 KB or 50 KB. Your photos are never uploaded: all compression happens on your device.
Frequently asked questions
Is JPEG the same as JPG?
Yes. JPG and JPEG are the same format; the shorter extension comes from old Windows systems that allowed only three letters.
What is the best JPEG quality for the web?
Around 75–80% gives a large size reduction with no visible difference for most photos.
Does compressing remove EXIF data?
Yes. Re-encoding removes EXIF metadata such as camera details and GPS location, which is good for privacy.
