Compress JPG Online Without Uploading
JPG photos from cameras and phones are often several megabytes. When you need to send them by email, upload them to a form, or place them on a website, that size can become a problem. This page helps you shrink JPG files by adjusting quality and output format, without uploading your photos to a server. You can preview the result before saving, so it still looks good.

Quick guide
How it works Compress JPG Online Without Uploading
-
Choose a JPG photo
Open a .jpg or .jpeg file from your device. The photo stays in your browser, so no data is sent over the internet. If the photo is larger than 10 MB, reduce its dimensions first in the Resize Photo tool.
-
Set the output quality
Move the quality slider and choose JPG as the download format. Start at 80 percent, then lower it gradually if the file is still too large. Watch small text, faces, and sky gradients so they do not break up.
-
Check the size and download
Use the size calculation button to see the final result before saving. Compare it with the original file, then download it if the detail is still sufficient. Repeat with another quality setting if needed.
FAQ
Frequently asked questions
What is an ideal JPG size for email?
Some email services limit attachments to about 20–25 MB, but 1–2 MB per photo is enough for on-screen viewing. For several photos at once, compress each one and consider sharing a cloud link.
Can JPG quality be restored to the original?
No. JPG compression is lossy, so discarded detail cannot be recovered. Always keep the original file and create a new copy each time you compress.
Why is my compressed JPG larger instead?
That can happen if quality is near 100 percent or the original photo is already heavily compressed. Lower quality to 75–85 percent and avoid saving the same file repeatedly.
Is location metadata removed as well?
When a photo is rewritten, EXIF metadata is generally not preserved. This is good for privacy, but keep the original file if you still need the camera data.
