Frequently asked questions

Simple answers to your questions

How do I compress a JPG online?
Upload the JPG image through your browser, run the compression process and download the reduced file. Open the result to make sure it has the appearance you need.
Why should I compress a JPG before uploading it?
Large JPGs can slow down uploads, use more storage and exceed image limits on forms or websites. Compression makes the file more manageable for these situations.
Will a compressed JPG have lower quality?
Some quality reduction is possible because JPG compression removes visual data to lower file size. The goal is to balance a smaller file with an image that still looks appropriate for its purpose.
Can I compress JPG photos from a phone?
Yes. You can select a JPG from your phone’s photos or file storage through a mobile browser, then download or share the compressed copy.
