Compress JPG Online

How to use Filesvo

1. Select or drop JPG files, or paste an image from your clipboard.
2. Set the quality — 75% suits most sharing and upload situations.
3. Click Compress Images and download the smaller files.

Choosing a JPG quality level

JPG compression works by discarding image detail the eye is least likely to notice. At 75–85% quality most photos look essentially identical to the original at a fraction of the size. Below about 60%, compression artifacts — blockiness and halos around edges — start to become visible.

Compressing an already-compressed JPG re-encodes it, which always costs a little additional quality even at high settings. For repeated editing, keep a master copy in a lossless format and compress only the final version you share.

Private by design

Your files are processed directly in your browser using the browser's built-in image APIs and are not uploaded to Filesvo. Nothing is stored on our servers, because nothing ever reaches them.

Frequently asked questions

What quality setting should I use?

75% is a solid default for photos being uploaded or emailed. Use 85–95% when quality matters more than size, and 50–70% only when hitting a strict size limit is the priority. The exact size change is shown per file, so you can experiment freely.

Why didn't my JPG get much smaller?

It was probably already compressed to a similar or lower quality level. Re-compressing can't shrink what's already tight — when the result isn't smaller, Filesvo tells you to keep the original rather than pretending there was a saving.

Does compressing a JPG twice ruin it?

Each re-encode loses a little detail, and losses accumulate. One extra compression pass at 75%+ is rarely noticeable; a dozen passes will be. Whenever possible, compress once from the best copy you have.

Is this JPG compressor private?

Yes. Compression runs entirely in your browser — your photos are never uploaded, stored or seen by Filesvo.
