Compress files online, without the guesswork.
Reduce image sizes with clear quality controls and honest results.
Files are processed on our server in Europe. Download links expire after 60 minutes; files are then deleted automatically.
Why use File Compressor
Private and secure
Your image is sent over an encrypted connection to our server in Europe and stored under a random ID. It is never shared with third parties or used to train AI. Download links expire after 60 minutes; files are then deleted automatically, normally within 75 minutes. Read the privacy policy
Honest results
Choose a quality preset or a target size. The result shows the exact size before and after, and says so if a file can't get any smaller.
Free, no sign-up
File Compressor is free with no account, no watermark and no ads. It works in any modern browser on phone or desktop.
In short
File Compressor makes JPG, PNG and WebP images smaller on our server in Europe. You choose a quality preset or a target size; the result shows the original size, the new size and the exact percentage saved. If a file can't be made smaller, it says so instead of inventing savings. Download links expire after 60 minutes and files are deleted automatically.

How to use it
- Choose or drop an image. The tool detects the type from the file's contents.
- Pick High quality, Balanced or Smaller file, or set a target size.
- Select Compress file. Progress is shown as it happens.
- Compare the sizes and download your file.
What it compresses
JPG, PNG and WebP images, each kept in its own format, with quality presets or a target size for upload limits.
Videos are handled by our sister site, Video Compressor, and PDFs by LoverPDF. If you drop one of those here, we point you to the right place.
Honest results
Every result shows measured byte counts. If a target size can't be reached at an acceptable quality, you get the smallest valid file and a clear "Above target" label. If a file is already well optimized, you can download the original rather than a worse copy.
Questions
Is File Compressor free?
Yes. There's no account, no watermark and no ads.
Do my files leave my device?
Yes. Files are uploaded over an encrypted connection and processed on our server in Europe, then deleted automatically. They aren't shared with third parties or used for AI training.
Why didn't my file get smaller?
Some files are already compressed as far as they can go without visible damage, for example a PNG that was already optimized. We show 0% rather than a misleading number.
What are the size limits?
Images up to 100 MB and 80 megapixels each.
Can I compress PDFs here?
PDF compression is on LoverPDF, our PDF toolkit. Drop a PDF here and we'll link you there.
