Reduce image file size for faster websites, email and sharing. Choose a quality level or a target size in KB. Compare the preview and estimated size before downloading the result. The source file remains unchanged and all processing runs locally in your browser.
Why use this tool
- Choose a quality level or enter an approximate target in KB.
- Reduce transfer and storage size while keeping the original format.
- Preview and process the file locally without sending it to an image server.
How it works
- Choose a JPG, PNG or WebP image and check the preview.
- Choose a quality level or enter an approximate target in KB.
- Apply the operation and download the result in the source format.
How the operation works
The encoder searches for a useful quality near the requested target and can reduce pixel dimensions when quality alone is not enough.
An exact byte size cannot be guaranteed because photographs, graphics and formats compress differently; PNG transparency is retained.
Compress to a specific file size
Use a dedicated preset when you need to aim for a common upload limit.
Private by design
Your files stay on your device. Processing starts only when you choose an image, and nothing is stored on our servers.
Frequently asked questions
Are my images uploaded?
No. Processing happens locally in your browser, so your image files never leave your device.
Can I compress an image to a specific size?
Yes. Enter a target in KB and the compressor will find the closest useful quality automatically.
How does the target size in KB work?
The encoder searches for a useful quality near the requested target and can reduce pixel dimensions when quality alone is not enough.
Will every image reach the exact target size?
An exact byte size cannot be guaranteed because photographs, graphics and formats compress differently; PNG transparency is retained.
Does compressing change my original file?
No. The browser creates a new downloadable result and leaves the selected source file unchanged.
Can I use this tool on a phone?
Yes. Use a current mobile browser that can select a JPG, PNG or WebP file and save downloads.
Which image formats are accepted?
You can use JPG, PNG and WebP. Border and Round export PNG; the other operations keep the input format.
