Free Online Image Compressor
This tool reduces the file size of your images while keeping them looking sharp. Whether you need to shrink a large photo for email, meet an upload limit, or compress an image to an exact size such as 20KB, 50KB, or 100KB, you can do it here in seconds — no software to install and no account required.
Two ways to compress
Use the Slider tab to choose a compression level from 1–100% and see exactly how much smaller each image becomes. Or switch to the Size tab, type a target like 20KB, and the tool automatically finds the right quality — and downscales the image if needed — to hit that size.
Supported formats
Compress JPG, PNG, WEBP, GIF, AVIF, BMP, and TIFF images. Each format also has its own dedicated page with format-specific tips. Your files are automatically deleted from our server 10 minutes after upload, so your images stay private.
Fast & Private
Images are compressed directly on our server — no external APIs, nothing shared with third parties.
Compress to Exact Size
Need a file under 20KB, 50KB, or 100KB? The Size tab hits your target automatically.
Auto-Delete in 10 Min
Uploaded and compressed files are wiped 10 minutes after creation. Nothing is kept permanently.
Batch & ZIP
Compress many images at once and download them together in a single ZIP archive.
Frequently Asked Questions
Is this image compressor free?
Yes. Every feature is free with no sign-up. Images are processed on our server using PHP GD and ImageMagick — no third-party API is involved.
How long are my files kept?
Every uploaded and compressed file is automatically deleted 10 minutes after it is created. A cleanup task also runs regularly as a safety net.
Can I compress an image to an exact size like 20KB?
Yes — use the "Size" tab, type your target (for example 20 KB), and the tool compresses and, if necessary, downscales the image to reach it.
Will compression reduce image quality?
Some quality is traded for smaller size, but at the default levels the difference is usually hard to notice. Use the slider to find the balance you like.
