Compress images online in your browser. Reduce file size for websites, email, and storage while keeping visual quality under your control—no account and no server upload.
An image compressor reduces file size so pages load faster and attachments stay within limits. IMG Free Toolkit runs compression in your browser for JPG, PNG, and WebP files.
You stay in control of quality presets and the quality slider. Preview results before you download, and process multiple images in one session.
1. Open the free image compressor on this page.
2. Select one or more JPG, PNG, or WebP images from your device.
3. Choose a quality preset (High Quality, Balanced, or Small Size) or adjust the slider.
4. Review the estimated size savings, then download each file or download all at once.
JPG (JPEG) is already a lossy format, so further compression usually means lowering quality. Start with a balanced setting for photos, then reduce only as much as you need for the web or sharing.
If a photo still feels large after compression, consider resizing dimensions first, then compressing again.
PNG is often used for graphics with sharp edges or transparency. Compression still helps, but PNGs with lots of detail may stay relatively large compared with JPG or WebP.
When transparency is not required, converting PNG to JPG or WebP can shrink files more aggressively than PNG-only compression.
WebP often delivers smaller files than JPG at similar visual quality, which is why many websites prefer it. You can compress existing WebP images here or convert JPG files to WebP with our converter.
Use WebP when your audience and CMS support it; keep JPG when you need maximum compatibility.
Savings depend on the original format, resolution, and quality setting. High-resolution camera photos often shrink substantially. Already-optimized web assets may shrink less.
Aim for the smallest file that still looks good for your use case—hero images and product photos usually need higher quality than thumbnails.
Compression reduces file size by changing how image data is encoded. Resizing changes width and height. Oversized images waste bytes even at high compression quality.
For websites, resize to the display size you need, then compress. Use the Image Resizer when dimensions are the main problem, and this compressor when quality/size trade-offs matter most.
You can compress JPG, JPEG, PNG, and WebP images. Each file can be up to 25 MB, and you can process up to 10 images at a time.
No. Compression runs entirely in your browser. Your images are not uploaded to our servers.
Compression involves a quality trade-off. Use High Quality, Balanced, or Small Size presets—or the slider—to balance file size and visual quality.
If the image is much larger than you need to display, resize it first. Smaller dimensions usually reduce file size more effectively than compression alone.
