About Image Compressor
Compress your images without losing quality. Adjust quality and maximum width settings to get the perfect balance between file size and image quality. All processing is done locally in your browser.
What Is This Tool?
Our image compressor reduces image file size directly in your browser — files are never uploaded to any server. Drop in one or more images, adjust the quality and maximum width, and the tool re-encodes each one as a compressed JPEG. See the size savings for every image and download them individually or all at once.
How to Use
- Drag and drop one or more images onto the upload area, or click to browse your files.
- Adjust the quality slider (10-100%) to balance file size vs. image quality.
- Adjust the max width slider to shrink oversized images — anything wider is scaled down proportionally.
- Each image's compressed preview and new size appear automatically.
- Click Download on an image, or Download All to save every compressed image at once.
Common Use Cases
- Optimizing website images to improve page load speed
- Reducing photo file size before emailing or uploading to a web form
- Preparing photos for social media where file size limits apply
- Batch-compressing a folder of photos at once without installing software
Tips & Tricks
- A quality setting of 75-85% usually gives an excellent balance of size and visual quality.
- Lowering the max width alongside quality gives the biggest size reduction for images that don't need to stay full resolution.
- Compare the original and compressed size shown under each image before downloading.
Frequently Asked Questions
What image format does the compressed file use?
Every image is re-encoded as JPEG, regardless of the original format. This gives the best compression for photos but isn't ideal for images that need transparency.
Are my images uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API. Your files never leave your device.
Can I compress multiple images at once?
Yes. Drop in or select several files at once, and use Download All to save every compressed image in one go.
How much can the max width slider reduce file size?
Significantly, if your original image is much larger than needed. Shrinking a 4000px-wide photo down to 1920px, for example, can cut file size well beyond what quality adjustment alone achieves.
