Image Compressor & Converter
Shrink photo file sizes and convert to WebP, JPG, or PNG. Everything happens inside your browser — your images are never uploaded to a server.
How to use
- 1
Drag and drop images, or click to pick them. You can add multiple files at once.
- 2
Choose the output format (WebP recommended), quality, and max size. Quality 0.7–0.85 gives the best size-to-quality ratio.
- 3
Check the savings, then download files individually or grab everything as a ZIP.
Frequently asked questions
Are my images uploaded to a server?
No. All compression and conversion happens inside your browser. Your images never travel over the network, so private or sensitive photos stay on your device.
Which formats are supported?
Input: any image your browser can read — JPG, PNG, WebP, and more. Output: WebP, JPG, or PNG. Some older browsers cannot encode WebP; in that case the option is hidden automatically.
What quality setting should I use?
For regular photos, 0.7–0.85 is recommended. In that range the visual difference is hard to notice while the file size drops significantly. For document scans or text-heavy images, use 0.85 or higher.
Why convert to WebP?
WebP is a modern format that is typically 25–35% smaller than JPG at the same visual quality. It is ideal for websites and blogs, and opens in virtually every modern browser.
My PNG did not get smaller. Why?
PNG is lossless, so simply re-saving it often cannot reduce the size — it may even grow. When that happens the tool keeps your original and marks it "already optimized". For photos, converting to WebP or JPG is far more effective.
How many images can I compress at once?
There is no hard limit. Speed and memory depend on your device, so for hundreds of images we recommend processing them in batches.
Is it really free?
Yes — free, unlimited, and watermark-free. Because processing happens on your device, there are no server costs to pass on.
