Features
Compress & shrink file size
Reduce the file size of JPEG, PNG, WebP and other images while keeping them looking sharp, and see exactly how much each picture saved.
Convert between formats
Export the result as JPG, PNG, WebP or AVIF, so you can slim a file down and switch format in the very same step.
Resize width and height
Optionally fit an image to a target width or height before compressing — handy for uploads that demand smaller dimensions.
Batch compress many images
Drag in or pick several images at once and compress them together, then download each result from the table.
Runs locally in your browser
Compression happens on-device with WebAssembly in a background worker — no upload, no account, no server round trip, and your photos never leave your machine.
Frequently asked questions
Is this image compressor free to use online?
Yes. It is a free online image compressor with no registration, no watermark and no file limits — open the page, drop in your images and start compressing.
Which image formats can I compress?
You can compress common images such as JPEG, PNG, WebP and AVIF, and choose to keep the original format or convert to any of these.
How much can the file size be reduced?
It depends on the image, but photos often shrink by tens of percent. The results table shows each file's original size, new size and the exact percentage saved, so you can judge the trade-off.
Are my images uploaded to a server?
No. Every image is processed locally in your browser using WebAssembly inside a background worker, so files never leave your device and nothing is stored online.
Can I compress several images at once and resize them?
Yes. Add multiple images to compress them in a batch, and optionally fit each one to a target width or height before the compression runs.
