Is this image compressor free?

Yes. It is free to use with no signup, no watermark and no limits on the number of images.

Are my photos uploaded to compress them?

No. All compression runs locally in your browser using the canvas. Your images never leave your device.

Can I compress to a specific file size?

Yes. Turn on target size, enter a value in KB, and the tool automatically picks the highest quality that fits under that size.

Which formats can I compress to?

You can export as JPG or WebP, both of which use lossy compression. WebP is usually smaller than JPG at the same visual quality.

Will compression reduce image quality?

Lossy compression trades some detail for smaller files. Higher quality settings keep more detail; the live before/after readout helps you find a good balance.

Can I compress multiple images at once?

Yes. Add a batch, apply the same settings, and download every compressed image individually or all together.

How it works

Compressing an image in three steps

Add your images

Drop, browse or paste one or many photos. HEIC files are supported and converted for you.

Choose quality or a target size

Drag the quality slider for a quick balance, or enter a target file size in KB and let the tool find the best quality that fits.

Download smaller files

See the before and after size for every image, then download the compressed JPG or WebP results.

Quality slider or target size

Pick your approach: pull the quality slider from 10% to 100% for a fast size-versus-clarity trade-off, or set a target in kilobytes. Target mode binary-searches the encoder quality to land just under your budget — ideal for upload limits and email attachments.

See the savings instantly

Each result shows the original size, the new size and the percentage saved, plus a total across the whole batch. That makes it easy to hit a page-weight goal or fit inside a form’s file-size cap without guesswork.

On-device and private

Compression runs on the browser canvas — no server round-trip. Your photos never leave your device, so it is fast and private, even for confidential documents and screenshots.
