Is my photo uploaded anywhere?

No. Compression happens 100% inside your browser using the Canvas API. Your files never leave your device — no server, no cloud, no upload.

What image formats are supported?

You can compress and convert JPEG, PNG, WebP, and AVIF images. HEIC/HEIF from iPhones is supported in Safari on macOS and iOS.

How much can I reduce file size?

Typically 60–80% at quality 80. A 3 MB JPEG often compresses to 400–700 KB with no visible quality difference on screen.

Yes, completely free. No account, no watermarks, no limits on the number of images.

Does it work on iPhone and Android?

Yes. The tool is mobile-first and works in Safari, Chrome, and Firefox on both iOS and Android.

Can I compress multiple images at once?

Yes. Drop as many images as you like, click "Compress all", then download them individually or as a ZIP file.

Which format should I choose — JPEG, WebP, or AVIF?

WebP is the best choice for most use cases: widely supported and 25–35% smaller than JPEG. Choose AVIF for maximum compression (Chrome/Firefox/Safari 16+). Use JPEG for maximum compatibility with older software.

What quality setting should I use?

Quality 80 is the default and works well for most photos. Go down to 70 for smaller files, or up to 90 for near-lossless quality. Below 60 is rarely useful.

Convert JPG to AVIF

AVIF is the newest image format based on the AV1 video codec. It delivers 40–50% smaller files than JPEG at equivalent visual quality — even better than WebP. Chrome, Firefox, and Safari 16+ all support AVIF natively.

Converting JPG to AVIF is ideal when you need the smallest possible file size: mobile web pages, progressive web apps, or e-commerce product images where every byte counts.

This tool converts your JPEG photos to AVIF directly in the browser. If your browser does not support AVIF encoding, it automatically falls back to WebP so you always get the best available format.

AVIF encoding is slightly slower than JPEG or WebP due to its advanced compression algorithm, but the file size savings are significant — especially for photo-heavy pages.
