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 HEIC to JPEG

iPhones capture photos in HEIC (High Efficiency Image Container) format by default. While HEIC produces excellent quality at small file sizes, many Windows apps, websites, and services do not support it — JPEG remains the universal standard.

Safari on macOS and iOS can decode HEIC natively, so this tool can convert HEIC to JPEG directly in your browser on those platforms. On other browsers you may need to enable HEIC support first.

Drop your HEIC files, select JPEG as the output format, and choose a quality setting (85 is recommended for photos). The converted JPEGs will be ready to share anywhere: email, social media, Windows PCs, or any photo service.

For the best compatibility and file size balance, JPEG at quality 85 is the standard choice for sharing iPhone photos online.
