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 PNG to JPEG

PNG is the right choice for graphics that need transparency, but for photos without a transparent background, JPEG is far more efficient — often 5–10× smaller. Converting PNG to JPEG is a quick way to cut file size when transparency is not needed.

This is especially useful for screenshots of photos, images exported from design tools like Figma or Sketch as PNG, or any photo-like image accidentally saved as PNG.

The conversion runs entirely in your browser. A white background is applied to any transparent areas (JPEG does not support transparency). Choose your quality level — 80–85 is the sweet spot for most photos — and download.

Batch conversion is supported: drop multiple PNGs at once and convert them all in seconds.
