How many images can I convert at once?

Up to 100 images per batch. All conversion runs locally in your browser — no server, no queue.

Which input formats are supported?

JPEG, PNG, and WebP. For HEIC/HEIF files (iPhone photos), use the dedicated HEIC to JPG converter.

Why should I convert to WebP?

WebP files are typically 25–35% smaller than JPEG at the same visual quality. All modern browsers support WebP, making it the best format for web images in 2026.

Does converting to PNG make the file lossless?

Yes. PNG uses lossless compression — every pixel is preserved exactly. File sizes will be larger than JPEG or WebP for photographic content.

Does the quality slider affect PNG output?

No. PNG is always lossless and ignores the quality setting. The slider only affects JPEG and WebP output.

Are my images uploaded anywhere?

No. All conversion happens using the Canvas API in your browser. Your images never leave your device.
