FAQ
How many images can I convert at once?
There is no hard limit — the tool only uses your device's RAM and processing speed. Most modern computers handle 50–100 images comfortably in one batch.
Why convert to WebP?
WebP images are typically 25–35% smaller than JPEG and PNG at the same visual quality, making them ideal for websites and apps.
Does quality setting apply to PNG?
No. PNG is lossless, so the quality slider is hidden when PNG is selected. All other formats (WebP, JPEG, AVIF) use the quality setting.
Are images uploaded to a server?
No. All conversion happens in your browser with the Canvas API. Your images never leave your device.
