Frequently Asked Questions
Which format gives the smallest file size?
WebP typically gives the smallest files at the same quality. JPEG is a close second. PNG is best for images with transparency or sharp edges but produces larger files.
Does this reduce image dimensions?
No, only file size is reduced by adjusting compression quality. Use the Image Resizer tool to change dimensions.
Is my image uploaded to a server?
No. All compression happens in your browser using the Canvas API. Your images never leave your device.
Why does PNG ignore the quality slider?
PNG is a lossless format — it always preserves full quality. Choosing PNG is useful for format conversion but won't reduce file size as much as JPEG or WebP.
