Frequently Asked Questions

How does this compressor reduce image file size without losing quality?

The tool removes unnecessary EXIF camera metadata, color profile bloat, and optimizes color quantization algorithms, shedding invisible byte overhead while preserving sharp visual clarity for human eyes.

Are my private photographs sent to a remote cloud server?

Never. All compression logic operates 100% inside your web browser sandbox using modern WebAssembly and Canvas APIs. Your photos remain strictly on your local device.

Can I compress multiple image formats at the same time?

Yes. You can upload mixed batches containing JPG, PNG, and WebP formats together. Each image is compressed and reported with its own specific reduction statistics.

What happens if an image cannot be compressed further?

If an image has already been aggressively optimized by other tools, our honest reporter informs you that further compression would degrade visual quality rather than artificially forcing changes.

Is there a limit on how many images I can compress?

There are no usage caps or daily quotas. You can compress as many photos as you need completely free without registering an account or entering credit cards.
