Frequently asked questions
Will compression reduce the quality of my image?+
Slightly — that's how file size is reduced. The quality slider lets you choose the trade-off; most photos look identical at 70–85% quality while being significantly smaller.
Is my image uploaded to a server?+
No. The image is processed entirely in your browser using the Canvas API. Nothing is uploaded, stored, or transmitted.
What output format does the compressor use?+
Images are exported as optimized JPEG, which offers the best size-to-quality ratio for photos and most graphics.
Is there a maximum file size?+
There's no hard limit, but very large images (over ~20 MB) may be slow because your browser has to load them fully into memory.
