Frequently Asked Questions
Which image formats does the compressor support?
It supports JPEG, PNG, and WebP — the three most common formats. You can keep the original format or choose an output format, and batch processing is supported.
Will compression reduce image quality?
You can freely adjust the compression quality (10%–100%) and maximum width/height. We recommend WebP at 60%–80% quality for web images to balance file size and visual fidelity.
Are images uploaded to a server?
No. All processing happens locally in your browser via the Canvas API — nothing is uploaded, so your privacy is protected.
Is there a file size limit?
There is no hard limit. You can drag in multiple images at once for batch compression; very large images are automatically downsampled to keep the browser responsive.
